================
Comment at: lib/Driver/ToolChains/Clang.cpp:4429
       Args.AddAllArgs(CmdArgs, options::OPT_fopenmp_cuda_blocks_per_sm_EQ);
+      Args.AddLastArg(CmdArgs, options::OPT_fopenmp_optimistic_collapse,
+                      options::OPT_fno_openmp_optimistic_collapse);
----------------
fno_openmp_optimistic_collapse is not a frontend option. better to check for
```
if (Args.hasFlag(options::OPT_fopenmp_optimistic_collapse,
                   options::OPT_fno_openmp_optimistic_collapse,
                   /*Default=*/false))
  CmdArgs.push_back("-fopenmp-optimistic-collapse");
```
here rather than in the frontend. In the frontend, you can just check for the presence of the fopenmp_optimistic_collapse flag
