[PATCH] D130273: [clang][Driver] Handle SPARC -mcpu=native etc.

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

I notice that in gcc, -march/-mtune/-mcpu are handled in gcc/config/* and every port may have somewhat different behaviors. E.g. x86 and aarch64 are different (and I suspect x86 has the weird behavior).

Have you checked that whether this matches GCC? We need some clang/test/Driver tests for `"-cc1"{{.*}} "-target-cpu" "..."`
