I guess if it is supposed to be ill-formed, we can permit it (except in SFINAE?), right? The intent here is mostly just for 'cleanup' as we see it. ================ Comment at: clang/include/clang/Basic/DiagnosticSemaKinds.td:6985 +def err_typecheck_indirection_through_void_pointer_cpp + : Error<"ISO C++ does not allow indirection on operand of type %0">; def warn_indirection_through_null : Warning< ---------------- rsmith wrote: > We normally only use this "ISO C++ does not allow" phrasing for extensions > (with the implication being that ISO C++ doesn't allow it, but Clang does). > Can you rephrase the diagnostic too, to remove those unnecessary words? I definitely can. Though, I wonder if we can just use the err_typecheck_indirection_requires_pointer above instead and remove this diagnostic? We might need to change that to `indirection requires non-void pointer operand (%0 invalid)`. WDYT?
