[PATCH] D104431: [lld] Add lto-pgo-warn-mismatch option

[Yolanda via Phabricator via llvm-commits]

YolandaCY added a comment.

I seems cannot reproduce the failure. I tried:

> cmake -DLLVM_ENABLE_PROJECTS=mlir -DLLVM_ENABLE_ASSERTIONS=On -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/llvm/ -DLLVM_TARGETS_TO_BUILD=X86;NVPTX;AMDGPU -DLLVM_BUILD_EXAMPLES=ON -G Ninja ../llvm
>
> ninja -j10

Is it specific to mlir build?
