Is it expected that we run this pass in the default -O1/-O2 pipeline?
I thought this was enabled only when -fprofile-instr-{generate/use} is specified.

check PGOOpt && !PGOOpt->ProfileUseFile.empty()

Thanks for the review. Here is the updated patch.

Don't we have a test for this? We should (I thought the PGO pipeline was tested, if it's not, you can probably add a test in a follow-up)

Should checkProfileUseFile instead of SampleProfileFile.

Updated the patch with review comments.

@davidxl: I meant to use PGOOpt->SampleProfileFile.empty(), instead of !PGOOpt->SampleProfileFile.empty().
But !PGOOpt->ProfileUseFile.empty() is definitely better here.

@davide: Added the check in PGO use pipeline.

Thanks!
