            Bug ID: 107929
           Summary: std::experimental::simd needs to be reimplemented with
                    GCC's vector extension
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: unlvsur at live dot com
  Target Milestone: ---

It is just too slow to compile by including immintrin.h headers. Using vector
extension is extremely easy to implement and more direct.
