[PATCH] D81981: [PGO] Supplement PGO profile with Sample profile

[Wei Mi via Phabricator via llvm-commits]

wmi updated this revision to Diff 273545.
wmi added a comment.

Remove the compiler part since that part will be done in https://reviews.llvm.org/D82123.

Add an option -base-scale-function so people doesn't have to always compute the scale factor for PGO/SampleFDO profiles themselves. If user knows for some function its counter value is proportional to the total count of the execution, by specifying the function through -base-scale-function, llvm-profdata will compute the scale factor based on the counter values of the function.
