            Bug ID: 36615
           Summary: _mm512_i32extgather_epi32 not implemented
           Product: clang
           Version: 4.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

All versions of extgather (at least _mm512_i32extgather_epi32 /
_mm512_i32extgather_ps) seem to be not implemented (or at least I did not find
them). I use Clang 4, but I did not manage to find them in Clang 5 and Trunk
either.
