[PATCH] D145591: [clang][HIP][OpenMP] Add warning if mixed HIP / OpenMP offloading

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added a comment.

HIP toolchain does not pass -fopenmp-targets=amdgcn-amd-amdhsa to clang -cc1 in host compilation. It does not pass -fopenmp-is-device to clang -cc1 in device compilation. Without these options clang will not generate OpenMP offloading code for amdgpu in device and host compilation. The host code should still function correctly.

I tend to emit warning instead of error. I am concerned that emitting error may cause regressions in existing HIP applications whereas warnings can be disabled.
