So empty structs in C are ignored, empty structs in C++ are treated as non-empty. The "C++ struct containing an empty array" is sort of an edge case, since it's not actually legal C++, but the spec says the distinguishing factor is whether we're in C++ mode. And gcc seems to do that, so let's do the same thing. So instead of checking for `Size == 0`, check for `LangOpts.CPlusPlus`. Also, please add a release note for this. https://github.com/llvm/llvm-project/pull/97315 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
