Yes, something like that. Maybe it could look like `-f__file__-expansion=basename` (to make __FILE__ expand to just the basename, what you want), `-f__file__-expansion=relative-to:/a/b/c` to make it relative to a given path. http://reviews.llvm.org/D17741 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
