Thanks for pointing that out. I'll look into moving the test there

+    ArgList.push_back(Saver.save(Twine{"--reproduce="} + TmpName).data());
+    NewLLDInvocation.replaceArguments(std::move(ArgList));

Ah yeah good catch. Unfortunately this wasn't caught upstream because I quickly had to change to explicit target because *-ps4 target doesn't support `-fuse-ld` and there didn't already exist a PS4 lit feature that I could mark as unsupported. This was actually why you saw test failures on non linux platforms.

I'll make a new review that correctly uses `/reproduce:`. Thanks again
