There was a problem hiding this comment.
I shared my opinion on a related proposal here: riscv-non-isa/riscv-c-api-doc#73 (comment)
I don't personally plan to use these flags, so I'm OK if it remains GCC-specific behavior, but I won't fight it if others in the community think it's actually useful.

…. Alias -m[no-]strict-align to scalar. __riscv_misaligned_fast will be set based on -mno-scalar-strict-align or -mno-strict-align. This matches the direction gcc is proposing.

Add two new option `-m[no-]scalar-strict-align` for alias of `-m[no-]-strict-align` and `-m[no-][vector]-strict-align` for vector misaligned access.
