[PATCH] D114425: [clang] Add __builtin_bswap128

[Craig Topper via Phabricator via cfe-commits]

craig.topper added a comment.

What does the builtin due if __int128 isn't supported? Even though the type isn't legal the builtin can still be called with a narrower type that would be implicitly converted. Does that work correctly?
