rjmccall added a comment. Hmm. The OVE-ing of the RHS of a property assignment is just there to make the original source structure clearer. Maybe the right solution here is to set a flag in the OVE that says that it's a unique semantic reference to its source expression, and then change IRGen to just recurse through OVEs with that flag set (and not pre-bind it).
You should make sure that we don't get this assertion with mandatory copy-elision and ?:, which does actually use its LHS multiple times semantically (and which cannot safely perform mandatory copy-elision on it). https://reviews.llvm.org/D39562 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
