[PATCH] D33788: Return a canonical path from getClangResourcePath()

[Argyrios Kyrtzidis via Phabricator via cfe-commits]

akyrtzi added a comment.

Getting the real path is notoriously slow (at least it's horrible in OSX, not sure about linux). Since this is about dropping the '/../' part, could we do some simple canonicalization of removing the dots ? Not sure if there is an existing function that does that.
