That's correct. We detect and diagnose the mismatch through `mergeParamDeclAttributes`, which gets called by `MergeCompatabileFunctionDecls`, so we need to allow the merge call to proceed even for cases here that might be invalid. Alternatively we could move that diagnostic out somewhere earlier. https://github.com/llvm/llvm-project/pull/101083 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
