URL: https://github.com/llvm/llvm-project/commit/ba7cc955662cfebb614c6a37a7341ba6072a0b70 DIFF: https://github.com/llvm/llvm-project/commit/ba7cc955662cfebb614c6a37a7341ba6072a0b70.diff LOG: [Driver] Remove ignored Flag form of -fauto-profile/-fprofile-sample-use The Flag form options are accepted and silently ignored, which can be surprising. The Eq form is supposed to be used instead, e.g. -fprofile-sample-use=a.afdo. Since we does not intend to support GCC's "fbaata.afdo" filename, just remove the two options. While here, clean up code as -fauto-profile= is an alias.
