[PATCH] D108747: [llvm][ProfileData] Add a warning to indicate potentially corrupted data

[Petr Hosek via Phabricator via llvm-commits]

phosek added a comment.

Since these fields come from the binary and should be identical (profile runtime simply copies them into the raw profile),  a different approach would be to have a new subcommand in `llvm-profdata` to validate the profile against the binary to check if those fields are indeed the same, for example something like `llvm-profdata validate --object=<binary> <profile>.profraw` (alternatively it could also be just a flag, for example `llvm-profdata merge --validate=<binary> <profile>.profraw`).
