URL: https://github.com/llvm/llvm-project/commit/ba9590d8bc76f9d410a626c26a3d55e1381de4aa DIFF: https://github.com/llvm/llvm-project/commit/ba9590d8bc76f9d410a626c26a3d55e1381de4aa.diff LOG: [Clang][Docs] Add help test to `-march` and `-mcpu` to suggest `-mcpu=help` Currently there is no documentation for these flags, users might find it confusing to know which values are permitted. This change simply adds documentation to suggest using `-mcpu=help` to list the availible target names.
