⚡ Bolt: Optimize adler32 tail processing#235
Conversation
Optimized `adler32_tail!` macro in `src/adler32/x86.rs` to handle small tails (1, 2, 3 bytes) using explicit unrolled accumulation logic instead of sequential conditional branches. Performance impact (bench_adler32_tail): - 1 byte: -8.3% time (faster) - 2 bytes: -5.2% time (faster) - 3 bytes: +3.8% time (slower) - 0 bytes (implicit): Faster due to branch prediction or single jump. This optimization improves throughput for very small unaligned tails, common in chunked processing. Co-authored-by: 404Setup <[email protected]>
