[PATCH] D97585: [InstrProfiling] Use llvm.compiler.used instead of llvm.used for ELF

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Switching to compiler.used will save ~8% of PGO object file size, although these numbers are stale: https://crbug.com/1058040#c14 I filed an issue to prototype an alternative GC root object file format similar to .llvm_addrsig in an effort to capture those object file savings, and you are telling me that none of that was ever necessary!
