[cfe-dev] [llvm-dev] Proposal: pull benchmark library to the LLVM main repository

[Kirill Bobyrev via cfe-dev]

Thank you very much for the feedback!

What Chandler said about test-suite totally makes sense to me since it's
also excluded from LLVM git monorepo. I will try to land benchmark library
to LLVM core repo and update it to the latest version.

I have not been doing much CMake/project structure before, but I'll start
looking into that next week. I'll reach out to Dominic if anything goes
wrong, thank you for offering assistance!

Kind regards,
Kirill Bobyrev
