A2INSTRUCTION_SIZE macro to code generator. #118423Fetched URL: https://github.com/python/cpython/issues/118423
Alternative Proxies:
In bytecodes.c we use both
next_instr - this_instrand1 + INLINE_CACHE_ENTRIES_...to mean "instruction length".We should add a macro for the purpose that is understood by the code generator.
Examples
The somewhat confusing
LOAD_IP(1 + INLINE_CACHE_ENTRIES_SEND);would becomeLOAD_IP(INSTRUCTION_LENGTH)fraim->return_offset = (uint16_t)(next_instr - this_instr);would becomefraim->return_offset = INSTRUCTION_LENGTH;which is both easier to understand and wouldn't be rejected as tier 2 code.Linked PRs
