This implements the rule intended by the standard (see LWG 2358) and the rule intended by the Itanium C++ ABI (see https://github.com/itanium-cxx-abi/cxx-abi/pull/51), and makes Clang match the behavior of GCC, ICC, and MSVC. A pedantic reading of both the standard and the ABI indicate that Clang is currently technically correct, but that's not worth much when it's clear that the wording is wrong in both those places. This is an ABI break for classes that derive from a class that is empty other than one or more unnamed non-zero-length bit-fields. Such cases are expected to be rare, but -fclang-abi-compat=6 restores the old behavior just in case. Differential Revision: https://reviews.llvm.org/D45174 llvm-svn: 331620 |
