[PATCH] D105981: [AMDGPU][OpenMP] Support linking of math libraries

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added inline comments.


================
Comment at: clang/lib/Driver/ToolChains/AMDGPU.cpp:831-860
   auto Kind = llvm::AMDGPU::parseArchAMDGCN(GpuArch);
   const StringRef CanonArch = llvm::AMDGPU::getArchNameAMDGCN(Kind);
   std::string LibDeviceFile = RocmInstallation.getLibDeviceFile(CanonArch);
   if (LibDeviceFile.empty()) {
     getDriver().Diag(diag::err_drv_no_rocm_device_lib) << 1 << GpuArch;
     return;
   }
----------------
I think we'd better absorb this part into the newly added function getCommonDeviceLibOptions so that we have a centralized location for determining device libs. We could use offload kind of the toolchain to differentiate between OpenCL/HIP/OpenMP.
