… max 21 / fraction 11684671) AMSTERDAM inherited the Osaka/Prague blob parameters (target 6 / max 9 / fraction 5007716). EELS amsterdam vm/gas.py has BLOB_SCHEDULE_TARGET = 14 and BLOB_SCHEDULE_MAX = 21 (at PER_BLOB = 2^17: Gtargetblobgas = 1835008, Gmaxblobgas = 2752512) and BLOB_BASE_FEE_UPDATE_FRACTION = 11684671, matching the mainnet BPO2 blob schedule (EIP-8135 / EIP-7892) that Amsterdam starts from. Raising Gmaxblobgas from 9 to 21 blobs exposes the pre-existing missing EIP-7594 per-tx blob limit (EELS BLOB_COUNT_LIMIT = 6, fork.py:150): the blob_count_21 sub-case of invalid_max_blobs_per_tx was previously rejected by the too-small inherited block max instead of the per-tx check. Mask it in failing.llvm next to its already-masked blob_count_7/8 siblings until the per-tx limit is implemented. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
read_csv_file crashed test collection with IndexError on any blank line in failing.llvm/slow.llvm — which the fixtures-failing-list Makefile target itself can produce via its sort/sed post-processing. Skip empty rows.

Add the SLOTNUM opcode (0x4b, EIP-7843): a NullStackOp pushing the block's slot number (already parsed into <slotNumber>) at a fixed Gbase (2) cost, disassembled from byte 75 and gated on the new Ghasslotnum schedule flag (true at AMSTERDAM). Unmask the four for_amsterdam SLOTNUM conformance fixtures; two sub-cases (value/slot_zero, gas_cost/out_of_gas) remain masked pending the separate Amsterdam Csstore cold-no-op repricing (EIP-8037/8038).

Implements EIP-7843: SLOTNUM pushes the current beacon-chain slot number (from the Amsterdam header field).
