I _guess_ we want a variant of this intrinsic which doesn't affect analyzation for devirtualization. Such an intrinsic should be sufficient for **C++23** `std::start_lifetime_as(_array)`. > * for now, it is non-constant, thus cannot be executed in constant evaluation; It seems intended that `std::start_lifetime_as(_array)` is not usable in constant evaluation, as the indeterminism of implicit object creation doesn't seem compatible with constant evaluation. https://github.com/llvm/llvm-project/pull/82776 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
