Computing the profile wasn’t possible on Windows
FTA: But there is one problem: PGO was up until now available only on Linux.
I think they couldn’t use a profile generated on Linux because of differences in ABI and standard library.
I also think generating a profile is OS dependent because you want it to not have much of a performance impact.
