[PATCH] D71072: [PGO][PGSO] Instrument the code gen / target passes.

[Hiroshi Yamauchi via Phabricator via llvm-commits]

yamauchi added a comment.

The issue was that in AsmPrinter ORE also depends on LazyMachineBlockFrequencyInfo and *conditionally* computes MBFI. Trying to compute it twice would delete the first one and causes an access-after-free error in ORE. I think a fix would be to compute MBFI once and share it (use one from ORE if it is available and compute one otherwise.)
