I think this isn't an unreasonable thing to want, but I think it's beneficial to be consistent with our existing API. So if we offer a generic thing for ldg, it would be nice to have one for atomics above, which are basically the same. So I told Art I'd prefer to add it to our list. http://reviews.llvm.org/D19990 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
