Using magic-trace profiles for Profile-Guided Optimization (PGO)

[zamazan4ik]

Hi!

I want to use magic-trace profiles for performing Profile-Guided Optimization (PGO) for my apps. Since magic-trace is perf-based I assume that I can try to convert magic-trace profiles with https://github.com/google/autofdo tooling to perform PGO optimization with https://clang.llvm.org/docs/UsersManual.html#using-sampling-profilers (Clang instructions).

Did anyone try to do something similar before? I want try to use exactly magic-trace profiles since we are already using magic-trace and we don't want to bring to our landscape an additional tool.

Would be great if anyone could clarify the question. If the magic-trace profile is fully compatible with perf format, I guess it shouldn't be a problem.
