`_Alignas` on a field used to work properly before b9cf7f1066cc7ec11c6074d10b0f2ec9a3ae72d9, but that commit changed `alignas` handling improperly. The issue boils down to the fact that C++ treats `alignas` as an attribute and C treats `_Alignas` (and now `alignas` as of C23) as a type specifier rather than an attribute. We were originally leaning on the C++ implementation when the keyword was spelled `alignas` and we missed some changes to make that work in C, which is what this commit is addressing (by ensuring the attribute moves onto the declarator where it belongs and used to be found). https://github.com/llvm/llvm-project/pull/98642 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
