Hrm, might not be as trivial as I was hoping (I thought we had a way to go from a `SourceLocation` back to a `Token`, but I'm not seeing one off-hand). Regardless, I worry about the expense of going all the way back to the source for this. @alexfh -- should this functionality be a part of a more general "we've made a fixit, now make it not look ugly?" pass? At least then, if we go back to the source, we can do it in a more controlled manner and hopefully get some performance back from that. https://reviews.llvm.org/D25406 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
