Summary

This PR adds a RISC-V optimized substring search path for short patterns (2 <= len(pattern) <= 32) and gates its use behind the misaligned_fast extension at build time.

The algorithm performs a byte-by-byte sliding scan over the text and compares len(pattern) bytes at each position, with length-specialized implementations to reduce overhead.

Details

Uses brute-force matching semantics: advance text pointer by 1 byte each step and test for full pattern equality.
Specializes by pattern length:

  • For < 8 bytes: uses precise MOVB/MOVW combinations to load exactly the needed bytes.
  • For >= 8 bytes: uses MOV-based overlapping chunk comparisons for faster matching.

Requires efficient unaligned memory access; fast path is enabled only when GORISCV64EXT=misaligned_fast is specified.
