[PATCH] D15829: [PGO] Clang Option that enables IR level PGO instrumentation

[Rong Xu via cfe-commits]

xur updated this revision to Diff 46199.
xur added a comment.

This new version implemented the usage model David proposed. We now have a cc1 option -fprofile-instrumentor={llvm | clang} to choose which instrumentation to use. The slight difference from David's proposal is that we can use this option with -fprofile-instr-use.

Thanks,

-Rong
