- The cwg2563 issue is fixed by delaying GRO initialization only when the types mismatch between GRO and function return. - When the types match directly initialize, which indirectly enables RVO to kick in, partially restores behavior introduced in https://reviews.llvm.org/D117087. - Add entry to release notes. Background: https://github.com/llvm/llvm-project/issues/56532 https://cplusplus.github.io/CWG/issues/2563.html https://github.com/cplusplus/papers/issues/1414 Differential Revision: https://reviews.llvm.org/D145641
