[PATCH] D83024: [PGO] Instrument function entry BB by default in IR PGO

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

Here version is overloaded with different meanings: 1) to indicate format change; 2) to indicate instrumentation compiler version that is capable of producing this format.  These two purposes can be contradicting to each other  as the user can use option to force the old format with the new compiler.

I am not sure how compiler can relax the check at the profile use time.
