+# LLGo Project AI Assistant Guide
+
+This document provides essential information for AI assistants to help fix bugs and implement features in the LLGo project.
+
+## About LLGo
+
+LLGo is a Go compiler based on LLVM designed to better integrate Go with the C ecosystem, including Python and JavaScript. It's a subproject of the XGo project that aims to expand the boundaries of Go/XGo for game development, AI and data science, WebAssembly, and embedded development.
+
+## Project Structure
+
+- `cmd/llgo` - Main llgo compiler command (usage similar to `go` command)
+- `cl/` - Core compiler logic that converts Go packages to LLVM IR
+- `ssa/` - LLVM IR file generation using Go SSA semantics
+- `internal/build/` - Build process orchestration
+- `runtime/` - LLGo runtime library
+- `chore/` - Development tools (llgen, llpyg, ssadump, etc.)
+- `_demo/` - Example programs demonstrating C/C++ interop (`c/hello`, `c/qsort`) and Python integration (`py/callpy`, `py/numpy`)
+- `_cmptest/` - Comparison tests to verify the same program gets the same output with Go and LLGo
+
+## Development Environment
+
+For detailed dependency requirements and installation instructions, see the [Dependencies](README.md#dependencies) and [How to install](README.md#how-to-install) sections in the README.
+
+## Testing & Validation
+
+The following commands and workflows are essential when fixing bugs or implementing features in the LLGo project:
+
+### Run all tests
+```bash
+go test ./...
+```
+
+**Note:** Some tests may fail if optional dependencies (like Python) are not properly configured. The test suite includes comprehensive tests for:
+- Compiler functionality
+- SSA generation
+- C interop
+- Python integration (requires Python development headers)
+
+### Write and run tests for your changes
+
+When adding new functionality or fixing bugs, create appropriate test cases:
+
+```bash
+# Add your test to the relevant package's *_test.go file
+# Then run tests for that package
+go test ./path/to/package
+
+# Or run all tests
+go test ./...
+```
+
+**Important:** The `LLGO_ROOT` environment variable must be set to the repository root when running llgo commands during development.
+
+### Maintain LLVM IR checks by test intent
+
+Do not refresh every FileCheck assertion after an IR change. First identify the
+single compiler property a test is intended to protect, then keep the smallest
+handwritten assertions that prove that property. Runtime output and focused IR
+checks protect different contracts; avoid only the redundant full IR snapshot.
+
+Treat 100 FileCheck directive lines as a review threshold, not a hard limit.
+Above that threshold, verify that each handwritten group protects a distinct,
+named semantic contract. If the test instead needs a long contiguous IR shape,
+make that region reproducible with `litgen`.
+
+The repository keeps a curated set of source-embedded autogenerated checks for
+cases where a broad function or module shape is itself the contract. They
+remain in the Go source and carry a reproducible `UTC_ARGS` note:
+
+```go
+// LITTEST
+// NOTE: Assertions have been autogenerated by chore/litgen UTC_ARGS: --function=run --check-globals=smart
+```
+
+Declare known platform differences with a target matrix and exact FileCheck
+prefixes instead of regular-expression alternatives. The ordinary marker uses
+the historical pre-ABI stage; only checks after target ABI lowering need an
+explicit stage:
+
+```go
+// LITTEST darwin/arm64 linux/amd64
+// LITTEST: POST-ABI linux/amd64 linux/arm64
+```
+
+The harness cross-compiles IR for every listed target, independent of the host.
+It also always checks the fixture's current effective target; listed targets are
+additional coverage and are deduplicated against the current target.
+FileCheck enables `CHECK`, the GOARCH prefix, and the exact target prefix (for
+example `CHECK,ARM64,DARWIN-ARM64`). Put assertions shared by targets with the
+same architecture under `ARM64`, `AMD64`, and similar architecture prefixes.
+Fixtures that depend on cgo still require the corresponding target C toolchain
+and sysroot, so keep them on plain `// LITTEST` unless CI provides those inputs.
+
+Refresh and verify all opted-in snapshots with:
+
+```bash
+go run ./chore/litgen -u cl
+go run ./chore/litgen -u --check cl
+```
+
+`litgen` will not replace a handwritten test during update-only operation. When
+creating an autogenerated test, pass one or more `--function` expressions; use
+`--all-functions` only for a deliberate whole-module contract. See
+`dev/README.md` for the complete options and marker conventions.
+
+## Code Quality
+
+Before submitting any code updates, you must run the following formatting and validation commands:
+
+### Format code
+```bash
+go fmt ./...
+```
+
+**Important:** Always run `go fmt ./...` before committing code changes. This ensures consistent code formatting across the project.
+
+### Run static analysis
+```bash
+go vet ./...
+```
+
+**Note:** Currently reports some issues related to lock passing by value in `ssa/type_cvt.go` and a possible unsafe.Pointer misuse in `cl/builtin_test.go`. These are known issues.
+
+
+## Common Development Tasks
+
+### Build the entire project
+```bash
+go build -v ./...
+```
+
+### Build llgo command specifically
+```bash
+go build -o llgo ./cmd/llgo
+```
+
+### Check llgo version
+```bash
+llgo version
+```
+
+### Install llgo for system-wide use
+```bash
+./install.sh
+```
+
+### Build development tools
+```bash
+go install -v ./cmd/...
+go install -v ./chore/...
+```
+
+## Key Modules for Understanding
+
+- `ssa` - Generates LLVM IR using Go SSA semantics
+- `cl` - Core compiler converting Go to LLVM IR
+- `internal/build` - Orchestrates the compilation process
+
+## Debugging
+
+### Disable Garbage Collection
+For testing purposes, you can disable GC:
+```bash
+LLGO_ROOT=/path/to/llgo llgo run -tags nogc .
+```
+
+## LLGO_ROOT Environment Variable
+
+**CRITICAL:** Always set `LLGO_ROOT` to the repository root when running llgo during development:
+
+```bash
+export LLGO_ROOT=/path/to/llgo
+# or
+LLGO_ROOT=/path/to/llgo llgo run .
+```
+
+## Important Notes
+
+1. **Testing Requirement:** All bug fixes and features MUST include tests
+2. **Demo Directory:** Examples in `_demo` are prefixed with `_` to prevent standard `go` command from trying to compile them
+3. **Defer in Loops:** LLGo now supports `defer` within loops, matching Go's semantics of executing defers in LIFO order for every iteration. Be mindful of loop-heavy defer usage as it allocates per iteration.
+4. **C Ecosystem Integration:** LLGo uses `go:linkname` directive to link external symbols through ABI
+5. **Python Integration:** Third-party Python libraries require separate installation of library files

+                        http://www.apache.org/licenses/
+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+          that such additional attribution notices cannot be construed

+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+    5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+    6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+    7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+    8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+    9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Compatibility is checked against applicable upstream [`GOROOT/test`](test/goroot/README.md) cases using pinned Go 1.25 and Go 1.26 toolchains. Remaining applicable differences are recorded in [`xfail.yaml`](test/goroot/xfail.yaml); gc-specific mechanisms outside LLGo's compatibility goals are documented in [`notapplicable.yaml`](test/goroot/notapplicable.yaml).
 
-Here is a simple example:
+### Runtime
 
-<!-- embedme doc/_readme/llgo_simple/simple.go -->
+LLGo uses a different runtime from the standard Go toolchain. Native goroutines map 1:1 to OS threads with fixed native stacks, so direct C calls require no Go-to-C stack or scheduler transition, avoiding the cgo overhead that makes frequent C calls costly in standard Go.
 
-```go
-package main
+The default garbage collector is conservative [BDWGC](https://www.hboehm.info/gc/) (also known as libgc). Bare-metal embedded targets instead use a TinyGo-derived conservative mark-and-sweep collector.
 
-import "github.com/goplus/lib/c"
+Garbage collection can be disabled with the `nogc` build tag. For example:
 
-func main() {
-	c.Printf(c.Str("Hello world\n"))
-}
+```sh
+llgo run -tags nogc .
 ```
 
-This is a simple example of calling the C `printf` function to print `Hello world`. Here, `c.Str` is not a function for converting a Go string to a C string, but a built-in instruction supported by `llgo` for generating a C string constant.
+### Standard libraries
 
-The `_demo` directory contains some C standard libary related demos (it start with `_` to prevent the `go` command from compiling it):
+LLGo fully supports the Go standard library on supported native platforms. CI requires compatibility coverage for every public package and exported symbol in the primary Go toolchain, and runs [`test/std`](test/std/README.md) with both supported toolchains.
 
-* [hello](_demo/hello/hello.go): call C `printf` to print `Hello world`
-* [concat](_demo/concat/concat.go): call C `fprintf` with `stderr`
-* [qsort](_demo/qsort/qsort.go): call C function with a callback (eg. `qsort`)
+Other targets may not provide every OS service or implementation-specific runtime behavior.
 
-To run these demos (If you haven't installed `llgo` yet, please refer to [How to install](#how-to-install)):

+| Embedded | [`-target`](doc/Embedded_Cmd.md) configurations for supported boards and MCUs, with selected QEMU/emulator smoke tests |

+* [hello](_demo/c/hello/hello.go): call C `printf` to print `Hello world`
+* [concat](_demo/c/concat/concat.go): call C `fprintf` with `stderr`
+* [qsort](_demo/c/qsort/qsort.go): call a C function that takes a callback (e.g. `qsort`)
+
+To run a demo (see [How to install](#how-to-install) if `llgo` isn't installed yet):
+
+```sh
+cd <demo-directory>  # e.g. cd _demo/c/hello
+llgo run .
+```
+
+### Other frequently used libraries
+
+Beyond the standard library, LLGo can import libraries from across the C/C++ ecosystem. Bindings are currently maintained by hand; automating this process, as is already done for Python library imports, is planned for the future.
+
+Available bindings include:
+
+* [c/bdwgc](https://pkg.go.dev/github.com/goplus/lib/c/bdwgc)

-## Other frequently used libraries
-
-LLGo can easily import any libraries from the C ecosystem. Currently, this import process is still manual, but in the future, it will be automated similar to Python library imports.
-
-The currently supported libraries include:
-
-* [c/bdwgc](https://pkg.go.dev/github.com/goplus/lib/c/bdwgc)

-
-
-## Go syntax support
-
-All Go syntax (including `cgo`) is already supported. Here are some examples:
-
-* [concat](_demo/concat/concat.go): define a variadic function
-* [genints](_demo/genints/genints.go): various forms of closure usage (including C function, recv.method and anonymous function)
-* [errors](_cmptest/errors/errors.go): demo to implement error interface
-* [defer](_cmptest/defer/defer.go): defer demo
-* [goroutine](_demo/goroutine/goroutine.go): goroutine demo
-
-
-### Defer
-
-LLGo `defer` does not support usage in loops. This is not a bug but a feature, because we think that using `defer` in a loop is a very unrecommended practice.
-
-
-### Garbage Collection (GC)
-
-By default, LLGo implements `gc` based on [bdwgc](https://www.hboehm.info/gc/) (also known as [libgc](https://www.hboehm.info/gc/)).
-
-However, you can disable gc by specifying the `nogc` tag. For example:
-
-```sh
-llgo run -tags nogc .
-```
-
-
-## Go packages support
-
-Here are the Go packages that can be imported correctly:
-
-* [unsafe](https://pkg.go.dev/unsafe)

 ## Key modules
 
 Below are the key modules for understanding the implementation principles of `llgo`:
 
-* [ssa](https://pkg.go.dev/github.com/goplus/llgo/ssa): It generates LLVM IR files (LLVM SSA) using the semantics (interfaces) of Go SSA. Although `LLVM SSA` and `Go SSA` are both IR languages, they work at completely different levels. `LLVM SSA` is closer to machine code, which abstracts different instruction sets. While `Go SSA` is closer to a high-level language. We can think of it as the instruction set of the `Go computer`. `llgo/ssa` is not just limited to the `llgo` compiler. If we view it as the high-level expressive power of `LLVM`, you'll find it very useful. Prior to `llgo/ssa`, you had to operate `LLVM` using machine code semantics. But now, with the advanced SSA form (in the semantics of Go SSA), you can conveniently utilize `LLVM`.
-* [cl](https://pkg.go.dev/github.com/goplus/llgo/cl): It is the core of the llgo compiler. It converts a Go package into LLVM IR files. It depends on `llgo/ssa`.
-* [internal/build](https://pkg.go.dev/github.com/goplus/llgo/internal/build): It strings together the entire compilation process of `llgo`. It depends on `llgo/ssa` and `llgo/cl`.

+## LLVM/Clang
+
+LLGo can download the Espressif-maintained ESP LLVM/Clang
+`19.1.2_20250905-3` toolchain on demand from
+[`goplus/espressif-llvm-project-prebuilt`](https://github.com/goplus/espressif-llvm-project-prebuilt/releases/tag/19.1.2_20250905-3).
+Current LLGo release archives also include this toolchain under
+`crosscompile/clang`, because the shipped `llgo` executable dynamically links
+its LLVM library.
+
+LLVM, Clang, LLD, libc++, libc++abi, libunwind, compiler-rt, and other
+LLVM-project components are licensed under Apache License 2.0 with LLVM
+Exceptions. The complete license is reproduced in
+[`LICENSES/XGo-LLVM-Apache-2.0-WITH-LLVM-exception.txt`](LICENSES/XGo-LLVM-Apache-2.0-WITH-LLVM-exception.txt).
+Archive extraction preserves upstream license files.
+
+## Components downloaded for cross-compilation
+
+LLGo downloads the following components directly from their upstream release
+locations when a selected target needs them. They are stored in the user's LLGo
+cache; they are not vendored in this source tree. Their license files remain in
+the extracted source or SDK directory.
+
+The Go packages under `internal/crosscompile/compile/libc` and
+`internal/crosscompile/compile/rtlib` are LLGo build manifests, not copies of
+the C library sources. The manifest code itself is compiled into `llgo` and is
+covered by LLGo's Apache-2.0 license. At cross-compilation time, those manifests
+select files from the downloaded picolibc, ESP newlib, or compiler-rt tree and
+build static archives in that same cached tree. The archives are then linked
+into the target program, so they are not part of the `llgo` executable or LLGo
+release archive, but their code can be incorporated into the resulting
+firmware.
+
+| Component | Download source | License location |
+| --- | --- | --- |
+| WASI SDK 25 | [`WebAssembly/wasi-sdk`](https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-25) | upstream `LICENSE` and license files in the SDK |
+| picolibc/newlib sources | [`goplus/picolibc`](https://github.com/goplus/picolibc) | upstream `COPYING.picolibc` and `COPYING.NEWLIB` |
+| ESP newlib sources | [`goplus/newlib`](https://github.com/goplus/newlib/tree/esp-4.3.0_20250211-patch7) | upstream `COPYING.NEWLIB` and applicable file notices |
+| compiler-rt sources | [`goplus/compiler-rt`](https://github.com/goplus/compiler-rt/tree/xtensa_release_19.1.2) | upstream `LICENSE.TXT` (Apache-2.0 WITH LLVM-exception) |
+
+Firmware or other binaries built from downloaded C library sources may carry
+their own redistribution requirements. Distributors of those outputs should
+retain the applicable license and copyright notices from the cached source;
+in particular, picolibc and ESP newlib use per-file notices collected by their
+upstream `COPYING` files.
+
+## External tools and system libraries
+
+BDWGC, OpenSSL, libffi, libuv, cJSON, SQLite, zlib, Python, Emscripten, QEMU,
+OpenOCD, flashing utilities, and platform SDK/system libraries are installed or
+provided separately. LLGo may link to or invoke them, but does not copy them
+into its source tree or release archives, except for LLVM-project components
+explicitly described above. Their upstream licenses therefore apply to the
+separate installations and to any redistributed output that incorporates them;
+they are not relicensed by LLGo.
+
+## Redistribution
+
+Distributions containing the source, the `llgo` executable, the bundled
+toolchain, or firmware linked with third-party runtime or target support must
+retain or reproduce the applicable copyright notices, license conditions,
+disclaimers, and NOTICE text described above.

+
+OPTIONS:
+    -h, --help      Show this help message and exit
+
+ARGUMENTS:
+    TEST_DIR        Required. The test directory containing main.go to build.
+                    Examples: empty, defer
+
+    TARGET_FILE     Optional. A text file containing target names, one per line.
+                    Lines starting with # are treated as comments and ignored.
+                    Empty lines are also ignored.
+
+BEHAVIOR:
+    Without TARGET_FILE:
+        - Automatically discovers all targets from ../../targets/*.json files
+        - Extracts target names from JSON filenames
+
+    With TARGET_FILE:
+        - Reads target names from the specified file
+        - Supports comments (lines starting with #)
+        - Ignores empty lines and whitespace
+
+IGNORED TARGETS:
+    The following targets are automatically ignored and not built:
+    atmega1280, atmega2560, atmega328p, atmega32u4, attiny85,
+    fe310, k210, riscv32, riscv64, rp2040
+
+RESULT CATEGORIES:
+    ✅ Successful: Build completed successfully
+    🔕 Ignored: Target is in the ignore list
+    ⚠️  Warned: Build failed with configuration warnings
+    ❌ Failed: Build failed with errors
+
+EXIT CODES:
+    0    All builds successful, ignored, or warned only
+    1    One or more builds failed with errors

-Usage: $(basename "$0") [OPTIONS] [TARGET_FILE]
-
-Build targets for llgo across multiple platforms.
-
-OPTIONS:
-    -h, --help      Show this help message and exit
-
-ARGUMENTS:
-    TARGET_FILE     Optional. A text file containing target names, one per line.
-                    Lines starting with # are treated as comments and ignored.
-                    Empty lines are also ignored.
-
-BEHAVIOR:
-    Without TARGET_FILE:
-        - Automatically discovers all targets from ../../targets/*.json files
-        - Extracts target names from JSON filenames
-
-    With TARGET_FILE:
-        - Reads target names from the specified file
-        - Supports comments (lines starting with #)
-        - Ignores empty lines and whitespace
-
-IGNORED TARGETS:
-    The following targets are automatically ignored and not built:
-    atmega1280, atmega2560, atmega328p, atmega32u4, attiny85,
-    fe310, k210, riscv32, riscv64, rp2040
-
-RESULT CATEGORIES:
-    ✅ Successful: Build completed successfully
-    🔕 Ignored: Target is in the ignore list
-    ⚠️  Warned: Build failed with configuration warnings
-    ❌ Failed: Build failed with errors
-
-EXIT CODES:
-    0    All builds successful, ignored, or warned only
-    1    One or more builds failed with errors
-
-EXAMPLES:
-    $(basename "$0")                    # Build all targets from JSON files
-    $(basename "$0") my-targets.txt     # Build targets from file

+# LLGo baseline benchmarks
+
+This suite is the lightweight performance gate for ordinary LLGo changes. It
+uses fixed workloads and short calibrated benchmarks on Linux and macOS so it
+can run on every `main` push and pull request. Branch-only series can be run
+explicitly with `workflow_dispatch`, avoiding duplicate push and pull-request
+jobs for the same commit. The two native jobs record normalized artifacts; a
+trusted `workflow_run` publisher validates and merges both platforms into one
+commit, branch, or pull-request series.
+
+The program workloads reuse:
+
+- `benchmark/binary_size/cprintf`: only `lib/c.Printf` (default and `-lto=full`);
+- `benchmark/binary_size/println`: only the built-in `println` (default and `-lto=full`);
+- `benchmark/binary_size/fmtprintf`: `fmt.Printf` (default and `-lto=full`).
+
+For each workload, the collector performs an unmeasured warm build, then records
+median build time, median process time, file size, executable-code bytes,
+allocated non-executable data, and zero-filled data. On ELF, read-only constants
+are included in the data bucket; on Mach-O, `__TEXT` constants are included in
+the text bucket. The Go benchmark stream records five samples of selected
+compiler helpers and LLGo-generated core-language operations: direct/interface
+calls, defer, goroutine creation, channels, `getg`, and global access.
+
+For pull requests, each platform job checks out the recorded base and current
+commits into the same source path, then runs both suites sequentially on the same
+runner. The pull request comment compares that pair, avoiding differences from
+runner machines and embedded source paths. Dependency setup is shared, and Go's
+build cache can be reused by unchanged packages; main pushes still run the suite
+only once. Very small changes can still be scheduler, frequency, or thermal
+noise and should be confirmed by repeated workflow runs. If a workflow does not
+provide a paired result, the publisher falls back to the latest matching `main`
+data.
+
+The trusted publisher commits the current result history and generated site to
+the `pages` branch of the configured data repository. Every LLGo repository
+defaults to `<owner>/llgo-benchmark-data`:
+
+```text
+llgo/baseline/series/main/main
+llgo/baseline/series/branch/<safe branch identifier>
+llgo/baseline/series/pull/<number>
+```
+
+The publisher never executes code from the measured revision and pull request
+jobs never receive the benchmark repository token. Pull requests receive one
+updated summary comment linking to their long-term trend page. If no matching
+`main` history exists yet, the pull-request report is still published and
+marks every metric as `new`.
+
+Local collection:
+
+```sh
+GOMAXPROCS=2 go build -o .benchmark/llgo ./cmd/llgo
+go run ./benchmark/baseline \
+  -llgo .benchmark/llgo \
+  -out .benchmark/results
+```
+
+Write the selected Go benchmark output to `.benchmark/results/go.txt`:
+
+```sh
+results=.benchmark/results/go.txt
+GOMAXPROCS=1 go test \
+  -run '^$' \
+  -bench '^(BenchmarkMergeCompilerFlags|BenchmarkMergeLinkerFlags|BenchmarkLookupPCRandom)$' \
+  -benchtime=250ms -count=5 -cpu=1 \
+  ./internal/clang ./internal/build/funcinfo | tee "$results"
+GOMAXPROCS=1 .benchmark/llgo test \
+  -run '^$' \
+  -bench '^(BenchmarkRuntimeGetG|BenchmarkGlobal(Read|Write)|Benchmark(DirectCall|InterfaceCall|Defer|ChannelBuffered|ChannelHandoff))$' \
+  -benchtime=250ms -count=5 \
+  ./test/llgoext | tee -a "$results"
+GOMAXPROCS=1 .benchmark/llgo test \
+  -run '^$' -bench '^BenchmarkGoroutine$' -benchtime=100x -count=5 \
+  ./test/llgoext | tee -a "$results"
+```
+
+Then validate and export the complete artifact in standard Go benchmark format:
+
+```sh
+go run ./benchmark/baseline \
+  -mode export \
+  -out .benchmark/results \
+  -benchmark-output .benchmark/results/benchmark.txt
+```

+# Binary size workloads
+
+These fixed programs keep LLGo binary-size measurements comparable across
+linker and PCLN packaging changes. The comprehensive linker/PCLN matrix is
+maintained by `xgo-dev/benchmarks`; `benchmark/baseline` reuses the three
+smallest workloads for the per-commit lightweight size and timing gate.
+
+- `cprintf`: the smallest C-library hello world, using only `lib/c.Printf`.
+- `println`: a hello world using the built-in `println`.
+- `fmtprintf`: a hello world using `fmt.Printf`.
+- `texttemplate`: a heavier standard-library program using `text/template`.
+- `nilfault`: an import-free abnormal path that dereferences a nil pointer.
+
+The first four programs must exit successfully with their expected output.
+`nilfault` must exit unsuccessfully with a nil-pointer diagnostic in every
+mode; for `external`, check it once with the sidecar present and once after the
+sidecar has been removed. The runtime integration suite separately verifies
+that a hardware-fault signal path never starts sidecar I/O.
+
+Size reports for `-pclntab=external` must record the executable and its
+`.pclntab` sidecar separately, with their sum shown explicitly. Run every
+linker/PCLN variant at the same output path: DWARF records paths, so changing
+the output path can otherwise make byte counts look different even when two
+flag combinations have equivalent code-generation semantics.
+
+This initial matrix applies to native Darwin/Linux executable builds;
+generation, archive/shared, and fixed-target policies are outside this
+benchmark.
+
+The initial comparison matrix is the Cartesian product of
+`embedded|external|none` and these linker groups: default, `-w`, `-s`, and
+`-s -w=false`. Until native symbol-table deletion is implemented, also assert
+that `-s` has the same byte counts as `-w`, and `-s -w=false` has the same byte
+counts as the default, when each pair uses the exact same output path.

+# Runtime Funcinfo Benchmark
+
+This benchmark keeps runtime funcinfo measurements comparable across branches by
+generating the same probe programs and rebuilding them with each compiler/root
+pair in one run.
+
+It covers:
+
+- hot runtime metadata calls: `Caller`, `Callers`, `CallersFrames`,
+  `FuncForPC`, and `Func.FileLine`.
+- deep stacks through direct calls, interface calls, and closures.
+- many packages and methods, generated from configurable package/method counts.
+- cold first-use runtime metadata paths, including lazy table initialization.
+- a stdlib-heavy program with `encoding/json`, `text/template`, `regexp`,
+  `go/parser`, `go/token`, and `net/netip` imports.
+- ordinary code (`plain`): pure-compute probes (recursive `fib`, JSON
+  round-trip, `sort.Ints`, map churn) with no runtime introspection at all,
+  measuring what the funcinfo machinery costs code that never asks for it.
+
+Generated modules use `example.com/llgo-bench/...` import paths. This is
+intentional: LLGo does not enable caller-frame tracking for stdlib-shaped paths
+without a dot, and that would benchmark the fallback path instead of normal
+third-party package behavior.
+
+Example:
+
+```sh
+go run ./benchmark/runtime_funcinfo \
+  -runs=11 \
+  -llgo-opt=2 \
+  -variant go=go \
+  -variant main=llgo,/path/to/llgo-main,/path/to/llgo-main-root \
+  -variant 2002=llgo,/path/to/llgo-2002,/path/to/llgo-2002-root \
+  -variant 2009=llgo,/path/to/llgo-2009,/path/to/llgo-2009-root \
+  -variant 2010=llgo,/path/to/llgo-2010,/path/to/llgo-2010-root
+```
+
+Add `-include-lto` to build an additional `+lto` variant for every LLGo
+compiler. LLGo builds use `-O2` by default; pass `-llgo-opt=` to omit the
+optimization flag. Add `-scales=6x6,12x12,24x24` to generate separate
+`multipkg_*` and `cold_*` scenarios for several package/function counts in one
+run. Output is written to `benchmark/runtime_funcinfo/out` by default:
+
+- `summary.md`: markdown performance and size tables.
+- `results.json`: raw build and run data.
+- `work/`: generated probe modules.
+- `bin/`: generated executables.
+
+Performance cells are `best/trimmed avg` from process-level runs. The trimmed
+average drops one minimum and one maximum when at least three runs are present.
+`-iters` is a base iteration count: `hot` uses the full count, `deep` uses a
+quarter, `multipkg`/`stdlib` use one twentieth, and `plain` uses 1/2000
+because each operation does substantially more work.
+
+`multipkg.FuncForPCMany` and `multipkg.FileLineMany` are batch metrics over all
+generated target functions (`-packages * -methods`, 144 targets with the default
+settings), not single-lookup timings.
+
+`cold.First*` metrics are single measurements from a fresh process and include
+lazy runtime initialization that has not already happened in that process.
+`cold.WarmFuncForPCMany` and `cold.WarmFileLineMany` use the same batch target
+count as `multipkg`.

+## LLGo Plugin of LLDB
+
+### Build with debug info
+
+```shell
+llgo build -O0 -ldflags=-w=false -o cl/_testdata/debug/out ./cl/_testdata/debug
+```
+
+LLGo temporarily omits DWARF when `-w` is absent because the current debug
+information path is not yet safe for broad use. The native executable build
+above explicitly uses `-ldflags=-w=false` to enable DWARF. Use
+`-ldflags=-w` to explicitly omit it. `-O0` is recommended for the most
+complete local variable inspection in LLDB. The former `LLGO_DEBUG` and
+`LLGO_DEBUG_SYMBOLS` environment variables are no longer read. This uses
+LLGo's existing runnable DWARF path; improving its metadata quality and making
+it optimization-independent are separate follow-up work.
+
+LLGo currently marks compile units as `DW_LANG_C` because stock LLDB does not
+provide a Go language plugin and otherwise hides valid frame variables.
+`DW_AT_producer` remains `LLGo`, and a versioned debugger marker lets this
+plugin distinguish LLGo binaries from ordinary C targets. Upstream LLDB
+requires an RFC and a long-term maintainer before restoring native Go language
+support, so LLGo keeps its language-specific adapter external; the decision is
+recorded in [issue #2154](https://github.com/xgo-dev/llgo/issues/2154).
+
+### Debug with lldb
+
+```shell
+llgo lldb ./cl/_testdata/debug/out
+```
+
+Use `-lldb` or `LLGO_LLDB` to select a particular LLDB 18+ executable. Arguments
+after the LLGo flags are passed through to LLDB; use `--` when the first LLDB
+argument begins with `-`:
+
+```shell
+llgo lldb -lldb /opt/homebrew/bin/lldb -- --batch ./cl/_testdata/debug/out
+```
+
+The command embeds and loads the LLGo Python adapter, so an installed `llgo`
+does not depend on a source checkout. `cmd/llgo/lldbtest/runlldb.sh` remains as
+a thin compatibility wrapper. Adapter commands live under `llgo`, including
+`llgo status`, `llgo print`, and `llgo vars`; stock LLDB commands and aliases
+such as `p` and `v` are left unchanged. `llgo status` reports the recognized
+debugger schema, runtime-layout version, target triple, pointer size, and byte
+order. Unknown marker versions disable only the LLGo-specific commands; raw
+LLDB debugging remains available.
+
+For recognized LLGo targets, the adapter also gives strings length-bounded
+quoted summaries and slices `len`/`cap` summaries with indexed synthetic
+children. These views cover named string and slice types as well as the
+predeclared types. Explicit `llgo print` slice views respect LLDB's
+`target.max-children-count` setting. Ordinary C targets and targets with
+unknown or ambiguous LLGo markers retain LLDB's raw presentation.
+
+The integration fixture follows LLDB's API-test style: `main.go` marks
+executable breakpoint lines with `LLDB_BREAK`, while `test.py` keeps the
+expected variables and values in an explicit SB API test table. Assertions are
+not parsed from source comments.

+# Dev tooling
+
+This directory contains scripts for running LLGo locally and inside reusable Linux dev containers.
+
+## Prerequisites
+
+- Docker installed and running
+- Docker Compose v2 (`docker compose`, not `docker-compose`)
+
+## 1) Start a Linux container, then run `dev/llgo.sh` / `dev/llgo_wasm.sh`
+
+Start an interactive shell (pick one):
+
+```bash
+./dev/docker.sh amd64
+./dev/docker.sh arm64
+./dev/docker.sh i386
+```
+
+Notes:
+- `amd64` uses the `pydeps` image target (includes extra Python demo deps like `numpy`/`torch`).
+- `arm64` and `i386` use the smaller `base` target (no extra Python ML deps).
+
+Inside the container, run tests/builds using the repo scripts:
+
+```bash
+./dev/llgo.sh test ./...
+./dev/llgo.sh test ./test
+
+# WASI/WASM (wasip1/wasm)
+./dev/llgo_wasm.sh build ./...
+```
+
+Notes:
+- `dev/docker.sh` starts in the same repo subdirectory you launched it from.
+- `dev/llgo.sh` and `dev/llgo_wasm.sh` must be run from within `LLGO_ROOT` (the repo) and will error otherwise.
+
+## 2) Start a Linux container, run one command, then exit
+
+```bash
+./dev/docker.sh amd64 bash -lc './dev/llgo.sh test ./test'
+```
+
+## 3) Run on the host (no container)
+
+From anywhere inside the repo:
+
+```bash
+./dev/llgo.sh test ./test
+./dev/llgo_wasm.sh build ./...
+```
+
+## 4) Run local CI (covers most checks)
+
+```bash
+./dev/local_ci.sh
+```
+
+This script creates a temporary workspace, runs formatting/build/tests, runs `llgo test`, and then runs demo checks.
+You can control demo parallelism via `LLGO_DEMO_JOBS` (defaults to up to 4 jobs).
+
+## 5) `dev/docker.sh` (composition-friendly)
+
+`dev/docker.sh` is a thin wrapper around `docker compose`:
+
+```bash
+./dev/docker.sh <arch> [command...]
+```
+
+- `<arch>` must be `amd64`, `arm64`, or `i386`.
+- If `[command...]` is omitted, it starts an interactive `bash`.
+- If `[command...]` is provided, it runs that command and exits.
+- You must run it from within the repo (within `LLGO_ROOT`), and it will start in the matching repo subdirectory inside the container.
+
+## 6) Refresh test goldens
+
+LLGo has separate refresh flows for runtime data and LLVM IR checks:
+
+- `gentests` for runtime-output and package-metadata golden files
+- `litgen` for the curated set of source-embedded, autogenerated `// LITTEST`
+  FileCheck snapshots
+
+### `gentests`
+
+Run:
+
+```bash
+go run ./chore/gentests
+```
+
+Behavior:
+
+- Refreshes `expect.txt` for the built-in runtime test suites using the existing execution flow.
+- Refreshes `meta-expect.txt` for package-metadata tests.
+- Preserves the runtime-output skip convention where `expect.txt` containing only `;` means "do not refresh".
+
+LLVM IR is not part of the `gentests` workflow; it is checked from the marked
+Go source with FileCheck.
+
+### `litgen`
+
+Autogenerated checks stay in the Go source file. A test opts in with an
+autogenerated note immediately after `// LITTEST`; the note also records the
+arguments required to reproduce the checks:
+
+```go
+// LITTEST
+// NOTE: Assertions have been autogenerated by chore/litgen UTC_ARGS: --function=run --check-globals=smart
+```
+
+Create or replace an autogenerated region explicitly:
+
+```bash
+go run ./chore/litgen --function=run --check-globals=smart path/to/in.go
+```
+
+Refresh existing autogenerated tests recursively, using the arguments recorded
+in each source file:
+
+```bash
+go run ./chore/litgen -u cl
+```
+
+Check that committed autogenerated checks are current without modifying files:
+
+```bash
+go run ./chore/litgen -u --check cl
+```
+
+Behavior:
+
+- Accepts one or more paths.
+- If the path is a `.go` file, it refreshes only that file. The file must start with `// LITTEST`.
+- If the path is a directory, it walks that directory recursively and processes marked source files in a stable order.
+- `-u`/`--update-only` updates only tests that already carry the autogenerated note. Handwritten checks are never silently replaced.
+- `--check` reports stale autogenerated checks and does not write files.
+- `--function` is repeatable and selects functions by regular expression. Use
+  `--all-functions` only when the entire generated module is genuinely the test
+  contract.
+- `--check-globals=none|smart|all` controls global checks. `smart` keeps globals
+  referenced by selected functions.
+- Generated checks abstract numeric LLVM SSA values, block suffixes, numeric
+  globals, and generated cgo symbol hashes to reduce irrelevant churn.
+- Does not update runtime-output or package-metadata goldens.
+
+Use `litgen` only when a test intentionally checks a broad IR shape. Prefer
+short, handwritten FileCheck assertions for a single lowering or ABI property.
+Runtime output does not replace focused IR checks; it only removes the need for
+a second full-output snapshot.
+
+Use 100 FileCheck directive lines as an audit threshold rather than a size cap.
+For a larger handwritten fixture, every group should correspond to an explicit
+semantic contract. Convert long contiguous IR-shape checks to an opted-in
+`litgen` snapshot instead.
+
+### Marker convention
+
+Source-embedded IR checks are enabled by putting this marker on the first line of the source file:
+
+```go
+// LITTEST
+```
+
+The generated directives are consumed by the existing `littest`/FileCheck path in the compiler tests.
+
+The plain marker retains the existing IR stage for the fixture's effective
+target. To check that stage for several platforms independently of the host,
+list a cross-compilation matrix explicitly:
+
+```go
+// LITTEST darwin/arm64 linux/amd64
+```
+
+The harness generates IR once for every listed GOOS/GOARCH pair and enables
+`CHECK` together with the corresponding architecture and specific prefixes,
+such as `CHECK,ARM64,DARWIN-ARM64` or `CHECK,AMD64,LINUX-AMD64`. Keep portable
+assertions under `CHECK`, assertions shared by an architecture under `ARM64`,
+`AMD64`, and similar prefixes, and only OS-specific differences under the exact
+target prefix. Do not hide known platform differences in regular-expression
+alternatives.
+
+The fixture's current effective target is always checked as well. Targets on
+the marker add cross-compilation coverage rather than replacing the platform
+running the test, and a listed target equal to the current target is
+deduplicated. An unlisted CI platform therefore still exercises all portable
+`CHECK` assertions; add its explicit prefix when it has a distinct IR contract.
+
+A test can instead check the module after target ABI lowering and before LLVM
+optimization:
+
+```go
+// LITTEST: POST-ABI
+```
+
+Without an autogenerated note, post-ABI checks remain handwritten and
+`litgen -u` leaves them untouched.
+
+A post-ABI fixture can request several GOOS/GOARCH configurations on the same
+marker. The harness generates IR once per listed target while the target
+prefixes keep the differing assertions in one file. Runtime output, when
+present, is still executed once with the fixture's normal run configuration.
+
+```go
+// LITTEST: POST-ABI linux/amd64 linux/arm64
+```
+
+To opt a post-ABI target matrix into automatic maintenance, add the same
+autogenerated note used by an ordinary fixture. Automatic post-ABI
+generation requires at least one explicit GOOS/GOARCH target on the marker so
+the result is reproducible. For either matrix stage, `litgen` generates each
+requested target, emits identical directives as shared `CHECK` lines, and keeps
+same-architecture directives under the GOARCH prefix. Only remaining
+differences use exact target prefixes.
+
+```go
+// LITTEST: POST-ABI linux/amd64 linux/arm64
+// NOTE: Assertions have been autogenerated by chore/litgen UTC_ARGS: --function=f32ToI32 --check-globals=none
+```
+
+Cross-target IR generation does not require running target binaries. A fixture
+that imports `C`, directly or through a dependency, is the exception: cgo also
+needs a target C compiler, headers, and sysroot. Keep such fixtures on plain
+`// LITTEST` unless the test environment supplies that complete cross-cgo
+toolchain; their explicit target-prefixed assertions are then exercised by the
+matching platform CI.
+
+Example:
+
+- [cl/_testrt/litdemo/in.go](../cl/_testrt/litdemo/in.go) is a minimal `_testrt` case that demonstrates `litgen` output.
+- [cl/_testlibc/setjmp/in.go](../cl/_testlibc/setjmp/in.go) demonstrates a handwritten default-stage cross-target matrix.
+- [cl/_testgo/postabi/in.go](../cl/_testgo/postabi/in.go) demonstrates a handwritten post-ABI check with shared assertions and target-specific prefixes.
+- [cl/_testdata/floatint/in.go](../cl/_testdata/floatint/in.go) demonstrates an automatically maintained post-ABI target matrix.

+# Closure ABI
+
+This document records the phase-one design from
+[proposal #2170](https://github.com/xgo-dev/llgo/issues/2170).
+
+## Decisions
+
+- Keep the existing two-word function value: `{fn, env}`. This change does not
+  add flags or switch to Go's one-pointer funcval layout.
+- A Go/go-types function signature never contains an environment parameter.
+  `llssa.Function` records independently whether its physical entry needs env.
+- Plain Go functions and C functions use `{real entry, nil}`. Closures and
+  bound method wrappers use `{real entry, non-nil env}`.
+- `env == nil` means that the physical entry has no env parameter. A source
+  closure whose captures are all zero-sized is reclassified as a no-env entry;
+  it recreates their permitted shared non-nil address from the module sentinel.
+  Other required environments never use nil. A nil pointer receiver method
+  value is represented by an allocated environment cell, and an interface
+  method value captures the complete interface state.
+- A statically known call uses the entry's `NeedsEnv` property. An
+  explicit-context dynamic funcval call (including WebAssembly) branches once
+  on `env != nil` and emits two exact LLVM call edges: `fn(args...)` and
+  `fn(env, args...)`.
+- Native hidden env parameters use LLVM `nest` or `swiftself` parameter
+  attributes. WebAssembly and architectures without a validated LLVM
+  hidden-register mapping use an explicit physical env parameter, but only on
+  env-bearing entries.
+- Direct interface invocation remains a transient `(method entry, receiver)`
+  operation. Its receiver is an ordinary ABI argument; first-class interface
+  method values are lowered through the normal bound-wrapper closure path.
+- Function values point directly at their physical entries; closure calls do
+  not add a generated adapter layer. C function values point directly at the C
+  entry.
+- PCLN metadata remains function-centric. A compiler-generated wrapper or
+  adapter, if one is needed for another purpose, is an ordinary function with
+  its own function record; closure environment transport is not part of PCLN.
+
+Native dynamic calls always use one hidden-env call edge, including when env is
+nil. An optimizer barrier keeps the indirect code pointer opaque: LLVM IR
+considers `R(ptr nest, args...)` and `R(args...)` different prototypes and must
+not devirtualize a plain entry into the hidden-env call edge. The barrier emits
+no machine instruction.
+
+The backend selects this ABI from the resolved LLVM target triple, not from
+`GOARCH`. `GOOS/GOARCH` select Go source files and type sizes, but named targets
+may intentionally reuse a compatible Go architecture: for example,
+`wasm-unknown`, `wasip2`, Xtensa, AVR, and some RISC-V targets use `GOARCH=arm`
+while emitting a different physical architecture. The triple is what LLVM uses
+to assign `nest`/`swiftself` registers.
+
+## Physical entry ABI
+
+An env-bearing entry is created from the semantic signature plus one backend
+parameter:
+
+```text
+semantic:  R func(A, B)
+physical:  R entry(env, A, B)
+```
+
+The physical env parameter is:
+
+- `nest` on validated x86, RISC-V, and AArch64 platforms where X18 is
+  available;
+- `swiftself` on ARM and platforms where AArch64 X18 is reserved;
+- an ordinary leading parameter on the explicit fallback.
+
+Windows follows the architecture-selected ABI even though LLGo does not yet
+support the OS: x86 uses `nest`, while ARM/AArch64 use `swiftself`. The x86
+libffi Go ABI already matches LLVM `nest`; the Windows ARM/AArch64 public-FFI
+final hop remains a TODO. This keeps compiled closure entries independent of
+when runtime support is added.
+
+WebAssembly remains explicit because it has no compatible hidden-register
+transport. Adding one in the future is a deliberate target ABI upgrade.
+
+LLVM parameter attributes are preserved when LLGo rewrites large aggregate
+returns or lowers its C ABI.
+
+## FFI and reflection
+
+`reflect.Value.Call` starts from the semantic libffi signature:
+
+- explicit env target: add the env type/value only when `env != nil`; otherwise
+  use the semantic signature. This is the only `env != nil` decision in the
+  reflection/FFI path;
+- native hidden env target: x86, RISC-V, and AArch64 targets where X18 is
+  available use libffi's `ffi_call_go` directly when libffi exposes that API,
+  because its static-chain register is LLGo's `nest` register. ARM also uses
+  `ffi_call_go`; a short final-hop bridge moves libffi's IP/R12 context to
+  `swiftself`/R10 without saving argument registers or using TLS. LLVM lowers
+  ARM32 `nest` as an ordinary leading argument rather than a hidden static
+  chain, so it cannot replace this `swiftself` bridge.
+- x86 libffi builds without `FFI_GO_CLOSURES`, including Apple SDK libffi, use
+  stock `ffi_call` plus the TLS final-hop trampoline, which installs LLVM's
+  `nest` register before entering the real target.
+- Apple/Android AArch64 use stock `ffi_call` plus the TLS final-hop trampoline:
+  libffi's Go ABI uses X18 while LLGo's entry ABI uses `swiftself`/X20, so the
+  public `ffi_call` path needs TLS to carry `{fn, env}` to its final target.
+
+The build obtains both headers and linker flags from `pkg-config libffi`; no
+Homebrew-specific libffi path is required. Apple AArch64 remains on the X20 TLS
+trampoline because libffi's Go ABI uses X18 while LLGo's selected entry ABI
+uses `swiftself`/X20 there.
+
+Every architecture that selects a hidden env must select exactly one native
+FFI final hop: direct `ffi_call_go`, `ffi_call_go` plus a register bridge, or
+public `ffi_call` plus a TLS trampoline. The wrapper rejects missing or
+ambiguous selections at compile time.
+
+Bridge calls are balanced: their targets must return normally through the
+final hop so saved registers and, where used, the prior TLS context are
+restored.
+
+Although libffi's C implementation of `ffi_call_go` is a thin wrapper, it calls
+an architecture-private `ffi_call_int(..., closure)` and matching assembly; it
+cannot be reproduced outside libffi by wrapping public `ffi_call` alone. The
+compile-time direct path and the public-API fallback require neither a patched
+libffi nor rebuilding it. AArch64 libffi's Go ABI writes X18, so Apple/Android
+`swiftself`/X20 deliberately uses the public-call fallback. `reflect.MakeFunc`
+remains a normal libffi C closure: its funcval has `env == nil`, while libffi
+userdata owns the callback state separately.
+
+## Scope
+
+This phase includes closure creation/calls, method values, C function values,
+ABI rewriting, reflection, FFI, and direct-entry function values.
+
+It deliberately excludes:
+
+- a WebAssembly TLS/mutable-global optimization for `g.ctxt`;
+- flags or a future one-pointer funcval representation.

+# Defer Locality and GC Integration
+
+## Background
+
+`defer` chains belong to the current goroutine, and unwind paths must locate the
+active `*runtime.Defer`. A raw pointer stored only in pthread TLS is invisible to
+the Boehm collector. In stress scenarios—e.g. `TestDeferLoopStress` with
+1,000,000 defers—the collector could reclaim defer nodes, leaving dangling
+pointers and causing crashes inside deferred closures.
+
+Prior experiments (`test-defer-dont-free` branch) confirmed the crash disappeared when allocations bypassed GC (plain `malloc` without `free`), pointing to a root-registration gap rather than logical corruption.
+
+## Current Design
+
+1. **Runtime-owned goroutine state**
+   - Each `runtimeContext` owns its `g`, `m`, and `p`; `g.defer_` is the current
+     goroutine's defer-chain head.
+   - The context is allocated with `AllocRoot`, so pointers reachable through
+     `g` remain visible to the collector.
+   - A pointer-free `//llgo:tls` `uintptr` slot locates the current `g`. The
+     slot is only an address cache; the `runtimeContext` allocation is the GC
+     root.
+   - Bare-metal targets keep the same state in ordinary globals because they
+     have one execution context and their LLVM backends do not support native
+     TLS relocations.
+   - Runtime-created threads release that root in `mexit`. A pthread key remains
+     only as a thread-exit destructor sidecar for main and foreign threads; the
+     current-G read path does not call `pthread_getspecific`.
+
+2. **SSA codegen synchronization**
+   - `ssa/eh.go` calls `runtime.SetThreadDefer` whenever it updates the current
+     goroutine's defer head (on first allocation and when restoring the
+     previous link during unwind).
+   - Defer argument nodes and the `runtime.Defer` struct itself are allocated with `aggregateAllocU`, ensuring new memory comes from GC-managed heaps, and nodes are released via `runtime.FreeDeferNode`.
+
+3. **Locality directives**
+   - Runtime state that belongs to a logical goroutine uses `//llgo:gls`.
+   - Physical scheduler and execution-resource slots that must be available
+     before goroutine-local context setup use `//llgo:tls`.
+   - TLS and GLS currently share one physical owner because LLGo binds one
+     goroutine/P/M to one OS thread. The directive still records the intended
+     lifetime so a future scheduler can keep GLS with a migrating goroutine
+     while TLS remains with the thread.
+   - Pointer-bearing locality variables are kept in the GC-rooted locality
+     package payload rather than bespoke pthread-key allocations.
+   - Bare-metal builds use ordinary globals for the caller and FIPS state:
+     they have one logical context. This is an implementation fallback because
+     the current GLS package-block accessor still uses a native TLS address
+     cache, which those LLVM targets cannot lower.
+
+4. **Dynamic `sync.Pool` state**
+   - `sync.Pool` retains the GC-aware `clite/tls` handle. Each `Pool` needs a
+     dynamically allocated per-thread slot, while locality directives declare
+     a fixed set of static package variables.
+   - Keeping the handle preserves the existing atomic hot path, thread-exit
+     victim handoff, and cross-thread access to that victim. A static TLS map
+     would add an explicit never-pruned `*Pool` key set and a map lookup to
+     every `Get` and `Put`.
+   - The existing dynamic handle can itself retain state until thread exit;
+     matching upstream's GC-cycle pool cleanup would require a separate runtime
+     integration. This migration deliberately preserves the baseline behavior
+     instead of introducing a new retention mechanism.
+   - This cache has per-P/execution-resource lifetime, not goroutine lifetime;
+     dynamic TLS is correct for the current 1:1 P/M/thread model. Fully modeling
+     a scheduler that can move P between M would require a dynamic P-local
+     facility rather than GLS.
+
+5. **Non-GC builds**
+   - `FreeDeferNode` continues to release nodes via `c.Free` when building with
+     `-tags nogc`.
+
+## Testing
+
+Run the stress and regression suites to validate the integration:
+
+```sh
+./dev/llgo.sh test ./test -run TestDeferLoopStress
+./dev/llgo.sh test ./test
+```
+
+The updated `TestDeferLoopStress` now asserts 1,000,000 loop defers execute without failure, catching regressions in GC root tracking.

+# Link-phase ftab/findfunctab generation
+
+Status: design + staged plan. Depends on #2012 (runtime funcinfo find index)
+and benefits from #2015 (nanosecond monotonic clock, for honest benchmarks).
+
+## Problem
+
+#2012 builds the sorted function-entry table and the Go-style findfunctab at
+**first use in the running process**, because LLVM IR generation does not know
+final linked text order. This leaves four measured gaps against Go 1.26:
+
+1. `cold.FirstFuncForPC`: 36µs on macOS / 12µs on Linux vs Go's 2.4µs / 375ns.
+   The cold fast path (bounded linear scan of raw entry sections, then dladdr)
+   is a transitional mechanism; Go needs none of it because the linker ships a
+   sorted table.
+2. LTO inlining duplicates the body-embedded entry-site inline asm into every
+   inline site: `llgo_funcinfo_entry` grew ~4x on the multipkg benchmark and
+   host-function PCs get registered under the inlinee's symbol ID. IR-level
+   fixes were tried and ruled out (see Facts below); dedup must happen after
+   final code generation.
+3. The runtime keeps ~300 lines of transitional complexity: cold lookup
+   budget, section scans, first-use sort, entry-PC slack matching.
+4. pcvalue-style instruction-level line tables (the next alignment step with
+   Go) need a per-function table keyed by final text order.
+
+## Approach: post-link table generation
+
+Insert a post-link step into `internal/build` after the final clang/lld link:
+
+```
+link -> post-link tool: parse binary -> sort/dedup -> build buckets -> write back
+```
+
+A separate linker plugin was considered and rejected: llgo drives stock
+clang/lld and a plugin would need to be maintained per linker flavor
+(ld64.lld, ld.lld) and per LTO mode. Editing the linked artifact is
+linker-agnostic.
+
+### Function identity contract
+
+PCLN is indexed by physical text functions, following Go's linker model.
+Source functions and compiler-generated wrappers or adapters all contribute
+ordinary function records and entry sites. The symbol names the physical
+function; its display name may describe the corresponding Go operation.
+Calling conventions, closure environments, and their transport mechanism are
+not PCLN properties and must not introduce function-class-specific sections.
+
+### Data flow
+
+1. **Parse** the linked binary's metadata sections (`debug/elf`,
+   `debug/macho` from the Go stdlib — the tool runs on the host):
+   - `llgo_funcinfo_entry` / `__DATA,__llgo_fie` (Mach-O without physical
+     compaction) / `__LLGO,__llgo_fie` (embedded executable LTO Mach-O):
+     `{pc, symbolID}` records.
+   - Zero records are skipped, as in the runtime today.
+2. **Dedup by symbolID**: LTO inline copies register the same symbolID at
+   several PCs. The true entry is the record whose PC lies inside the text
+   range of the symbol that owns the symbolID; resolve via the binary's
+   symbol table (`.symtab` / `nlist`). Records that fall inside a different
+   function's range are inline copies — drop them. This is the fix for gap 2
+   that IR-level metadata could not express.
+3. **Sort** by PC; append a sentinel entry (end of text) so the runtime can
+   use Go's forward-scan lookup shape (`internal/pclntab.LookupFuncIndex`).
+4. **Build buckets** with `internal/pclntab.BuildFindFuncBuckets` — the
+   faithful port of `cmd/link`'s algorithm that has been sitting unwired
+   since #2012. Delta overflow is a hard error here, mirroring Go's linker;
+   if it ever fires, fall back to leaving the prebuilt table absent.
+5. **Write back and compact** the entry carrier:
+   - The compact table replaces the prefix of `llgo_funcinfo_entry`; if it
+     does not fit, the binary is left unchanged and the runtime uses its
+     first-use construction fallback.
+   - Embedded executable LTO Mach-O puts the entry carrier in a dedicated
+     `__LLGO` segment. Non-LTO, external-PCLN, c-shared, and c-archive Mach-O
+     keep it in `__DATA`: without a physical post-link compaction step, an
+     isolated carrier makes arm64 output pay for an otherwise-unused 16 KiB
+     file page. ELF links the carrier immediately before `.bss`, at the
+     file-backed tail of the final writable `PT_LOAD`. PC-line sites remain
+     outside the disposable range.
+   - ELF compaction rejects an image with a program segment after the carrier;
+     only non-loaded sections and the section-header table may be shifted.
+   - After fixing Mach-O chained pointers, section sizes, load commands,
+     segment offsets, ELF program/section headers, and link-edit offsets, the
+     tool removes the unused carrier suffix from the physical file. Virtual
+     addresses of program text/data do not move; the omitted tail becomes
+     zero-fill memory.
+   - Rewriting is transactional: construct and reopen the complete staged
+     image, re-sign an originally signed Mach-O, then atomically rename it.
+     An unfamiliar segment shape, overlapping relocation/fixup range, signing
+     failure, or verification failure leaves the original executable intact.
+
+### ASLR
+
+Stored table entries are offsets from the first function PC. The header keeps
+that base as a runtime address: Mach-O rewrites its slot into the dyld chained
+fixup chain, while supported non-PIE ELF outputs already use their runtime
+address. The lookup hot path therefore only adds the stored entry offset.
+
+### Runtime integration
+
+`initRuntimeFuncPCFramesOnce` gains a fast path: if the prebuilt header is
+valid, adopt the table directly (no section scan, no sort, no bucket build)
+— `FirstFuncForPC` becomes bucket-lookup cost, matching Go's shape. The
+existing first-use construction remains as the fallback whenever the header
+is invalid (older compilers, exotic formats, overflow bail-out), so the
+change is strictly additive and safe to land incrementally.
+
+## Staging
+
+- **P1** `chore/pclnpost`: standalone tool, parse + dedup + sort + bucket
+  build + stats printing; golden tests against binaries produced by the
+  existing test programs. No behavior change.
+- **P2** Reserve the section in `internal/build`, run the tool as a post-link
+  step, wire the runtime fast path. Benchmarks: cold.FirstFuncForPC on both
+  platforms; assert `llgo funcinfo: ... entries= prebuilt` via
+  LLGO_FUNCINFO_DEBUG.
+- **P3** (done) Mach-O bind-record resolution: pointer slots naming exported
+  Go functions are chained-fixup BIND nodes, not rebases; without decoding
+  them through the imports table, exported records miss the prebuilt ftab and
+  `FuncForPC` silently pays a dladdr per fresh pc (~6µs). Also: the prebuilt
+  header's base slot is spliced back into the fixup chain as a live rebase
+  node, so the runtime reads a dyld-slid runtime PC directly (no slide
+  arithmetic). Transitional cold budget/scan stays as the fallback for
+  non-rewritten binaries.
+- **P4** pcvalue-style line tables keyed by the prebuilt function order
+  (replaces the call-site pcline records; gives instruction-level FileLine).
+
+## Established facts (verified in #2012 work; do not re-derive)
+
+- Mach-O metadata sections need `live_support` + one lowercase-`l`
+  linker-private symbol per record; ld64/lld `-dead_strip` then drops records
+  exactly with their function. Verified with lld 19.1.7, including LTO.
+- Boundary symbols: ELF `__start_/__stop_`; Mach-O `section$start$SEG$SECT`
+  referenced from IR needs the `\x01` verbatim-name prefix or LLVM prepends
+  an underscore and the linker stops recognizing it.
+- Visible (non-`L`) labels inside Mach-O function bodies split the function
+  into atoms that the linker may reorder — assembler-local labels only.
+- `!associated` affects only linker GC; IR-level GlobalDCE deletes such
+  globals regardless, and `llvm.compiler.used` pins dead functions through
+  the records' initializers. This is why records stay body-embedded inline
+  asm and dedup happens post-link.
+- Mach-O chained fixups encode anchors to exported symbols as BIND nodes
+  (import ordinal + addend), even when the target is defined in the same
+  image; only local-symbol anchors are rebases. Decode both.
+- Adding fixup nodes does not pre-touch pages at load on modern macOS:
+  dyld uses page-in linking (the kernel applies fixups lazily at first
+  touch), so "sacrificial fixups to warm the table's pages" is not a
+  viable optimization — measured no effect on first-lookup latency.
+- `internal/pclntab` is a faithful port of Go 1.26's findfunctab generation
+  and lookup (uint8 deltas, overflow error, forward scan, sentinel); the
+  runtime's in-process variant deliberately uses uint16 deltas because LLGo
+  lacks Go's MINFUNC guarantee. The post-link table can use the faithful
+  uint8 layout since dedup restores the one-record-per-function invariant.

+# PCLN metadata packaging
+
+Status: initial implementation. This design is stacked on the typed Go linker
+options introduced by #2113.
+
+## Goals
+
+LLGo supports three independent packaging policies for the runtime function
+and line metadata used by `runtime.Caller`, `runtime.Callers`,
+`runtime.FuncForPC`, and stack traces or pprof symbolization on the available
+unwinding paths:
+
+- `-pclntab=embedded` keeps the metadata in the executable. This is the
+  default and preserves existing behavior.
+- `-pclntab=external` writes `<executable>.pclntab`. The executable loads that
+  optional file on the first safe symbolization request. A missing, stale, or
+  corrupt file is a cached soft failure; the program continues with the
+  available native fallback.
+- `-pclntab=none` does not generate the metadata and does not link the external
+  loader or its path/probe code.
+
+`-pclntab=external` is initially supported only for native executable builds
+without `-target` on Darwin/Linux amd64/arm64. `ModeGen`, `c-archive`,
+`c-shared`, named targets, and other OS/architecture combinations reject it.
+
+The policy is deliberately separate from Go's `-ldflags=-s` and `-w`:
+
+- LLGo temporarily omits DWARF by default because the existing DI path is not
+  yet safe for broad use. `-w=false` explicitly enables it; `-w` explicitly
+  omits it.
+- `-s` records native symbol-table omission intent and implies `-w` unless
+  `-w` is explicitly set; the explicit `-w` value wins regardless of argument
+  order. Native symbol-table deletion remains a later phase.
+- `-pclntab` controls LLGo runtime symbolization metadata.
+
+The explicit `-w` semantics above are Go-compatible, but the temporary
+DWARF-free default is not: Go behaves as if `-w=false` when the flag is absent.
+LLGo currently behaves as if `-w=true`; explicit `-w=false` overrides that
+default. Once the dedicated DI fixes make broad DWARF use safe, the default can
+be changed without changing flag parsing or backend precedence.
+
+`ModeGen` remains DWARF-free by default and emits DWARF only when `-w=false`
+is explicitly requested and supported.
+Effective DWARF omission (`-w`, or bare `-s`) is rejected for `c-archive` and
+`c-shared`. Fixed targets that always omit DWARF reject `-w=false`, while
+backends without an omit capability reject `-w`. Because native `-s`
+stripping is not implemented yet, `-s -w=false` does not strip shared or
+archive outputs.
+
+The former `LLGO_DEBUG` and `LLGO_DEBUG_SYMBOLS` environment switches are not
+part of this policy. Use `-w=false` to retain DWARF, `-w` to omit it,
+and `-O0` when a debugger-friendly unoptimized build is required.
+
+This change deliberately reuses LLGo's existing runnable DWARF path; it does
+not repair or redesign the debug metadata implementation. That path currently
+disables LLGo's LLVM and C ABI optimization steps while emitting DWARF, so
+`-w` can still affect optimization in addition to artifact metadata. Go's
+optimization-independent DWARF behavior requires a separate implementation
+PR and is explicitly out of scope here.
+
+Broad CI uses the DWARF-free default until the corresponding DI limitations
+are fixed. Targeted native integration, the debug IR fixture, and the full
+LLDB suite explicitly select `-w=false` to protect the currently supported
+runnable path.
+
+Consequently all combinations are meaningful. For example,
+`-ldflags=-s -pclntab=embedded` keeps Go-compatible runtime symbolization,
+while `-ldflags=-s -pclntab=external` keeps it in an optional deployment
+artifact.
+
+## Package boundaries
+
+Go-compatible build syntax is parsed once in `internal/goflags`, which is
+shared by command entry points and the `flags.txt` golden-test driver.
+LLGo-specific command flags such as `-pclntab` remain in
+`cmd/internal/flags`. Both paths write only typed `internal/build.Config`
+fields; the build package does not parse command strings.
+
+The golden-test `flags.txt` format accepts native Go build flags. It accepts
+`-flag=value` and `-flag value`, single or double dashes, blank lines, comments,
+shell-style quoting, and multiple ordinary flags on one line. An unquoted
+argument-list form such as `-ldflags=-s -w=false` consumes the remainder of its
+line; quote that value to put another build flag on the same line. The debug
+fixture uses `-ldflags=-w=false`, so ModeGen debug metadata follows the same
+linker semantics as the CLI.
+
+This is syntax compatibility, not complete linker-backend support. Among
+`-ldflags` options, this change translates only `-s` and `-w` into typed LLGo
+semantics; all other linker tokens remain in the normalized raw flag list and
+do not yet affect LLGo's native link. Only unpatterned and `all=` `-ldflags`
+values are currently interpreted; other package patterns are rejected. The
+existing `-gcflags` frontend subset (`-lang`, `-N`, and `-l`) is separate.
+
+IR golden tests remain non-debug unless a fixture explicitly selects
+`-w=false`, so their `CHECK-NEXT` fixtures continue to describe stable LLVM IR
+and do not depend on the provisional DI implementation. Native integration
+and LLDB suites exercise the explicit-DWARF executable path separately.
+
+`internal/build` validates the selected target, enables compiler metadata,
+coordinates link finalization, and owns output paths. `internal/pclnpost`
+contains host-side ELF/Mach-O inspection and safe binary rewriting.
+`internal/pclnmap` owns the versioned sidecar format. The runtime contains a
+small build-tag-selected loader and an independent, dependency-minimal
+decoder.
+
+This separation keeps both binary-format policy and command syntax out of the
+compiler pipeline.
+
+## Link and strip order
+
+Externalization needs final linked PCs and the native symbol table to remove
+LTO inline copies. It therefore cannot be implemented only by suppressing IR
+generation. The required final-artifact order is:
+
+1. Generate funcinfo and line records, but keep the external payload out of
+   the synthetic main module.
+2. Link the final executable with temporary link-site sections and a fixed
+   identity slot.
+3. Analyze the unmodified executable, join final PCs to the encoded records,
+   and stage the sidecar.
+4. Write the executable identity and clear link-only site data.
+5. Apply any future native symbol-table removal requested by `-s`.
+6. Perform final platform signing after all executable mutations.
+7. Atomically publish the sidecar, then report the executable and sidecar as
+   separate outputs.
+
+#2113 currently implements typed `-s`/`-w` intent and DWARF omission; native
+symbol-table removal is a later phase. When that phase is added, it must use
+the ordering above rather than adding an independent post-link rewrite before
+PCLN analysis. The current external detach step signs a mutated Mach-O itself;
+that signing responsibility must move to the end of the unified pipeline when
+a later native-strip mutation is added.
+
+`-pclntab=none` takes the generation-time path: compiler metadata and link
+sites are not produced. `-pclntab=embedded` keeps the existing post-link
+prebuilt-table rewrite.
+
+Darwin embedded builds that emit DWARF keep the historical site-free path so
+inline PC anchors do not disturb LLDB lexical scopes. Linux retains sites with
+DWARF because most Go symbols are intentionally absent from ELF `.dynsym`, so
+`dlsym` alone cannot reconstruct every function entry. External mode needs
+the final-PC sites on both platforms before it can construct the sidecar.
+
+## Sidecar identity and addressing
+
+The sidecar header contains a format version, runtime ABI version, target
+tuple, pointer size, section descriptors, payload checksum, and the SHA-256
+identity of the exact linked executable before detachment. The same identity
+is written into a dedicated 32-byte executable section. A sidecar is accepted
+only when both values match. It is a pre-mutation pairing token, not the digest
+of the final detached, stripped, or signed executable.
+
+All code addresses are stored relative to the lowest file-backed load segment.
+At runtime they are relocated with the image base returned by `dladdr`, so the
+format works for PIE/ASLR and non-PIE executables without relocations in the
+sidecar.
+
+## Loading and failure semantics
+
+Only allocation and I/O-safe public symbolization paths may start a load.
+Fatal signal handling never loads or waits; it immediately uses the available
+fallback while a load is absent or in progress.
+
+The loader has four states: unattempted, loading, loaded, and unavailable.
+One caller performs validation and index construction. Concurrent callers
+wait only on safe paths. Both success and failure are terminal and cached, so
+the filesystem is never probed repeatedly.
+
+The initial implementation uses one bounded read, capped at 512 MiB, instead
+of `mmap`; read-only mapping remains a possible follow-up optimization.
+
+The format is intentionally private to LLGo and versioned. Its unit is a
+physical function: compiler-generated wrappers and adapters use ordinary
+function records, while calling conventions and closure environment transport
+remain outside PCLN.

+# Stage 5 notes: the FP unwinder's non-obvious invariants
+
+Durable conclusions from bringing up the frame-pointer unwinder (PR #2019).
+Read together with #2019's PR body and `pclntab-linkphase.md`. The full
+session-by-session investigation log lives in the PR discussion.
+
+## Invariants that must not silently degrade
+
+- **pc-1 attribution and the walk bound must survive without the prebuilt
+  table.** When a layout overflows the entry section, the link-phase rewrite
+  backs off and `runtimePrebuiltFtab` stays empty. If `prebuiltTextContains`
+  then answers false, two things turn off silently: the pc-1 return-address
+  convention (frames get attributed to the *next* statement — a return
+  address equals the following pcline anchor exactly) and the FP walk's
+  text bound (libc tail frames decode as wild pcs). The fix is the
+  first-use frame-table fallback bounds in `prebuiltTextContains`, and
+  `fpCallers` building that table up front. Any future change to the table
+  adoption path must keep this fallback alive.
+
+- **Mid-function aligned pcs need pcline merging on amd64.** arm64
+  instructions are 4-byte aligned, so a `ret-1` query is always unaligned
+  and can't collide with a function entry or an aligned-branch lookup.
+  amd64 entries and return addresses are byte-dense: `ret-1` can be
+  4-aligned and can even equal another symbol's entry. Every path that
+  resolves a function record must therefore also consult same-function
+  pcline statement records — this is centralized in `refinePCSymbolLine`
+  (symtab.go); do not add a new resolution path that bypasses it.
+
+- **The two FP walkers must stay in sync.** `fpCallers`
+  (runtime/internal/lib/runtime/unwind_llgo.go) and `llgo_stacktrace`
+  (runtime/internal/clite/debug/_wrap/debug.c) implement the same chain
+  discipline ([fp]/[fp+wordsize], strictly increasing, bounded stride,
+  word alignment). The C walker serves pre-table paths (unrecovered-panic
+  dump, last-resort fallback).
+
+- **The FP attribute is target-gated.** `ssa.Program.NeedsFramePointer()`
+  says where the chain is emitted (linux/darwin, non-embedded, non-wasm);
+  the compiler records the decision in the per-binary `__llgo_fp_chain`
+  byte, and the runtime's `fpUnwindAvailable` trusts that flag plus table
+  presence. On ESP32-C3 the attribute interacted badly with the
+  conservative GC ("clearing nested struct did not free all objects"), so
+  keep embedded targets off unless that is understood.
+
+## Diagnostic traps
+
+- `nm` on `libexport.a` is useless: the archive nests `pkg-*.a` members.
+  Inspect the linked dylib/executable instead.
+- Statement labels can land exactly on return addresses; a "wrong line"
+  report one statement late is the signature of a raw-pc (not pc-1) lookup.
+- An amd64-only symbolization bug with green arm64 almost always traces to
+  one of: byte-dense entries (collisions), 4-aligned ret-1 (aligned-branch
+  path), or the empty-prebuilt fallback above.
+
+## Local repro environments
+
+- colima-qemu / container `llgo-amd64`: amd64 toolchain, stage5 clone at
+  `/root/s5` (rebuild: fetch + reset + `go build -o /usr/local/bin/llgo
+  ./cmd/llgo`).
+- colima-llgo-perf / container `llgo-linux-final`: linux-arm64 bench matrix
+  (mounts /work-s5, /work-2016, /work-2012).
+
+## Merge queue
+
+1. Merge order #2012 -> #2016 -> #2019, rebasing between each.
+2. Semantics PRs 1918/1882/1892/1906 rebase after the merges (1918/1882
+   overlap needs an ordering decision), then reimplement 1925/1903/
+   1924-residual/1905, then P4 (zero-copy names, prebuilt pcline,
+   !pcsections, section shrink) per #2004.

+# Size Report Options
+
+The `llgo build -size` flag emits a TinyGo-style table showing how much code,
+rodata, data, and BSS each component contributes to the final binary. This
+document captures the parsing strategy and new aggregation controls.
+
+## Parsing Strategy
+
+- We invoke `llvm-readelf --elf-output-style=LLVM --all <binary>` and parse the textual output with an
+  indentation-sensitive state machine (no JSON). Only the `Sections` and
+  `Symbols` blocks are inspected.
+- Section metadata records the index, address, size, name, and segment. Each
+  section is classified into text/rodata/data/bss buckets.
+- Symbols are attached to their containing sections with start addresses. By
+  sorting symbols and walking their ranges, we compute byte spans that can be
+  attributed to packages/modules.
+- Sections with no symbols fall back to `(unknown <section>)`, and gaps become
+  `(padding <section>)` entries so totals still add up.
+
+## Aggregation Levels
+
+`-size-level` controls how symbol names are grouped prior to reporting:
+
+| Level     | Behavior                                                                 |
+|-----------|---------------------------------------------------------------------------|
+| `full`    | Keeps the raw owner from the symbol name (previous behavior).             |
+| `package` | Uses the list of packages built in `build.Do` and groups by `pkg.PkgPath`. |
+| `module`* | Default. Groups by `pkg.Module.Path` (or `pkg.PkgPath` if the module is nil). |
+
+Matching is performed by checking whether the demangled symbol name begins with
+`pkg.PkgPath + "."`. Unmatched entries keep the owner derived from their symbol
+name so compiler-generated functions remain visible as ordinary functions
+rather than being grouped by an implementation-specific category.
+
+Defaults:
+
+- `-size` alone enables the report with `-size-format=text` and `-size-level=module`.
+- `-size-format` accepts `text` (table output) or `json`; omitting the flag uses `text`.
+- `-size-level` defaults to `module`, with `package` and `full` as the other options.
+
+Examples:
+
+```sh
+llgo build -size .                     # module-level aggregation (default)
+llgo build -size -size-level=package . # collapse by package ID
+llgo build -size -size-level=full .    # show raw symbol owners
+llgo build -size -size-format=json .   # JSON output (works with all levels)
+```
+
+## Validation
+
+1. Unit tests: `go test ./internal/build -run TestParseReadelfOutput -count=1`.
+2. Real binary test:
+   ```sh
+   cd cl/_testgo/rewrite
+   ../../../dev/llgo.sh build .
+   LLGO_SIZE_REPORT_BIN=$(pwd)/rewrite \
+     go test ./internal/build -run TestParseReadelfRealBinary -count=1
+   ```
+3. Manual smoke test: `../../../dev/llgo.sh build -size -size-level=module .` (or
+   `package`/`full` as desired).
+
+The parser works across Mach-O and ELF targets as long as `llvm-readelf` is in
+`PATH`.

+Proposal draft (prepared from the analysis docs in llgo-closure-ctxreg-docs-20260122, updated 2026-01-22).
+
+# Proposal: LLGo Syscall Intrinsics for Full Go Stdlib Reuse
+
+## Goals
+
+- Reuse Go standard library syscall wrappers without assembly trampolines.
+- Provide a small, explicit set of LLGo intrinsics to cover **all** supported OSes.
+- Clarify how to handle scheduler hooks (`entersyscall`/`exitsyscall`) without
+  generating code at call sites.
+
+## Non-Goals
+
+- Rewriting Go's runtime or syscall package code.
+- Supporting JS/WASM syscall (uses `syscall/js` runtime layer, not traditional syscalls).
+
+## Background
+
+Go uses multiple syscall mechanisms depending on platform:
+
+- **Darwin/OpenBSD/iOS**: libc trampolines (`abi.FuncPCABI0(libc_xxx_trampoline)`).
+- **Linux/FreeBSD/NetBSD/DragonFly/Android**: raw syscall numbers (`Syscall(SYS_XXX, ...)`).
+- **Windows**: DLL proc calls (`LazyDLL`/`LazyProc` + `SyscallN`).
+- **Solaris/illumos**: sysvicall6 with libc pointer indirection.
+- **AIX**: syscall6 with libc pointer indirection.
+- **WASI**: `//go:wasmimport`.
+- **Plan 9**: raw syscall numbers with `ErrorString` return type.
+- **JS (GOOS=js/wasm)**: no traditional syscall (uses `syscall/js` and runtime shims).
+
+## Proposed Intrinsics
+
+### 1. `llgo.funcPCABI0`
+
+**Purpose:** Convert trampoline functions into C symbol addresses.
+
+- Detect `*_trampoline` symbols with empty bodies.
+- Apply name extraction rules:
+  - `libc_XXX_trampoline` -> `XXX`
+  - `XXX_trampoline` -> `XXX`
+- Return the external symbol address as `uintptr`.
+
+### 2. Syscall Intrinsics by Platform Category
+
+#### Category A: `llgo.syscall` (single intrinsic logic with aliases)
+
+**Purpose:** Implement all libc-trampoline-based syscall wrappers (`syscall`,
+`syscall6`, `syscall6X`, `syscallPtr`, `rawSyscall`, `rawSyscall6`). Uses
+function pointer from `abi.FuncPCABI0`.
+
+```go
+//go:linkname syscall llgo.syscall
+func syscall(fn, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+
+//go:linkname syscall6 llgo.syscall
+func syscall6(fn, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+
+//go:linkname syscall6X llgo.syscall
+func syscall6X(fn, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+
+//go:linkname syscallPtr llgo.syscall
+func syscallPtr(fn, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+
+//go:linkname rawSyscall llgo.syscall
+func rawSyscall(fn, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+
+//go:linkname rawSyscall6 llgo.syscall
+func rawSyscall6(fn, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+```
+
+**Compiler policy:** All of the above linknames are treated as a **single
+intrinsic** in the compiler (same lowering logic). This avoids Go-variadic
+lowering into slices while still keeping the standard library signatures.
+
+Behavior:
+
+- Cast `fn` to function pointer and call directly with N arguments.
+- Check result == -1 and fetch errno via `__error()` (Darwin/FreeBSD) or `__errno()` (OpenBSD).
+- Return `(r1, r2, err)` as required by Go's `syscall` package.
+
+#### Category B: `llgo.Syscall` (Linux, FreeBSD, NetBSD, DragonFly)
+
+**Purpose:** Support syscall-number-based calls. Maps syscall numbers to libc functions.
+
+```go
+//go:linkname Syscall llgo.Syscall
+func Syscall(trap, a1, a2, a3 uintptr) (r1, r2 uintptr, err Errno)
+
+//go:linkname Syscall6 llgo.Syscall6
+func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2 uintptr, err Errno)
+
+//go:linkname RawSyscall llgo.RawSyscall
+func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2 uintptr, err Errno)
+
+//go:linkname RawSyscall6 llgo.RawSyscall6
+func RawSyscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2 uintptr, err Errno)
+```
+
+Implementation options:
+
+1. **Map to libc** (recommended): Look up libc function by syscall number
+2. **Inline syscall**: Generate platform-specific syscall instruction
+
+Android note: Bionic/SECCOMP can block raw syscalls, so libc mapping is safer.
+
+#### Category C: `llgo.sysvicall6` (Solaris, Illumos)
+
+**Purpose:** Support SYSV-style libc calls with pointer indirection.
+
+```go
+//go:linkname sysvicall6 llgo.sysvicall6
+func sysvicall6(trap, nargs, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+
+//go:linkname rawSysvicall6 llgo.rawSysvicall6
+func rawSysvicall6(trap, nargs, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+```
+
+The first argument is a pointer to `libcFunc` variable. LLGo should:
+
+1. Dereference to get function pointer
+2. Call with the given arguments
+3. Fetch errno via `___errno()`
+
+#### Category D: AIX (wrapper around `llgo.syscall`)
+
+**Purpose:** AIX uses libc function pointers plus an explicit `nargs` parameter.
+We can implement the standard wrapper in Go and call `llgo.syscall` with the
+appropriate number of arguments. No new intrinsic is required.
+
+Pattern in `zsyscall_aix_ppc64.go`:
+
+```go
+_, _, e1 := syscall6(uintptr(unsafe.Pointer(&libc_Dup2)), 2, uintptr(old), uintptr(new), 0, 0, 0, 0)
+```
+
+`syscall6` should be a Go wrapper that forwards the first `nargs` arguments to
+`llgo.syscall` and fetches errno via `_Errno()`.
+
+#### Category E: `llgo.SyscallWindows` (Windows)
+
+**Purpose:** Support Windows DLL procedure calls.
+
+```go
+//go:linkname Syscall llgo.SyscallWindows
+func Syscall(trap, nargs, a1, a2, a3 uintptr) (r1, r2 uintptr, err Errno)
+
+//go:linkname Syscall6 llgo.Syscall6Windows
+func Syscall6(trap, nargs, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2 uintptr, err Errno)
+
+//go:linkname Syscall9 llgo.Syscall9Windows
+func Syscall9(trap, nargs, a1, a2, a3, a4, a5, a6, a7, a8, a9 uintptr) (r1, r2 uintptr, err Errno)
+
+// ... Syscall12, Syscall15, Syscall18
+
+//go:linkname SyscallN llgo.SyscallNWindows
+func SyscallN(trap uintptr, args ...uintptr) (r1, r2 uintptr, err Errno)
+```
+
+Additional runtime support needed:
+
+- `LazyDLL.Load()` → calls `LoadLibraryW`
+- `LazyProc.Find()` → calls `GetProcAddress`
+- Error handling via `GetLastError()`
+
+#### Category F: `llgo.SyscallPlan9` (Plan 9)
+
+**Purpose:** Support Plan 9 syscalls with `ErrorString` return type.
+
+```go
+//go:linkname Syscall llgo.SyscallPlan9
+func Syscall(trap, a1, a2, a3 uintptr) (r1, r2 uintptr, err ErrorString)
+
+//go:linkname Syscall6 llgo.Syscall6Plan9
+func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2 uintptr, err ErrorString)
+```
+
+**Key insight:** Plan 9 is **fully reusable** because `ErrorString` implements `error`:
+
+```go
+type ErrorString string
+func (e ErrorString) Error() string { return string(e) }
+
+// In zsyscall_plan9_*.go:
+func open(path string, mode int) (fd int, err error) {
+    r0, _, e1 := Syscall(SYS_OPEN, ...)  // e1 is ErrorString
+    if int32(r0) == -1 {
+        err = e1  // ErrorString implements error interface
+    }
+    return
+}
+```
+
+Error handling: Call `errstr()` on failure to get error string.
+
+#### Category G: WASI
+
+```go
+//go:wasmimport wasi_snapshot_preview1 fd_read
+func fd_read(fd int32, iovs *iovec, iovsLen size, nread *size) Errno
+```
+
+**Compiler support:** Generate WASM import declarations directly. No syscall intrinsics required.
+
+### 3. `llgo.skip` (No-op Call Marker)
+
+**Purpose:** Remove calls while preserving types.
+
+Usage example:
+
+```go
+//go:linkname entersyscall llgo.skip
+//go:linkname exitsyscall llgo.skip
+func entersyscall()
+func exitsyscall()
+```
+
+Behavior:
+
+- Any call to `llgo.skip` emits no code at call site.
+- Symbol declaration is also suppressed.

+## Errno Retrieval Functions by Platform
+
+| Platform           | Function             | Notes                       |
+| ------------------ | -------------------- | --------------------------- |
+| Darwin (macOS/iOS) | `__error()`          | Returns `*int`              |
+| FreeBSD            | `__error()`          | Same as Darwin              |

+| Plan 9             | `errstr()`           | Returns error string        |
+
+---
+
+## Runtime Trampolines Analysis
+
+The `runtime` package on Darwin/OpenBSD uses its own set of trampolines (separate from syscall package). These are **not blockers** for syscall package reuse since LLGo has its own runtime:
+
+| Category   | Trampolines                                                             |
+| ---------- | ----------------------------------------------------------------------- |
+| I/O        | `write`, `read`, `open`, `close`                                        |
+| Memory     | `mmap`, `munmap`, `madvise`                                             |
+| Threading  | `pthread_create`, `pthread_mutex_*`, `pthread_cond_*`, `pthread_attr_*` |
+| Time/Sleep | `nanotime`, `usleep`                                                    |
+| Signals    | `raise`, `pthread_kill`, `sigaction`, `sigprocmask`                     |
+| Events     | `kevent`, `kqueue`                                                      |
+
+For LLGo's runtime, implement these as direct C calls:
+
+```go
+// In LLGo runtime (runtime/c package)
+//go:linkname write C.write
+func write(fd int32, p unsafe.Pointer, n int32) int32
+```

+
+## Implementation Plan
+
+### Phase 1: Darwin/OpenBSD (Proof of Concept)
+
+1. Implement `llgo.funcPCABI0` intrinsic
+2. Implement `llgo.syscall` family intrinsics (lowercase)
+3. Use `llgo.skip` for `entersyscall`/`exitsyscall`
+4. Skip all `.s` files in syscall package
+5. Test with `zsyscall_darwin_arm64.go`
+
+### Phase 2: Linux
+
+1. Create syscall number → libc function mapping
+2. Implement `llgo.Syscall` (capital S) for numeric syscalls
+3. Test with `zsyscall_linux_amd64.go`
+
+### Phase 3: Other Unix-like
+
+1. FreeBSD, NetBSD, DragonFly - reuse Linux intrinsics with platform-specific errno
+2. Solaris - implement `llgo.sysvicall6`
+3. AIX - implement Go wrapper around `llgo.syscall`
+
+### Phase 4: Windows
+
+1. Implement `LazyDLL`/`LazyProc` in LLGo runtime
+2. Implement `Syscall`/`Syscall6`/.../`SyscallN`
+3. Test with `zsyscall_windows.go`
+
+### Phase 5: Special Platforms
+
+1. WASI - Support `//go:wasmimport` directive
+2. Plan 9 - Implement `llgo.SyscallPlan9` with ErrorString return
+3. JS/WASM - Implement `syscall/js` package (no syscall reuse)
+
+---
+
+## Open Questions
+
+- Should we standardize on fixed arity (3/6/9) or use variadic `llgo.syscallN`?
+- How much syscall number → libc mapping should be auto-generated from Go's `zsysnum_*` files vs. a maintained table?
+- Do we need to preserve scheduler hooks for certain LLGo configurations?
+
+---
+
+## Appendix A: Platform Mechanisms and LLGo Implications
+
+| Platform                     | Mechanism           | Key Go Sources (examples)       | LLGo Implication                       |
+| ---------------------------- | ------------------- | ------------------------------- | -------------------------------------- |
+| Darwin / iOS                 | libc trampoline     | `syscall/zsyscall_darwin_*.go`  | `llgo.funcPCABI0` + `llgo.syscall`     |
+| OpenBSD                      | libc trampoline     | `syscall/zsyscall_openbsd_*.go` | Same as Darwin                         |
+| Linux                        | raw syscall numbers | `syscall/zsyscall_linux_*.go`   | Map syscall numbers → libc             |
+| Android                      | raw syscall numbers | `syscall/syscall_linux.go`      | Same as Linux, prefer libc for SECCOMP |
+| FreeBSD / NetBSD / DragonFly | raw syscall numbers | `syscall/zsyscall_*bsd_*.go`    | Same as Linux strategy                 |
+| Solaris / illumos            | sysvicall → libc    | `syscall/zsyscall_solaris_*.go` | `llgo.sysvicall6`                      |
+| AIX                          | syscall6 via libc   | `syscall/zsyscall_aix_*.go`     | `llgo.syscall` (wrapper)               |
+| Windows                      | DLL proc calls      | `syscall/zsyscall_windows.go`   | `llgo.SyscallWindows` + LazyDLL        |
+| WASI                         | wasm imports        | `syscall/fs_wasip1.go`          | `//go:wasmimport`                      |

+| Plan 9                       | syscall + errstr    | `syscall/zsyscall_plan9_*.go`   | `llgo.SyscallPlan9` with ErrorString   |
+
+## Appendix B: Trampoline Name Extraction Rules
+
+Extraction is based on `*_trampoline` suffix:
+
+```
+libc_XXX_trampoline  -> XXX
+XXX_trampoline       -> XXX
+```
+
+Suggested detection algorithm:
+
+```go
+func extractCFunctionName(trampoline string) string {
+    if !strings.HasSuffix(trampoline, "_trampoline") {
+        return ""
+    }
+    base := strings.TrimSuffix(trampoline, "_trampoline")
+    if strings.HasPrefix(base, "libc_") {
+        return strings.TrimPrefix(base, "libc_")
+    }
+    return base
+}
+```
+
+## Appendix C: Darwin/OpenBSD Call Chain (Why Intrinsics Work)
+
+Go's syscall path on Darwin/OpenBSD includes multiple layers:
+
+1. `syscall` wrappers call `syscall(abi.FuncPCABI0(libc_xxx_trampoline), ...)`
+2. Runtime wrapper `syscall_syscall` builds an args struct
+3. `libcCall` + `asmcgocall` switch to system stack
+4. `runtime.syscall` trampoline unpacks args and calls libc
+
+LLGo can bypass layers 2-4 by:
+
+- Recognizing `abi.FuncPCABI0(libc_xxx_trampoline)` and returning `@xxx`
+- Lowering `syscall()` directly to a libc call with errno handling
+
+## Appendix D: Example Snippets
+
+### D1. Darwin/OpenBSD Wrapper Pattern
+
+```go
+func Lchown(path string, uid int, gid int) (err error) {
+    var _p0 *byte
+    _p0, err = BytePtrFromString(path)
+    if err != nil {
+        return
+    }
+    _, _, e1 := syscall(abi.FuncPCABI0(libc_lchown_trampoline),
+                        uintptr(unsafe.Pointer(_p0)), uintptr(uid), uintptr(gid))
+    if e1 != 0 {
+        err = errnoErr(e1)
+    }
+    return
+}
+
+func libc_lchown_trampoline()
+```
+
+### D2. Direct Call Lowering (illustrative)
+
+```llvm
+; abi.FuncPCABI0(libc_lchown_trampoline) -> @lchown
+%result = call i32 @lchown(ptr %cstr, i32 %uid, i32 %gid)
+%is_err = icmp eq i32 %result, -1
+br i1 %is_err, label %get_errno, label %done
+```
+
+### D3. Windows LazyDLL / Proc Pattern
+
+```go
+var modkernel32 = NewLazyDLL("kernel32.dll")
+var procReadFile = modkernel32.NewProc("ReadFile")
+
+func ReadFile(handle Handle, buf []byte, done *uint32, ov *Overlapped) (err error) {
+    r1, _, e1 := Syscall6(procReadFile.Addr(), 5,
+        uintptr(handle), uintptr(unsafe.Pointer(&buf[0])), uintptr(len(buf)),
+        uintptr(unsafe.Pointer(done)), uintptr(unsafe.Pointer(ov)), 0)
+    if r1 == 0 {
+        err = errnoErr(e1)
+    }
+    return
+}
+```
+
+### D4. WASI Import Pattern
+
+```go
+//go:wasmimport wasi_snapshot_preview1 fd_read
+//go:noescape
+func fd_read(fd int32, iovs *iovec, iovsLen size, nread *size) Errno
+```
+
+### D5. Plan 9 Pattern (Fully Reusable)
+
+```go
+// ErrorString implements error interface
+type ErrorString string
+func (e ErrorString) Error() string { return string(e) }
+
+func open(path string, mode int) (fd int, err error) {
+    r0, _, e1 := Syscall(SYS_OPEN, uintptr(unsafe.Pointer(_p0)), uintptr(mode), 0)
+    fd = int(r0)
+    if int32(r0) == -1 {
+        err = e1  // e1 is ErrorString, implements error
+    }
+    return
+}
+```
+
+### D6. No-op Call Marker
+
+```go
+//go:linkname entersyscall llgo.skip
+//go:linkname exitsyscall llgo.skip
+func entersyscall()
+func exitsyscall()
+```

+// fixSSAOrder applies small SSA fixups for stdlib compatibility.
+//
+// go/ssa follows the spec's operand evaluation rules (only calls/receives/logical
+// ops are ordered). Some stdlib code relies on the Go compiler's de-facto choice
+// of delaying non-call operands, e.g. patterns like:
+//
+//	var o T
+//	return o, o.mutate()
+//
+// where mutate has a pointer receiver and sets fields in o. go/ssa may materialize
+// the first return value as a load before the call, which makes o appear unchanged
+// to the return value in our backend.
+//
+// This pass moves loads of local allocs that feed a Return result and have no
+// intervening executable use before that Return to after any intervening calls
+// that use the same alloc pointer, matching the behavior of the Go compiler for
+// the stdlib cases we rely on (e.g. crypto/x509.ParseOID).

+# gohex
+A Go library for parsing Intel HEX files
+
+## Documentation:
+https://godoc.org/github.com/marcinbor85/gohex
+
+## Features:
+* robust intelhex parsing (full test coverage)
+* support i32hex format
+* two-way converting hex<->bin
+* trivial but powerful api (only the most commonly used functions)
+* interface-based IO functions
+
+## Examples:
+
+### Loading IntelHex file:
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/marcinbor85/gohex"
+	"os"
+)
+
+func main() {
+	file, err := os.Open("example.hex")
+	if err != nil {
+		panic(err)
+	}
+	defer file.Close()
+	
+	mem := gohex.NewMemory()
+	err = mem.ParseIntelHex(file)
+	if err != nil {
+		panic(err)
+	}
+	for _, segment := range mem.GetDataSegments() {
+		fmt.Printf("%+v\n", segment)
+	}
+	bytes := mem.ToBinary(0xFFF0, 128, 0x00)
+	fmt.Printf("%v\n", bytes)
+}
+```
+
+### Dumping IntelHex file:
+```go
+package main
+
+import (
+	"github.com/marcinbor85/gohex"
+	"os"
+)
+
+func main() {
+	file, err := os.Create("output.hex")
+	if err != nil {
+		panic(err)
+	}
+	defer file.Close()
+	
+	mem := gohex.NewMemory()
+	mem.SetStartAddress(0x80008000)
+	mem.AddBinary(0x10008000, []byte{0x01,0x02,0x03,0x04})
+	mem.AddBinary(0x20000000, make([]byte, 256))
+	
+	mem.DumpIntelHex(file, 16)
+}
+```

+# LLGo LTO Plugin
+
+This directory contains the optional LLVM new pass manager plugin used by LLGo
+full LTO builds. It is not required to build or use LLGo.
+
+Build with the same LLVM 19 toolchain used by LLGo:
+
+```sh
+cmake -S ltoplugin -B ltoplugin/build \
+  -DLLVM_DIR=/path/to/llvm-19/lib/cmake/llvm \
+  -DCMAKE_BUILD_TYPE=Release
+cmake --build ltoplugin/build
+```
+
+Load the plugin when building with full LTO on Linux/ELF:
+
+```sh
+llgo build -lto=full -lto-pass-plugin=/path/to/LLGOLTOPlugin.so ./...
+```
+
+On macOS, the built plugin usually uses the `.dylib` suffix.
+
+The plugin registers `llgo-lto-pre-globaldce` and also inserts that pass through
+LLVM's full LTO early extension point, so loading the plugin is enough for the
+pass to run before the normal full LTO optimization pipeline proceeds.
+
+LLGo forwards the plugin path through lld's `--load-pass-plugin` option. LLVM 19
+`ld64.lld` and Apple `ld64` do not expose an equivalent new pass manager LTO
+plugin loading option for Mach-O links, so LLGo rejects `-lto-pass-plugin` for
+Darwin targets until the linker side grows that support.

+
+      "Derivative Works" shall mean any work, whether in Source or Object

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

-	//
-	// Interpreting the heap statistics requires some knowledge of

-	// regions of memory 8K or larger. A span may be in one of

-	//
-	// An "idle" span contains no objects or other data. The

-	// can be converted into an "in use" or "stack" span.
-	//
-	// An "in use" span contains at least one heap object and may
-	// have free space available to allocate more heap objects.
-	//
-	// A "stack" span is used for goroutine stacks. Stack spans
-	// are not considered part of the heap. A span can change
-	// between heap and stack memory; it is never used for both

-
-	// HeapAlloc is bytes of allocated heap objects.
-	//
-	// "Allocated" heap objects include all reachable objects, as
-	// well as unreachable objects that the garbage collector has
-	// not yet freed. Specifically, HeapAlloc increases as heap
-	// objects are allocated and decreases as the heap is swept
-	// and unreachable objects are freed. Sweeping occurs
-	// incrementally between GC cycles, so these two processes
-	// occur simultaneously, and as a result HeapAlloc tends to
-	// change smoothly (in contrast with the sawtooth that is
-	// typical of stop-the-world garbage collectors).
-	HeapAlloc uint64
-
-	// HeapSys is bytes of heap memory obtained from the OS.

-	// HeapIdle minus HeapReleased estimates the amount of memory
-	// that could be returned to the OS, but is being retained by

-	HeapInuse uint64

-// Package testing provides support for automated testing of Go packages.
-// It is intended to be used in concert with the "go test" command, which automates
-// execution of any function of the form
-//
-//	func TestXxx(*testing.T)
-//
-// where Xxx does not start with a lowercase letter. The function name
-// serves to identify the test routine.
-//
-// Within these functions, use the Error, Fail or related methods to signal failure.
-//
-// To write a new test suite, create a file that
-// contains the TestXxx functions as described here,
-// and give that file a name ending in "_test.go".
-// The file will be excluded from regular
-// package builds but will be included when the "go test" command is run.
-//
-// The test file can be in the same package as the one being tested,
-// or in a corresponding package with the suffix "_test".
-//
-// If the test file is in the same package, it may refer to unexported
-// identifiers within the package, as in this example:
-//
-//	package abs
-//
-//	import "testing"
-//
-//	func TestAbs(t *testing.T) {
-//	    got := Abs(-1)
-//	    if got != 1 {
-//	        t.Errorf("Abs(-1) = %d; want 1", got)
-//	    }
-//	}
-//
-// If the file is in a separate "_test" package, the package being tested
-// must be imported explicitly and only its exported identifiers may be used.
-// This is known as "black box" testing.
-//
-//	package abs_test
-//
-//	import (
-//		"testing"
-//
-//		"path_to_pkg/abs"
-//	)
-//
-//	func TestAbs(t *testing.T) {

-//	    if got != 1 {
-//	        t.Errorf("Abs(-1) = %d; want 1", got)
-//	    }
-//	}
-//

-//
-// # Benchmarks
-//
-// Functions of the form
-//
-//	func BenchmarkXxx(*testing.B)
-//
-// are considered benchmarks, and are executed by the "go test" command when
-// its -bench flag is provided. Benchmarks are run sequentially.
-//
-// For a description of the testing flags, see
-// https://golang.org/cmd/go/#hdr-Testing_flags.
-//
-// A sample benchmark function looks like this:
-//
-//	func BenchmarkRandInt(b *testing.B) {
-//	    for range b.N {
-//	        rand.Int()
-//	    }
-//	}
-//
-// The benchmark function must run the target code b.N times.
-// It is called multiple times with b.N adjusted until the
-// benchmark function lasts long enough to be timed reliably.
-// The output
-//
-//	BenchmarkRandInt-8   	68453040	        17.8 ns/op
-//
-// means that the loop ran 68453040 times at a speed of 17.8 ns per loop.
-//
-// If a benchmark needs some expensive setup before running, the timer
-// may be reset:
-//
-//	func BenchmarkBigLen(b *testing.B) {
-//	    big := NewBig()
-//	    b.ResetTimer()
-//	    for range b.N {
-//	        big.Len()
-//	    }
-//	}
-//
-// If a benchmark needs to test performance in a parallel setting, it may use
-// the RunParallel helper function; such benchmarks are intended to be used with
-// the go test -cpu flag:
-//
-//	func BenchmarkTemplateParallel(b *testing.B) {
-//	    templ := template.Must(template.New("test").Parse("Hello, {{.}}!"))
-//	    b.RunParallel(func(pb *testing.PB) {
-//	        var buf bytes.Buffer
-//	        for pb.Next() {
-//	            buf.Reset()
-//	            templ.Execute(&buf, "World")
-//	        }
-//	    })
-//	}
-//
-// A detailed specification of the benchmark results format is given
-// in https://golang.org/design/14313-benchmark-format.
-//
-// There are standard tools for working with benchmark results at
-// https://golang.org/x/perf/cmd.
-// In particular, https://golang.org/x/perf/cmd/benchstat performs
-// statistically robust A/B comparisons.
-//
-// # Examples
-//
-// The package also runs and verifies example code. Example functions may
-// include a concluding line comment that begins with "Output:" and is compared with
-// the standard output of the function when the tests are run. (The comparison
-// ignores leading and trailing space.) These are examples of an example:
-//
-//	func ExampleHello() {
-//	    fmt.Println("hello")
-//	    // Output: hello
-//	}
-//
-//	func ExampleSalutations() {
-//	    fmt.Println("hello, and")
-//	    fmt.Println("goodbye")
-//	    // Output:
-//	    // hello, and
-//	    // goodbye
-//	}
-//
-// The comment prefix "Unordered output:" is like "Output:", but matches any
-// line order:
-//
-//	func ExamplePerm() {
-//	    for _, value := range Perm(5) {
-//	        fmt.Println(value)
-//	    }
-//	    // Unordered output: 4
-//	    // 2
-//	    // 1
-//	    // 3
-//	    // 0
-//	}
-//
-// Example functions without output comments are compiled but not executed.
-//
-// The naming convention to declare examples for the package, a function F, a type T and
-// method M on type T are:
-//
-//	func Example() { ... }
-//	func ExampleF() { ... }
-//	func ExampleT() { ... }
-//	func ExampleT_M() { ... }
-//
-// Multiple example functions for a package/type/function/method may be provided by
-// appending a distinct suffix to the name. The suffix must start with a
-// lower-case letter.
-//
-//	func Example_suffix() { ... }
-//	func ExampleF_suffix() { ... }
-//	func ExampleT_suffix() { ... }
-//	func ExampleT_M_suffix() { ... }
-//
-// The entire test file is presented as the example when it contains a single
-// example function, at least one other function, type, variable, or constant
-// declaration, and no test or benchmark functions.
-//
-// # Fuzzing
-//
-// 'go test' and the testing package support fuzzing, a testing technique where
-// a function is called with randomly generated inputs to find bugs not
-// anticipated by unit tests.
-//
-// Functions of the form
-//
-//	func FuzzXxx(*testing.F)
-//
-// are considered fuzz tests.
-//
-// For example:
-//
-//	func FuzzHex(f *testing.F) {
-//	  for _, seed := range [][]byte{{}, {0}, {9}, {0xa}, {0xf}, {1, 2, 3, 4}} {
-//	    f.Add(seed)
-//	  }
-//	  f.Fuzz(func(t *testing.T, in []byte) {
-//	    enc := hex.EncodeToString(in)
-//	    out, err := hex.DecodeString(enc)
-//	    if err != nil {
-//	      t.Fatalf("%v: decode: %v", in, err)
-//	    }
-//	    if !bytes.Equal(in, out) {
-//	      t.Fatalf("%v: not equal after round trip: %v", in, out)
-//	    }
-//	  })
-//	}
-//
-// A fuzz test maintains a seed corpus, or a set of inputs which are run by
-// default, and can seed input generation. Seed inputs may be registered by
-// calling (*F).Add or by storing files in the directory testdata/fuzz/<Name>
-// (where <Name> is the name of the fuzz test) within the package containing
-// the fuzz test. Seed inputs are optional, but the fuzzing engine may find
-// bugs more efficiently when provided with a set of small seed inputs with good
-// code coverage. These seed inputs can also serve as regression tests for bugs
-// identified through fuzzing.
-//
-// The function passed to (*F).Fuzz within the fuzz test is considered the fuzz
-// target. A fuzz target must accept a *T parameter, followed by one or more
-// parameters for random inputs. The types of arguments passed to (*F).Add must
-// be identical to the types of these parameters. The fuzz target may signal
-// that it's found a problem the same way tests do: by calling T.Fail (or any
-// method that calls it like T.Error or T.Fatal) or by panicking.
-//
-// When fuzzing is enabled (by setting the -fuzz flag to a regular expression
-// that matches a specific fuzz test), the fuzz target is called with arguments
-// generated by repeatedly making random changes to the seed inputs. On
-// supported platforms, 'go test' compiles the test executable with fuzzing
-// coverage instrumentation. The fuzzing engine uses that instrumentation to
-// find and cache inputs that expand coverage, increasing the likelihood of
-// finding bugs. If the fuzz target fails for a given input, the fuzzing engine
-// writes the inputs that caused the failure to a file in the directory
-// testdata/fuzz/<Name> within the package directory. This file later serves as
-// a seed input. If the file can't be written at that location (for example,
-// because the directory is read-only), the fuzzing engine writes the file to
-// the fuzz cache directory within the build cache instead.
-//
-// When fuzzing is disabled, the fuzz target is called with the seed inputs
-// registered with F.Add and seed inputs from testdata/fuzz/<Name>. In this
-// mode, the fuzz test acts much like a regular test, with subtests started
-// with F.Fuzz instead of T.Run.
-//
-// See https://go.dev/doc/fuzz for documentation about fuzzing.
-//
-// # Skipping
-//
-// Tests or benchmarks may be skipped at run time with a call to
-// the Skip method of *T or *B:
-//
-//	func TestTimeConsuming(t *testing.T) {
-//	    if testing.Short() {
-//	        t.Skip("skipping test in short mode.")
-//	    }
-//	    ...
-//	}
-//
-// The Skip method of *T can be used in a fuzz target if the input is invalid,
-// but should not be considered a failing input. For example:
-//
-//	func FuzzJSONMarshaling(f *testing.F) {
-//	    f.Fuzz(func(t *testing.T, b []byte) {
-//	        var v interface{}
-//	        if err := json.Unmarshal(b, &v); err != nil {
-//	            t.Skip()
-//	        }
-//	        if _, err := json.Marshal(v); err != nil {
-//	            t.Errorf("Marshal: %v", err)
-//	        }
-//	    })
-//	}
-//
-// # Subtests and Sub-benchmarks
-//
-// The Run methods of T and B allow defining subtests and sub-benchmarks,
-// without having to define separate functions for each. This enables uses
-// like table-driven benchmarks and creating hierarchical tests.
-// It also provides a way to share common setup and tear-down code:
-//
-//	func TestFoo(t *testing.T) {
-//	    // <setup code>
-//	    t.Run("A=1", func(t *testing.T) { ... })
-//	    t.Run("A=2", func(t *testing.T) { ... })
-//	    t.Run("B=1", func(t *testing.T) { ... })
-//	    // <tear-down code>
-//	}
-//
-// Each subtest and sub-benchmark has a unique name: the combination of the name
-// of the top-level test and the sequence of names passed to Run, separated by
-// slashes, with an optional trailing sequence number for disambiguation.
-//
-// The argument to the -run, -bench, and -fuzz command-line flags is an unanchored regular
-// expression that matches the test's name. For tests with multiple slash-separated
-// elements, such as subtests, the argument is itself slash-separated, with
-// expressions matching each name element in turn. Because it is unanchored, an
-// empty expression matches any string.
-// For example, using "matching" to mean "whose name contains":
-//
-//	go test -run ''        # Run all tests.
-//	go test -run Foo       # Run top-level tests matching "Foo", such as "TestFooBar".
-//	go test -run Foo/A=    # For top-level tests matching "Foo", run subtests matching "A=".
-//	go test -run /A=1      # For all top-level tests, run subtests matching "A=1".
-//	go test -fuzz FuzzFoo  # Fuzz the target matching "FuzzFoo"
-//
-// The -run argument can also be used to run a specific value in the seed
-// corpus, for debugging. For example:
-//
-//	go test -run=FuzzFoo/9ddb952d9814
-//
-// The -fuzz and -run flags can both be set, in order to fuzz a target but
-// skip the execution of all other tests.
-//
-// Subtests can also be used to control parallelism. A parent test will only
-// complete once all of its subtests complete. In this example, all tests are
-// run in parallel with each other, and only with each other, regardless of
-// other top-level tests that may be defined:
-//
-//	func TestGroupedParallel(t *testing.T) {
-//	    for _, tc := range tests {
-//	        tc := tc // capture range variable
-//	        t.Run(tc.Name, func(t *testing.T) {
-//	            t.Parallel()
-//	            ...
-//	        })
-//	    }
-//	}
-//
-// Run does not return until parallel subtests have completed, providing a way
-// to clean up after a group of parallel tests:
-//
-//	func TestTeardownParallel(t *testing.T) {
-//	    // This Run will not return until the parallel tests finish.
-//	    t.Run("group", func(t *testing.T) {
-//	        t.Run("Test1", parallelTest1)
-//	        t.Run("Test2", parallelTest2)
-//	        t.Run("Test3", parallelTest3)
-//	    })
-//	    // <tear-down code>
-//	}
-//
-// # Main
-//
-// It is sometimes necessary for a test or benchmark program to do extra setup or teardown
-// before or after it executes. It is also sometimes necessary to control
-// which code runs on the main thread. To support these and other cases,
-// if a test file contains a function:
-//
-//	func TestMain(m *testing.M)
-//
-// then the generated test will call TestMain(m) instead of running the tests or benchmarks
-// directly. TestMain runs in the main goroutine and can do whatever setup
-// and teardown is necessary around a call to m.Run. m.Run will return an exit
-// code that may be passed to os.Exit. If TestMain returns, the test wrapper
-// will pass the result of m.Run to os.Exit itself.
-//
-// When TestMain is called, flag.Parse has not been run. If TestMain depends on
-// command-line flags, including those of the testing package, it should call
-// flag.Parse explicitly. Command line flags are always parsed by the time test
-// or benchmark functions run.
-//
-// A simple implementation of TestMain is:
-//
-//	func TestMain(m *testing.M) {
-//		// call flag.Parse() here if TestMain uses flags
-//		m.Run()
-//	}
-//
-// TestMain is a low-level primitive and should not be necessary for casual
-// testing needs, where ordinary test functions suffice.

-//
-// Within these functions, use the Error, Fail or related methods to signal failure.
-//
-// To write a new test suite, create a file that

-//
-// For a description of the testing flags, see
-// https://golang.org/cmd/go/#hdr-Testing_flags.
-//
-// A sample benchmark function looks like this:
-//
-//	func BenchmarkRandInt(b *testing.B) {
-//	    for b.Loop() {
-//	        rand.Int()
-//	    }
-//	}
-//
-// The output
-//
-//	BenchmarkRandInt-8   	68453040	        17.8 ns/op
-//
-// means that the body of the loop ran 68453040 times at a speed of 17.8 ns per loop.
-//
-// Only the body of the loop is timed, so benchmarks may do expensive
-// setup before calling b.Loop, which will not be counted toward the
-// benchmark measurement:
-//
-//	func BenchmarkBigLen(b *testing.B) {
-//	    big := NewBig()
-//	    for b.Loop() {
-//	        big.Len()
-//	    }
-//	}
-//
-// If a benchmark needs to test performance in a parallel setting, it may use
-// the RunParallel helper function; such benchmarks are intended to be used with
-// the go test -cpu flag:
-//
-//	func BenchmarkTemplateParallel(b *testing.B) {
-//	    templ := template.Must(template.New("test").Parse("Hello, {{.}}!"))
-//	    b.RunParallel(func(pb *testing.PB) {
-//	        var buf bytes.Buffer
-//	        for pb.Next() {
-//	            buf.Reset()
-//	            templ.Execute(&buf, "World")
-//	        }
-//	    })
-//	}
-//
-// A detailed specification of the benchmark results format is given
-// in https://golang.org/design/14313-benchmark-format.
-//
-// There are standard tools for working with benchmark results at
-// https://golang.org/x/perf/cmd.
-// In particular, https://golang.org/x/perf/cmd/benchstat performs
-// statistically robust A/B comparisons.

-//
-// Prior to the introduction of [B.Loop], benchmarks were written in a
-// different style using B.N. For example:
-//
-//	func BenchmarkRandInt(b *testing.B) {
-//	    for range b.N {
-//	        rand.Int()
-//	    }
-//	}
-//
-// In this style of benchmark, the benchmark function must run
-// the target code b.N times. The benchmark function is called
-// multiple times with b.N adjusted until the benchmark function
-// lasts long enough to be timed reliably. This also means any setup
-// done before the loop may be run several times.
-//
-// If a benchmark needs some expensive setup before running, the timer
-// should be explicitly reset:
-//
-//	func BenchmarkBigLen(b *testing.B) {
-//	    big := NewBig()
-//	    b.ResetTimer()
-//	    for range b.N {
-//	        big.Len()
-//	    }
-//	}
-//
-// New benchmarks should prefer using [B.Loop], which is more robust
-// and more efficient.
-//
-// # Examples
-//
-// The package also runs and verifies example code. Example functions may
-// include a concluding line comment that begins with "Output:" and is compared with
-// the standard output of the function when the tests are run. (The comparison
-// ignores leading and trailing space.) These are examples of an example:
-//
-//	func ExampleHello() {
-//	    fmt.Println("hello")
-//	    // Output: hello
-//	}
-//
-//	func ExampleSalutations() {
-//	    fmt.Println("hello, and")
-//	    fmt.Println("goodbye")
-//	    // Output:
-//	    // hello, and
-//	    // goodbye
-//	}
-//
-// The comment prefix "Unordered output:" is like "Output:", but matches any
-// line order:
-//
-//	func ExamplePerm() {
-//	    for _, value := range Perm(5) {
-//	        fmt.Println(value)
-//	    }
-//	    // Unordered output: 4
-//	    // 2
-//	    // 1
-//	    // 3
-//	    // 0
-//	}
-//
-// Example functions without output comments are compiled but not executed.
-//
-// The naming convention to declare examples for the package, a function F, a type T and
-// method M on type T are:
-//
-//	func Example() { ... }
-//	func ExampleF() { ... }
-//	func ExampleT() { ... }
-//	func ExampleT_M() { ... }
-//
-// Multiple example functions for a package/type/function/method may be provided by
-// appending a distinct suffix to the name. The suffix must start with a
-// lower-case letter.
-//
-//	func Example_suffix() { ... }
-//	func ExampleF_suffix() { ... }
-//	func ExampleT_suffix() { ... }
-//	func ExampleT_M_suffix() { ... }
-//
-// The entire test file is presented as the example when it contains a single
-// example function, at least one other function, type, variable, or constant
-// declaration, and no test or benchmark functions.
-//
-// # Fuzzing
-//
-// 'go test' and the testing package support fuzzing, a testing technique where
-// a function is called with randomly generated inputs to find bugs not
-// anticipated by unit tests.
-//
-// Functions of the form
-//
-//	func FuzzXxx(*testing.F)
-//
-// are considered fuzz tests.
-//
-// For example:
-//
-//	func FuzzHex(f *testing.F) {
-//	  for _, seed := range [][]byte{{}, {0}, {9}, {0xa}, {0xf}, {1, 2, 3, 4}} {
-//	    f.Add(seed)
-//	  }
-//	  f.Fuzz(func(t *testing.T, in []byte) {
-//	    enc := hex.EncodeToString(in)
-//	    out, err := hex.DecodeString(enc)
-//	    if err != nil {
-//	      t.Fatalf("%v: decode: %v", in, err)
-//	    }
-//	    if !bytes.Equal(in, out) {
-//	      t.Fatalf("%v: not equal after round trip: %v", in, out)
-//	    }
-//	  })
-//	}
-//
-// A fuzz test maintains a seed corpus, or a set of inputs which are run by
-// default, and can seed input generation. Seed inputs may be registered by
-// calling (*F).Add or by storing files in the directory testdata/fuzz/<Name>
-// (where <Name> is the name of the fuzz test) within the package containing
-// the fuzz test. Seed inputs are optional, but the fuzzing engine may find
-// bugs more efficiently when provided with a set of small seed inputs with good
-// code coverage. These seed inputs can also serve as regression tests for bugs
-// identified through fuzzing.
-//
-// The function passed to (*F).Fuzz within the fuzz test is considered the fuzz
-// target. A fuzz target must accept a *T parameter, followed by one or more
-// parameters for random inputs. The types of arguments passed to (*F).Add must
-// be identical to the types of these parameters. The fuzz target may signal
-// that it's found a problem the same way tests do: by calling T.Fail (or any
-// method that calls it like T.Error or T.Fatal) or by panicking.
-//
-// When fuzzing is enabled (by setting the -fuzz flag to a regular expression
-// that matches a specific fuzz test), the fuzz target is called with arguments
-// generated by repeatedly making random changes to the seed inputs. On
-// supported platforms, 'go test' compiles the test executable with fuzzing
-// coverage instrumentation. The fuzzing engine uses that instrumentation to
-// find and cache inputs that expand coverage, increasing the likelihood of
-// finding bugs. If the fuzz target fails for a given input, the fuzzing engine
-// writes the inputs that caused the failure to a file in the directory
-// testdata/fuzz/<Name> within the package directory. This file later serves as
-// a seed input. If the file can't be written at that location (for example,
-// because the directory is read-only), the fuzzing engine writes the file to
-// the fuzz cache directory within the build cache instead.
-//
-// When fuzzing is disabled, the fuzz target is called with the seed inputs
-// registered with F.Add and seed inputs from testdata/fuzz/<Name>. In this
-// mode, the fuzz test acts much like a regular test, with subtests started
-// with F.Fuzz instead of T.Run.
-//
-// See https://go.dev/doc/fuzz for documentation about fuzzing.
-//
-// # Skipping
-//
-// Tests or benchmarks may be skipped at run time with a call to
-// the Skip method of *T or *B:
-//
-//	func TestTimeConsuming(t *testing.T) {
-//	    if testing.Short() {
-//	        t.Skip("skipping test in short mode.")
-//	    }
-//	    ...
-//	}
-//
-// The Skip method of *T can be used in a fuzz target if the input is invalid,
-// but should not be considered a failing input. For example:
-//
-//	func FuzzJSONMarshaling(f *testing.F) {
-//	    f.Fuzz(func(t *testing.T, b []byte) {
-//	        var v interface{}
-//	        if err := json.Unmarshal(b, &v); err != nil {
-//	            t.Skip()
-//	        }
-//	        if _, err := json.Marshal(v); err != nil {
-//	            t.Errorf("Marshal: %v", err)
-//	        }
-//	    })
-//	}
-//
-// # Subtests and Sub-benchmarks
-//
-// The Run methods of T and B allow defining subtests and sub-benchmarks,
-// without having to define separate functions for each. This enables uses
-// like table-driven benchmarks and creating hierarchical tests.
-// It also provides a way to share common setup and tear-down code:
-//
-//	func TestFoo(t *testing.T) {
-//	    // <setup code>
-//	    t.Run("A=1", func(t *testing.T) { ... })
-//	    t.Run("A=2", func(t *testing.T) { ... })
-//	    t.Run("B=1", func(t *testing.T) { ... })
-//	    // <tear-down code>
-//	}
-//
-// Each subtest and sub-benchmark has a unique name: the combination of the name
-// of the top-level test and the sequence of names passed to Run, separated by
-// slashes, with an optional trailing sequence number for disambiguation.
-//
-// The argument to the -run, -bench, and -fuzz command-line flags is an unanchored regular
-// expression that matches the test's name. For tests with multiple slash-separated
-// elements, such as subtests, the argument is itself slash-separated, with
-// expressions matching each name element in turn. Because it is unanchored, an
-// empty expression matches any string.
-// For example, using "matching" to mean "whose name contains":
-//
-//	go test -run ''        # Run all tests.
-//	go test -run Foo       # Run top-level tests matching "Foo", such as "TestFooBar".
-//	go test -run Foo/A=    # For top-level tests matching "Foo", run subtests matching "A=".
-//	go test -run /A=1      # For all top-level tests, run subtests matching "A=1".
-//	go test -fuzz FuzzFoo  # Fuzz the target matching "FuzzFoo"
-//
-// The -run argument can also be used to run a specific value in the seed
-// corpus, for debugging. For example:
-//
-//	go test -run=FuzzFoo/9ddb952d9814
-//
-// The -fuzz and -run flags can both be set, in order to fuzz a target but
-// skip the execution of all other tests.
-//
-// Subtests can also be used to control parallelism. A parent test will only
-// complete once all of its subtests complete. In this example, all tests are
-// run in parallel with each other, and only with each other, regardless of
-// other top-level tests that may be defined:
-//
-//	func TestGroupedParallel(t *testing.T) {
-//	    for _, tc := range tests {
-//	        tc := tc // capture range variable
-//	        t.Run(tc.Name, func(t *testing.T) {
-//	            t.Parallel()
-//	            ...
-//	        })
-//	    }
-//	}
-//
-// Run does not return until parallel subtests have completed, providing a way
-// to clean up after a group of parallel tests:
-//
-//	func TestTeardownParallel(t *testing.T) {
-//	    // This Run will not return until the parallel tests finish.
-//	    t.Run("group", func(t *testing.T) {
-//	        t.Run("Test1", parallelTest1)
-//	        t.Run("Test2", parallelTest2)
-//	        t.Run("Test3", parallelTest3)
-//	    })
-//	    // <tear-down code>
-//	}
-//
-// # Main
-//
-// It is sometimes necessary for a test or benchmark program to do extra setup or teardown
-// before or after it executes. It is also sometimes necessary to control
-// which code runs on the main thread. To support these and other cases,
-// if a test file contains a function:
-//
-//	func TestMain(m *testing.M)
-//
-// then the generated test will call TestMain(m) instead of running the tests or benchmarks
-// directly. TestMain runs in the main goroutine and can do whatever setup
-// and teardown is necessary around a call to m.Run. m.Run will return an exit
-// code that may be passed to os.Exit. If TestMain returns, the test wrapper
-// will pass the result of m.Run to os.Exit itself.
-//
-// When TestMain is called, flag.Parse has not been run. If TestMain depends on
-// command-line flags, including those of the testing package, it should call
-// flag.Parse explicitly. Command line flags are always parsed by the time test
-// or benchmark functions run.
-//
-// A simple implementation of TestMain is:
-//
-//	func TestMain(m *testing.M) {
-//		// call flag.Parse() here if TestMain uses flags
-//		m.Run()
-//	}
-//
-// TestMain is a low-level primitive and should not be necessary for casual
-// testing needs, where ordinary test functions suffice.

+// An appropriate use of a Pool is to manage a group of temporary items

+// Package tls provides generic thread-local storage backed by POSIX pthread
+// TLS. When built with the GC-enabled configuration (llgo && !nogc), TLS slots
+// are automatically registered with the BDWGC garbage collector so pointers
+// stored in thread-local state remain visible to the collector. Builds without
+// GC integration (llgo && nogc) simply fall back to pthread TLS without root
+// registration.
+//
+// Basic usage:
+//
+//	h := tls.Alloc[int](nil)
+//	h.Set(42)
+//	val := h.Get() // returns 42
+//
+// With destructor:
+//
+//	h := tls.Alloc[*Resource](func(r **Resource) {
+//	    if r != nil && *r != nil {
+//	        (*r).Close()
+//	    }
+//	})
+//
+// Build tags:
+//   - llgo && !nogc: Enables GC-aware slot registration via BDWGC
+//   - llgo && nogc:  Disables GC integration; TLS acts as plain pthread TLS

+/* Dynamically-loaded libunwind for fault-site C stacks.
+ *
+ * The FP-walk in unwind_llgo.go breaks on C frames compiled without frame
+ * pointers, and on linux dladdr cannot name non-dynamic C symbols. This
+ * code resolves libunwind AT RUNTIME (dlopen/dlsym at handler-install
+ * time — never in the signal handler itself; no link-time -lunwind) and
+ * unwinds the fault ucontext with DWARF/compact unwind info, resuming with
+ * the FP chain where unwind info runs out.
+ *
+ * Flavors probed, in order:
+ *   darwin: unw_* live in libSystem — dlsym(RTLD_DEFAULT), no dlopen.
+ *           unw_context_t is a register buffer (LLVM layout); we translate
+ *           the mcontext thread state into it.
+ *   linux:  1) nongnu libunwind (libunwind.so.8): symbols are arch-prefixed
+ *              (_ULx86_64_* / _ULaarch64_*); unw_init_local accepts the
+ *              signal ucontext_t directly, and unw_get_proc_name reads
+ *              .symtab so static C symbols get named.
+ *           2) LLVM libunwind (libunwind.so.1): plain unw_* symbols;
+ *              context translated like darwin.
+ *
+ * Async-signal-safety: dlopen/dlsym/getenv happen once at init. In the
+ * handler only unw_init_local(2)/unw_step/unw_get_reg run; nongnu libunwind
+ * documents these as thread-safe and usable from signal handlers for local
+ * unwinding (remote/global state is only touched on first use — we do a
+ * throwaway warm-up unwind at init to pre-fault lazy state). The debug
+ * printing (snprintf/write) is for the experiment only.

-// Map is like a Go map[interface{}]interface{} but is safe for concurrent use
-// by multiple goroutines without additional locking or coordination.
-// Loads, stores, and deletes run in amortized constant time.
-//
-// The Map type is specialized. Most code should use a plain Go map instead,
-// with separate locking or coordination, for better type safety and to make it
-// easier to maintain other invariants along with the map content.
-//
-// The Map type is optimized for two common use cases: (1) when the entry for a given
-// key is only ever written once but read many times, as in caches that only grow,
-// or (2) when multiple goroutines read, write, and overwrite entries for disjoint
-// sets of keys. In these two cases, use of a Map may significantly reduce lock
-// contention compared to a Go map paired with a separate Mutex or RWMutex.
-//
-// The zero Map is empty and ready for use. A Map must not be copied after first use.
-//
-// In the terminology of the Go memory model, Map arranges that a write operation
-// “synchronizes before” any read operation that observes the effect of the write, where
-// read and write operations are defined as follows.
-// Load, LoadAndDelete, LoadOrStore, Swap, CompareAndSwap, and CompareAndDelete
-// are read operations; Delete, LoadAndDelete, Store, and Swap are write operations;
-// LoadOrStore is a write operation when it returns loaded set to false;
-// CompareAndSwap is a write operation when it returns swapped set to true;
-// and CompareAndDelete is a write operation when it returns deleted set to true.

-// ForkLock is used to synchronize creation of new file descriptors
-// with fork.
-//
-// We want the child in a fork/exec sequence to inherit only the
-// file descriptors we intend. To do that, we mark all file
-// descriptors close-on-exec and then, in the child, explicitly
-// unmark the ones we want the exec'ed program to keep.
-// Unix doesn't make this easy: there is, in general, no way to
-// allocate a new file descriptor close-on-exec. Instead you
-// have to allocate the descriptor and then mark it close-on-exec.
-// If a fork happens between those two events, the child's exec
-// will inherit an unwanted file descriptor.
-//
-// This lock solves that race: the create new fd/mark close-on-exec
-// operation is done holding ForkLock for reading, and the fork itself
-// is done holding ForkLock for writing. At least, that's the idea.
-// There are some complications.
-//
-// Some system calls that create new file descriptors can block
-// for arbitrarily long times: open on a hung NFS server or named
-// pipe, accept on a socket, and so on. We can't reasonably grab
-// the lock across those operations.
-//
-// It is worse to inherit some file descriptors than others.
-// If a non-malicious child accidentally inherits an open ordinary file,
-// that's not a big deal. On the other hand, if a long-lived child
-// accidentally inherits the write end of a pipe, then the reader
-// of that pipe will not see EOF until that child exits, potentially
-// causing the parent program to hang. This is a common problem
-// in threaded C programs that use popen.
-//
-// Luckily, the file descriptors that are most important not to
-// inherit are not the ones that can take an arbitrarily long time
-// to create: pipe returns instantly, and the net package uses
-// non-blocking I/O to accept on a listening socket.
-// The rules for which file descriptor-creating operations use the
-// ForkLock are as follows:
-//
-//   - Pipe. Use pipe2 if available. Otherwise, does not block,
-//     so use ForkLock.
-//   - Socket. Use SOCK_CLOEXEC if available. Otherwise, does not
-//     block, so use ForkLock.
-//   - Open. Use O_CLOEXEC if available. Otherwise, may block,
-//     so live with the race.
-//   - Dup. Use F_DUPFD_CLOEXEC or dup3 if available. Otherwise,
-//     does not block, so use ForkLock.

-// These are predefined layouts for use in Time.Format and time.Parse.
-// The reference time used in these layouts is the specific time stamp:
-//
-//	01/02 03:04:05PM '06 -0700
-//
-// (January 2, 15:04:05, 2006, in time zone seven hours west of GMT).
-// That value is recorded as the constant named Layout, listed below. As a Unix
-// time, this is 1136239445. Since MST is GMT-0700, the reference would be
-// printed by the Unix date command as:
-//
-//	Mon Jan 2 15:04:05 MST 2006
-//
-// It is a regrettable historic error that the date uses the American convention
-// of putting the numerical month before the day.
-//
-// The example for Time.Format demonstrates the working of the layout string
-// in detail and is a good reference.
-//
-// Note that the RFC822, RFC850, and RFC1123 formats should be applied
-// only to local times. Applying them to UTC times will use "UTC" as the
-// time zone abbreviation, while strictly speaking those RFCs require the
-// use of "GMT" in that case.
-// In general RFC1123Z should be used instead of RFC1123 for servers
-// that insist on that format, and RFC3339 should be preferred for new protocols.
-// RFC3339, RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting;
-// when used with time.Parse they do not accept all the time formats
-// permitted by the RFCs and they do accept time formats not formally defined.
-// The RFC3339Nano format removes trailing zeros from the seconds field
-// and thus may not sort correctly once formatted.
-//
-// Most programs can use one of the defined constants as the layout passed to
-// Format or Parse. The rest of this comment can be ignored unless you are
-// creating a custom layout string.
-//
-// To define your own format, write down what the reference time would look like
-// formatted your way; see the values of constants like ANSIC, StampMicro or
-// Kitchen for examples. The model is to demonstrate what the reference time
-// looks like so that the Format and Parse methods can apply the same
-// transformation to a general time value.
-//
-// Here is a summary of the components of a layout string. Each element shows by
-// example the formatting of an element of the reference time. Only these values
-// are recognized. Text in the layout string that is not recognized as part of
-// the reference time is echoed verbatim during Format and expected to appear
-// verbatim in the input to Parse.
-//
-//	Year: "2006" "06"
-//	Month: "Jan" "January" "01" "1"
-//	Day of the week: "Mon" "Monday"
-//	Day of the month: "2" "_2" "02"
-//	Day of the year: "__2" "002"
-//	Hour: "15" "3" "03" (PM or AM)
-//	Minute: "4" "04"
-//	Second: "5" "05"
-//	AM/PM mark: "PM"
-//
-// Numeric time zone offsets format as follows:
-//
-//	"-0700"     ±hhmm
-//	"-07:00"    ±hh:mm
-//	"-07"       ±hh
-//	"-070000"   ±hhmmss
-//	"-07:00:00" ±hh:mm:ss
-//
-// Replacing the sign in the format with a Z triggers
-// the ISO 8601 behavior of printing Z instead of an
-// offset for the UTC zone. Thus:
-//
-//	"Z0700"      Z or ±hhmm
-//	"Z07:00"     Z or ±hh:mm
-//	"Z07"        Z or ±hh
-//	"Z070000"    Z or ±hhmmss
-//	"Z07:00:00"  Z or ±hh:mm:ss
-//
-// Within the format string, the underscores in "_2" and "__2" represent spaces
-// that may be replaced by digits if the following number has multiple digits,
-// for compatibility with fixed-width Unix time formats. A leading zero represents
-// a zero-padded value.
-//
-// The formats __2 and 002 are space-padded and zero-padded
-// three-character day of year; there is no unpadded day of year format.
-//
-// A comma or decimal point followed by one or more zeros represents
-// a fractional second, printed to the given number of decimal places.
-// A comma or decimal point followed by one or more nines represents
-// a fractional second, printed to the given number of decimal places, with
-// trailing zeros removed.
-// For example "15:04:05,000" or "15:04:05.000" formats or parses with
-// millisecond precision.
-//
-// Some valid layouts are invalid time values for time.Parse, due to formats
-// such as _ for space padding and Z for zone information.

+# Manual caller-info acceptance playground
+
+Each directory runs under both `go` and `llgo` for side-by-side comparison.
+Every scenario also has an automated regression in `test/go`
+(`caller_acceptance_test.go`); this playground exists for eyeballing real
+output. From the repository root:
+
+    export LLGO_ROOT=$(git rev-parse --show-toplevel)
+    go build -o /tmp/llgo ./cmd/llgo    # or: go run ./cmd/llgo ...
+
+Conformance bar: output format and user-code file:line match gc exactly;
+runtime-internal, patched-stdlib and startup frames may differ.
+
+## panic — Go-style traceback for an unrecovered panic
+    cd test/_manualtest/panic
+    go run .            # gc's goroutine traceback
+    /tmp/llgo run .     # same shape: names + file:line + offset (exit 2)
+
+## logging — log.Lshortfile / slog AddSource
+    cd test/_manualtest/logging
+    go run . && /tmp/llgo run .    # the main.go:NN locations must agree
+
+## callers — Caller ladder / CallersFrames / FuncForPC panorama
+    cd test/_manualtest/callers
+    go run . > /tmp/gc.txt; /tmp/llgo run . > /tmp/llgo.txt
+    diff /tmp/gc.txt /tmp/llgo.txt
+    # line columns must agree; known diffs: runtime-internal frame lines,
+    # gc's runtime.main/goexit tail frames
+
+## testfail — llgo test failure locations
+    cd test/_manualtest/testfail
+    go test .           # x_test.go:NN: boom
+    /tmp/llgo test .    # the same x_test.go:NN: boom
+
+## cexcept — hardware faults in C code called from Go
+    cd test/_manualtest/cexcept
+    /tmp/llgo run . segv recover     # NULL store in C: recover works, prints
+                                     # the post-recover stack
+    /tmp/llgo run . segv norecover   # unrecovered: panic + gc-style traceback
+                                     # (fault-site frames pending the
+                                     # panic-snapshot follow-up)
+    /tmp/llgo run . div recover      # arm64 integer division does not trap
+                                     # (hardware returns 0); amd64 raises
+                                     # SIGFPE
+
+Verified (darwin/arm64 + linux/arm64 + linux/amd64):
+- SIGSEGV/SIGBUS/SIGFPE in a C frame convert to Go panics (gc's exact
+  error texts); recover works, and the fault-site stack — C frames down
+  through the Go callers — appears in recovered `debug.Stack()` and in
+  unrecovered tracebacks (panic pc snapshot captured from the signal
+  ucontext, FP chain walked from the interrupted frame; C is compiled
+  with -fno-omit-frame-pointer so x86-64 chains hold).
+- Known limitations:
+  1. On linux, C frames may display under a neighboring Go function's
+     name: dladdr only sees dynamic symbols there, so the nearest-below
+     table attribution cannot be cross-checked (darwin names C frames
+     correctly via dladdr). Pre-existing for any C pc between Go
+     functions; the link-phase hole-sentinel follow-up fixes naming and
+     misattribution together.
+  2. No sigaltstack: on stack overflow the handler cannot run and the
+     process dies (gc prints "stack overflow"). Note that C-side UB gets
+     propagated by clang (this test was once optimized into infinite
+     recursion); wrap/fault.c uses a volatile pointer to prevent that.

+// Bug: nested shift with untyped constant
+//
+// When a shift expression `(1 << byteVar)` is used as the right operand
+// of another shift expression, SSA generates `1:untyped int << byteVar`
+// with type `untyped int`, which violates SSA sanity checks.
+//
+// SSA output for nested shift expressions:
+//   t2 = 1:untyped int << t1                                    untyped int  ← BUG
+//   t3 = convert uint <- untyped int (t2)                              uint
+//   t4 = 1:uint32 << t3                                              uint32
+//
+// The bug causes SSA sanity check to fail when compiling:
+//   value << (1 << bytes[3])
+// but NOT when an explicit conversion is used:
+//   uint(1 << bytes[3])
+// because the conversion forces type resolution before SSA construction.

+# GOROOT Runner
+
+This package runs selected upstream `GOROOT/test` cases against `llgo` without
+copying the upstream source files into this repository.
+
+The source of truth is an external `GOROOT`. Upstream files stay read-only;
+each case runs in a temporary workspace.
+
+Directive modes:
+
+- `legacy`: `run`
+- `ci`: `run`, `runoutput`, and `buildrun`
+- `runlike`: all runnable single-file and directory directives
+- `coverage`: recursively discovers and executes `compile`, `errorcheck`,
+  `errorcheckandrundir`, `run`, `runoutput`, `rundir`, `runindir`, `buildrun`,
+  and `buildrundir`
+
+`coverage` follows the upstream test runner's directive and compiler flag
+conventions. Compile-only and diagnostic cases are executed, not omitted from
+the coverage total. Known failures remain executed and are classified through
+`xfail.yaml`. Cases that exercise gc-specific or otherwise inapplicable
+behavior are classified separately through `notapplicable.yaml`, so the xfail
+count continues to represent remaining LLGo compatibility work. Only
+explicitly host-unsafe cases are skipped. Each not-applicable entry documents
+both the toolchain-specific mechanism under test and why the corresponding
+behavior is not an LLGo compatibility goal.
+
+Basic usage:
+
+```bash
+go test ./test/goroot -count=1 -args \
+  -goroot "$(go env GOROOT)" \
+  -dirs . \
+  -case '^helloworld\.go$'
+```
+
+Resource-constrained full coverage:
+
+```bash
+GOMAXPROCS=2 go test -p=1 ./test/goroot -count=1 -timeout=180m -args \
+  -goroot "$(go env GOROOT)" \
+  -directive-mode coverage \
+  -max-rss-mib 1536 \
+  -rss-warn-mib 768 \
+  -min-memory-free-percent 20 \
+  -min-swap-free-mib 1024
+```
+
+On Unix, the RSS limit covers the complete process group and terminates the
+group when exceeded. System memory and swap are checked before and during every
+child command. Resource guard failures cannot be converted into expected
+failures by `xfail.yaml`.
+
+Multiple toolchains:
+
+```bash
+bash ./dev/test_goroot.sh /path/to/go1.23 /path/to/go1.24 -- -dirs . -case '^helloworld\.go$'
+```
+
+Useful flags:
+
+- `-goroot`: upstream Go toolchain root to read tests from
+- `-go`: baseline `go` binary; defaults to `<goroot>/bin/go`
+- `-llgo`: existing `llgo` binary to use; otherwise one is built from the current checkout
+- `-dirs`: comma-separated `GOROOT/test` subdirectories to scan
+- `-case`: regexp filter on the relative case path
+- `-directive-mode`: case discovery mode: `legacy`, `ci`, `runlike`, or `coverage`
+- `-directives`: comma-separated directive filter within the selected mode
+- `-limit`: stop after N matching cases
+- `-shard-index`: 0-based shard index used to partition matching cases
+- `-shard-total`: total number of shards used to partition matching cases
+- `-keepwork`: keep the temporary symlink work tree for debugging
+- `-build-timeout`: timeout for each build or compile step
+- `-run-timeout`: timeout for each compiled program run
+- `-list-cases`: print selected totals without building or running cases
+- `-list-case-paths`: print selected directives and paths without running cases
+- `-max-rss-mib`: hard process-group RSS limit; `0` disables it
+- `-rss-warn-mib`: log commands whose observed peak RSS reaches this value
+- `-rss-poll`: process-group RSS sampling interval
+- `-min-memory-free-percent`: minimum system free-memory percentage
+- `-min-swap-free-mib`: minimum free swap in MiB
+- `-memory-pressure-poll`: system memory and swap sampling interval
+- `-xfail`: xfail YAML file, relative to repo root by default
+- `-not-applicable`: not-applicable YAML file, relative to repo root by default

+# Standard Library Compatibility Tests
+
+This directory contains compatibility tests for the Go standard library on llgo. These tests ensure that llgo's libc-backed implementations conform to the Go standard library specification across the pinned supported CI toolchains (Go 1.25 and Go 1.26).
+
+## Directory Structure
+
+```
+test/std/
+├── README.md           # This file
+├── math/
+│   ├── math_test.go         # Core math tests (no build tags)
+│   ├── math_go124_test.go   # Go 1.24+ specific tests
+│   ├── math_bench_test.go   # Performance benchmarks
+│   └── testdata/            # Test fixtures (if needed)
+└── ... other packages
+```
+
+## Test Organization
+
+### Package Structure
+
+Each standard library package should have its own subdirectory under `test/std/`. For example:
+- `test/std/math/` - tests for the `math` package
+- `test/std/strings/` - tests for the `strings` package
+- `test/std/io/` - tests for the `io` package
+
+### File Naming Conventions
+
+- **`<package>_test.go`**: Core tests that run on both `go test` and `llgo test`. These files should NOT have `//go:build llgo` tags so they validate compatibility with standard Go.
+
+- **`<package>_go1XX_test.go`**: Version-specific tests for Go 1.XX+ APIs. Use build tags like `//go:build go1.24` to gate features only available in newer Go versions.
+
+- **`<package>_bench_test.go`**: Benchmarks for performance-sensitive functions. At least one benchmark is recommended per package.
+
+- **`testdata/`**: Directory for test fixtures, golden files, or other test data.
+
+## Build Tags
+
+### Standard Tests (no tags)
+
+Core functionality tests should NOT use `//go:build llgo` tags:
+
+```go
+package math_test
+
+import (
+	"math"
+	"testing"
+)
+
+func TestSqrt(t *testing.T) {
+	result := math.Sqrt(4.0)
+	if result != 2.0 {
+		t.Errorf("Sqrt(4.0) = %v, want 2.0", result)
+	}
+}
+```
+
+This ensures both `go test` and `llgo test` exercise the same test suite.
+
+### Version-Specific Tests
+
+For APIs introduced in Go 1.24 or later:
+
+```go
+//go:build go1.24
+// +build go1.24
+
+package math_test
+
+import "testing"
+
+func TestNewGo124API(t *testing.T) {
+	// Test Go 1.24+ specific functionality
+}
+```
+
+### llgo-Specific Tests
+
+Tests that require llgo-specific runtime features belong in `test/c/` (and other language-specific directories as they are added), not here. Those tests use `//go:build llgo` tags.
+
+## Documenting Unsupported Features
+
+If llgo doesn't yet support a feature, use `t.Skip()` with a TODO identifier:
+
+```go
+func TestUnsupportedFeature(t *testing.T) {
+	t.Skip("TODO(issue-1234): implement feature X in llgo runtime")
+	// Test code here
+}
+```
+
+This allows:
+1. Tests to be written before full implementation
+2. Clear tracking of what's missing
+3. Easy identification of work items for contributors
+
+## Adding Benchmarks
+
+Performance-sensitive packages should include at least one benchmark:
+
+```go
+func BenchmarkSqrt(b *testing.B) {
+	x := 2.0
+	for i := 0; i < b.N; i++ {
+		math.Sqrt(x)
+	}
+}
+```
+
+Run benchmarks with:
+```bash
+go test -bench=. ./test/std/math/
+# or with llgo
+llgo test -bench=. ./test/std/math/
+```
+
+## Running Tests
+
+### Standard Go
+
+```bash
+# Run all stdlib compatibility tests
+go test ./test/std/...
+
+# Run specific package tests
+go test ./test/std/math/
+
+# Run tests in short mode
+go test -short ./test/std/...
+
+# Run benchmarks
+go test -bench=. ./test/std/math/
+```
+
+### llgo
+
+```bash
+# Run all tests (requires LLGO_ROOT environment variable)
+./dev/llgo.sh test ./test/...
+
+# Or with installed llgo
+llgo test ./test/...
+
+# Run specific package
+llgo test ./test/std/math/
+```
+
+## Contributing New Package Tests
+
+1. **Create package directory**: `mkdir test/std/<package>`
+
+2. **Write core tests**: Create `<package>_test.go` with functional test cases
+
+3. **Add benchmarks**: Create `<package>_bench_test.go` with at least one benchmark
+
+4. **Handle version differences**: If needed, create `<package>_go1XX_test.go` files
+
+5. **Document gaps**: Use `t.Skip("TODO: ...")` for unsupported features
+
+6. **Update tracking**: Add entry to `test/std/TODO.md`
+
+7. **Validate**: Ensure tests pass with both `go test` and `llgo test`
+
+## Test Coverage Goals
+
+Focus on:
+- **Core functionality**: Cover main API surface area
+- **Edge cases**: Boundary conditions, special values (NaN, Inf, zero)
+- **Error conditions**: Invalid inputs, error paths
+- **Performance**: Key hot-path functions
+- **Compatibility**: Behavior matches standard Go across versions
+
+## Related Directories
+
+- **`test/c/`**: llgo-specific C interop tests (uses `//go:build llgo`)
+- **`_cmptest/`**: Comparison tests ensuring Go/llgo output equivalence
+
+The `test/std/` suite focuses on validating standard library API conformance, while `_cmptest/` validates behavioral equivalence through end-to-end comparison.
