One wart are the int64x1_t comparisons that this patch doesn't touch. Those are a bit trickier because they have define_insn_and_split mechanisms for falling back to GP reg comparisons after reload and I don't think a simple annotation will catch those cases correctly. Those will need more custom thinking. As said, this patch doesn't touch those and is a decent straightforward improvement on its own. Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf. gcc/ChangeLog: PR target/99195 * config/aarch64/aarch64-simd.md (aarch64_cm<optab><mode>): Rename to...
