[PATCH] D58737: [InstrProf] Use separate comdat group for data and counters

[Vedant Kumar via Phabricator via llvm-commits]

vsk added a comment.

I'm confused by this wording re: comdats in the LangRef: "All global objects that specify this key will only end up in the final object file if the linker chooses that key over some other key". Why can multiple global objects with the same comdat key end up in the final object file?

Also, why is the selection kind here 'any' instead of 'exactmatch'? If the counter array sizes legitimately can vary (why?), then wouldn't we want 'largestsize'?
