[PATCH] D150013: [Clang] Respect `-L` options when compiling directly for AMDGPU

[Joseph Huber via Phabricator via cfe-commits]

jhuber6 added inline comments.


================
Comment at: clang/lib/Driver/ToolChains/AMDGPU.cpp:546
   addLinkerCompressDebugSectionsOption(getToolChain(), Args, CmdArgs);
   AddLinkerInputs(getToolChain(), Inputs, Args, CmdArgs, JA);
+  Args.AddAllArgs(CmdArgs, options::OPT_L);

Good catch, we could maybe set `isCrossCompiling` to false if targeted directly by the user, e.g. `--target=amdgcn-amd-amdhsa` vs `--offload-arch`.
