> I took a quick look at your patch. I think it would be preferable to make the builtins target-independent rather than implementing the builtin by the same name for multiple targets. Although I think it is very useful to support a plus-separated list for `__builtin_cpu_supports()`, I think that's probably something for a subsequent patch. We would need to figure out code generation for that - perhaps that part will have to be completely target specific.

I fully agree with you to make  `__builtin_cpu_supports()` target-independent ( and I will update my patch on top of yours ). If plus-separated format is not supported by all target then I would suggest to make SemaBuiltinCpuSupports target-dependent - it will allow me to imlement plus-separated format on AArch64 keeping  `__builtin_cpu_supports()` target-independent.
