For RefPtr<T> GetFoo() { RefPtr<T> foo; // ... }
should we: 1. return foo and expect RVO to kick in to eliminate additional AddRef/Release 2. return foo.forget() 3. return Move(foo) Which one is preferred? ps: I find gcc is able to apply RVO even with "-O0". Not sure if it is also true for other compilers. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
