I don't think this is very expensive given that Explorer often makes zillions of such calls, but I'm open to other suggestions. I know that you can't use a library that's newer than the compiler (because it may use new language features), but I don't know if that applies in the other direction or how we would safely and reliably map directory names to library versions and therefore to compiler versions. http://reviews.llvm.org/D20136 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
