[PATCH] D115429: [Clang] Implement the rest of __builtin_elementwise_* functions.

[Jun Zhang via Phabricator via cfe-commits]

junaire added a comment.

> The RFC does not mention this builtin. It specifies `__builtin_elementwise_rint` and `__builtin_elementwise_round`. Is there a reason why this uses `roundeven` instead and should there be other rounding options provided at the same time?

Well, I think there may be a misunderstanding. I referenced: https://clang.llvm.org/docs/LanguageExtensions.html#vector-builtins
There is this builtin:

  T __builtin_elementwise_roundeven(T x)

But I just found in the RFC(https://lists.llvm.org/pipermail/cfe-dev/2021-September/068999.html), we have:

  • __builtin_elementwise_rint
  • __builtin_elementwise_round

It looks confusing, I would like to review the RFC again.
