The difference is there is no `ImplicitCastExpr` to `void*` in the AST: https://godbolt.org/z/9dcT8Tzs4 This does not change the behaviour for the first few arguments, but the last two arguments can no longer pass `nullptr` with non-zero bit patterns. This has differences at runtime if `nullptr` prvalues are passed to a variadic function: https://godbolt.org/z/19vovz8o6 https://github.com/llvm/llvm-project/pull/104704 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
