@kadircet I ran the script but it seems that my check was one of the few that did not get updated (see last commit in PR), is this normal?
Here's the cmake command for the build I used:
```
cmake -G Ninja -S llvm -B static  -DBUILD_SHARED_LIBS=false -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -DCMAKE_BUILD_TYPE="Release" -DLLVM_USE_LINKER=mold -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_C_COMPILER="gcc" -DCMAKE_CXX_COMPILER="g++"
```
