[libcxx-commits] [PATCH] D97283: [libcxx][type_traits] is_unsigned is false for enum types

[Mark de Wever via Phabricator via libcxx-commits]

Mordante added a comment.

It's a clang bug: clang/docs/LanguageExtensions.rst:1024

  * ``__is_unsigned`` (C++, Embarcadero)
    Note that this currently returns true for enumeration types if the underlying
    type is unsigned, in violation of the requirements for ``std::is_unsigned``.
    This behavior is likely to change in a future version of Clang.

@zoecarver fixed the signed part in D67897 <https://reviews.llvm.org/D67897>

I want to look at the Clang site unless somebody beats me to it.
