            Bug ID: 52444
           Summary: [Clang] Implement missing elementwise & reduction
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C

Clang recently specified a set of builtins for elementwise operations and
reductions on vectors:


At the moment, the following builtins are implemented:

* _builtin_elementwise_abs https://reviews.llvm.org/rG01870d51b848
* _builtin_elementwise_max, _builtin_elementwise_min
* _builtin_reduce_max, _builtin_reduce_min

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
