Subject: [PATCH] AArch64: Remove redundant check in aarch64_simd_mov
The split condition in aarch64_simd_mov uses aarch64_simd_special_constant_p.
While doing the split, it checks the mode before calling
aarch64_maybe_generate_simd_constant. This risky since it may result in
unexpectedly calling aarch64_split_simd_move instead of
aarch64_maybe_generate_simd_constant. Since the mode is already checked,
remove the spurious explicit mode check.
gcc/ChangeLog:
* config/aarch64/aarch64-simd.md (aarch64_simd_mov<VQMOV:mode>):
Remove redundant mode check.
