Yes, that definitely makes sense and is a lot nicer than having these two options, which I found quite ugly as well. I will fix that and upload a new patch set. ================ Comment at: test/Driver/cl-options.c:203 - -// RUN: %clang_cl /EP /P /showIncludes -### -- %s 2>&1 | FileCheck -check-prefix=showIncludes_E_And_P %s -// showIncludes_E_And_P-NOT: warning: argument unused during compilation: '--show-includes' ---------------- erichkeane wrote: > I'm perhaps missing something here... why did "/EP /P /showIncludes" > previously NOT warn? /P will preprocess to a file, so it was compatible with /showIncludes, which was printed to stdout. With this change all preprocessor options are now possible to use in combination with /showIncludes, since its output will be written to stderr, like cl.exe does. I was actually not sure if I shall keep these tests at all after my change or just invert them, like I ended up doing here. There is probably a better way to actually test that /showIncludes output will end up on stderr, but with my limited experience I didn't figure that out yet. Let me know if you have any ideas how to improve these tests.
