[PATCH] D49466: Initial implementation of -fmacro-prefix-map and -ffile-prefix-map

[Dan McGregor via Phabricator via cfe-commits]

dankm updated this revision to Diff 181151.
dankm added a comment.

Added unit tests for the prefix remapping.

Switched the sorting on the prefix map, so that <somepath>/sub gets remapped before <somepath> if both are specified.

I intend to do a more invasive change after this review to unify path prefix remapping.
