When you say regressions, I assume you mean size/performance, not correctness, right? If so, that's to be expected, as the previous tree-nrv implementation was being overly permissive, and the new implementation is conservatively pessimistic, as the comments indicate. If I have introduced anything incorrect, please let me know and I'd be glad to take a look. Thanks! -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32285
