[PI][HIP] warning: Linking two modules of different target triples: amdgcn-unknown-amdhsa and amdgcn-amd-amdhsa

[TejaX-Alaghari]

While compiling a simple SYCL code with LLVM for HIP backend, the following warning was reported:

warning: linking module 'llvm/build/install/lib/clang/16.0.0/../../clc/remangled-l64-signed_char.libspirv-amdgcn--amdhsa.bc': Linking two modules of different target triples: 'llvm/build/install/lib/clang/16.0.0/../../clc/remangled-l64-signed_char.libspirv-amdgcn--amdhsa.bc' is 'amdgcn-unknown-amdhsa' whereas 'hip_interop_test_rocblas.cpp' is 'amdgcn-amd-amdhsa'

What is this warning about and how can this warning be suppressed from the code?

This is because of how libclc is built, and is really something we need to fix in DPC++.

I'm not aware of a way to suppress it but it's safe to ignore for now.
