I'm unable to get program guided optimization to work with the latest C+ compiler release.
llvm-prof fails with the following error:
Instrumenting project 'project'...
Error: C:\Program Files (x86)\Intel\oneAPI\compiler\2021.2.0\windows\bin\llvm-profdata.exe returned error code 1
warning: project.profraw: Unsupported instrumentation profile format version
error: No profiles could be merged.
I've tried to replace llvm-profdata with LLVM latest version, and 11.0 without success.
Thanks for your help!
