[PATCH] D86339: Enable constexpr on BITREVERSE builtin intrinsics (PR47249)

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

Can you also add documentation to LanguageExtensions.rst? Thanks!



================
Comment at: clang/docs/ReleaseNotes.rst:61
+  ``__builtin_bitreverse32`` and ``__builtin_bitreverse64`` may now be used
+  within constexpr expressions.
 
----------------
There's no such thing as a "constexpr expression". The right term is "constant expressions".
