[PATCH] D100755: [llvm-rc] [3/4] Run clang to preprocess input files

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

Purely FYI: the `--` in the test isn't needed just on macOS but also on Linux if your checkout is eg under /usr: http://45.33.8.238/linux/44652/step_7.txt

(clang-cl has some nice diag if the /U flag is an existing file, since that happens fairly often. Maybe llvm-rc could have a nicer diag in that case too and suggest `--`)
