I wonder how valid the expression form of this is. The reason `sizeof` needs to take both is because C doesn't have `decltype`. I quite dislike builtins that take expressions because they aren't as obvious that they are unevaluated, despite being in a `function call` syntax location. https://github.com/llvm/llvm-project/pull/131515 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
