[PATCH] D90646: [clang] Add warning when `-include-pch` is passed multiple times

[Dave Lee via Phabricator via cfe-commits]

kastiglione added a comment.

Is there any reason that `-include-pch` shouldn't follow the precedent of `-include`, which can be used multiple times? If not, then the end goal should be to support multiple uses, but in the mean time a warning is helpful.
