> @madhur13490 can you provide information about the three stages (i.e., relevant cmake flags for all stages like llvm-projects/runtime, flags to customize openmp build/install paths)? Additionall, information about the location of omp.h before this patch and with this patch might be helpful to understand the problem.

`omp.h` is moved from `lib/clang/22/include/omp.h` to `include/omp.h`. 

We use standard 3-stage LTO-PGO-BOLT builds, which primarily use https://github.com/llvm/llvm-project/blob/main/clang/cmake/caches/BOLT-PGO.cmake. You can find top-level community doc at https://llvm.org/docs/AdvancedBuilds.html
