One of the big improvements from PGO is the integration with indirect call promotion. I would suggest something like: Improvements to ThinLTO (-flto=thin): - Integration with profile data. When available, profile data enables more accurate function importing decisions, as well as cross-module indirect call promotion. - Significant build-time and binary-size improvements when compiling with debug info (-g). https://reviews.llvm.org/D28746 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
