xur added a comment. This change gonna hide the missing profile for a function permanently if there is no mismatch. Like, if a user adds a new function without changing existing functions, he will never get a warning if using the old profiles.
In LLVM IR level PGO, we also find the missing profile warning sometime too verbose. We turn missing profile off by default, but not depending on mismatch. I think that is a better method. https://reviews.llvm.org/D28867 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
