Comment at: lib/Driver/ToolChains/Cuda.cpp:431
- SmallString<256> Name(II.getFilename());
- llvm::sys::path::replace_extension(Name, "cubin");

- const char *CubinF =
- C.addTempFile(C.getArgs().MakeArgString(Name));
+ const char *CubinF = C.addTempFile(
+ C.getArgs().MakeArgString(getToolChain().getInputFilename(II)));

Considering that the function may also return an object file can you add an
assert here that getInputFileName(II) returns a cubin in this case?
================
Comment at: lib/Driver/ToolChains/Cuda.cpp:461
+std::string CudaToolChain::getInputFilename(const InputInfo &Input) const {
+ if (OK != Action::OFK_OpenMP || Input.getType() != types::TY_Object)
+ return ToolChain::getInputFilename(Input);

Can you put this info in a comment just before the if statement?
================
Comment at: test/Driver/openmp-offload-gpu.c:51
+// CHK-UNBUNDLING-PTXAS-CUBIN-NVLINK-DAG: clang-offload-bundler{{.*}}"
"-type=s" {{.*}}"-outputs={{.*}}[[PTX]]
+// CHK-UNBUNDLING-PTXAS-CUBIN-NVLINK: nvlink{{.*}}" {{.*}}"[[CUBIN]]"
----------------
This is kind of optional but since the name of the tool contains the word
"bundler" and you are performing an unbundling operation, could you also check
that the -unbundle flag is passed?
