Pull request overview
Optimizes EVM BYTE opcode lowering in the MIR builder to reduce instruction count and improve constant-folding, aiming to speed up compilation and/or generated code for BYTE usage.
Changes:
- Adds constant-folding paths for
BYTEwhenindex(and optionallyvalue) is constant. - Replaces bit-shift/div/mod-by-64 logic with byte-granular arithmetic (
/8,%8) using shifts and masks. - Introduces a two-level select tree to choose the source 64-bit limb with shorter live ranges.
