[PATCH] D111529: Specify Clang vector builtins.

[Krzysztof Parzyszek via Phabricator via cfe-commits]

kparzysz added inline comments.


================
Comment at: clang/docs/LanguageExtensions.rst:553
+Each builtin returns a scalar equivalent to applying the specified
+operation(x, y) as horizontal recursive pairwise reduction to all vector
+elements. In each reduction step, ``operation(x, y)`` is applied to adjacent
----------------
It's really not clear what "horizontal recursive pairwise" means unless one has read the mailing list discussions.  Maybe you could spell it out, e.g. "recursive even-odd pairwise reduction" or something like that.
