Summary

Removing hip.amdgcn.bc and hc.amdgcn.bc from HIP ToolChains. These need to be removed in VDI build.

LGTM. Thanks!

Why not provide a specific list of --hip-device-lib= for VDI builds? I am not sure about defining functions inside headers instead of using a hip bc lib.

cfe/trunk/lib/Driver/ToolChains/HIP.cpp

const char *AMDGCN::Linker::constructLLVMLinkCommand(
 
   // If --hip-device-lib is not set, add the default bitcode libraries.
   if (BCLibs.empty()) {
     // Get the bc lib file name for ISA version. For example,
     // gfx803 => oclc_isa_version_803.amdgcn.bc.
     std::string ISAVerBC =
         "oclc_isa_version_" + SubArchName.drop_front(3).str() + ".amdgcn.bc";
 
-    BCLibs.append({"hip.amdgcn.bc", "hc.amdgcn.bc", "opencl.amdgcn.bc",
+    BCLibs.append({"opencl.amdgcn.bc",
                    "ockl.amdgcn.bc", "irif.amdgcn.bc", "ocml.amdgcn.bc",
                    "oclc_finite_only_off.amdgcn.bc",
                    "oclc_daz_opt_off.amdgcn.bc",
                    "oclc_correctly_rounded_sqrt_on.amdgcn.bc",
-                   "oclc_unsafe_math_off.amdgcn.bc", "hc.amdgcn.bc", ISAVerBC});
+                   "oclc_unsafe_math_off.amdgcn.bc", ISAVerBC});
   }
   for (auto Lib : BCLibs)
     addBCLib(C, Args, CmdArgs, LibraryPaths, Lib);
 
   // Add an intermediate output file.
   CmdArgs.push_back("-o");
   std::string TmpName =
       C.getDriver().GetTemporaryPath(OutputFilePrefix.str() + "-linked", "bc");
