<pre>Clang recently specified a set of builtins for elementwise operations and
reductions on vectors:
<a href="https://clang.llvm.org/docs/LanguageExtensions.html#vector-builtins">https://clang.llvm.org/docs/LanguageExtensions.html#vector-builtins</a>
At the moment, the following builtins are implemented:
* _builtin_elementwise_abs <a href="https://reviews.llvm.org/rG01870d51b848">https://reviews.llvm.org/rG01870d51b848</a>
* _builtin_elementwise_max, _builtin_elementwise_min
<a href="https://reviews.llvm.org/rG1ef25d28c19e">https://reviews.llvm.org/rG1ef25d28c19e</a>
* _builtin_reduce_max, _builtin_reduce_min
<a href="https://reviews.llvm.org/rG7999355106fb">https://reviews.llvm.org/rG7999355106fb</a>
The patches above can serve as blueprint for adding other builtin.
I am more than happy to help with reviews and new contributors, if anybody is
interested.</pre>
