[PATCH v4 0/3] target/loongarch: Improve feature gating for instruction translation

Posted by WANG Rui 7 months ago

This series refines feature gating for LoongArch instruction translation
in TCG to improve correctness and configurability.

v4:
 - Split into smaller patches for clarity and easier review.

WANG Rui (3):
  target/loongarch: Add CRC feature flag and use it to gate CRC
    instructions
  target/loongarch: Guard BCEQZ/BCNEZ instructions with FP feature
  target/loongarch: Guard 64-bit-only insn translation with TRANS64
    macro
