As to single-element struct, I'm refering to all the various special cases the code checks for. They should have tests that verify the intended behaviour. (And those tests should also be verified against the actual behavior of the legacy compilers.) In particular, does it count as single-element struct if: - we have any padding - we have a single element that is itself a single-element struct - we have a single element that is a single-element array - we have an element that is a bitfield of size zero (named or unnamed) - we have an element that is a bitfield of nonzero size - we have an element that is an empty struct - we have an element that is an empty array - it's a C++ class that has a C++20 empty data member (NoUniqueAddressAttr) - it's a C++ class that has an empty base class - it's a C++ class that has a non-empty base class https://github.com/llvm/llvm-project/pull/91384 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
