Sure - this goes back to my adding the "indirect" flag to support C++ non-trivial pass by value in C++, before we had all the more general expression support, etc. (hilariously, what was there before was even more awesome: we encoded the type of the parameter in the DWARF as T& instead of T... literally changing the signature of the function... )

Awesome, Bob just did the same thing for CodeView for NRVO in r312034, because we don't have DWOPderef. Oh, hey, right... Is this what MSVC does? That does seem unfortunate. They don't do NRVO in -O0 builds. -------------- next part -------------- An HTML attachment was scrubbed...
