            Bug ID: 16581
           Summary: avx2intrin.h should declare
                    _mm256_broadcastsi128_si256, not
           Product: clang
           Version: 3.3
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Headers
          Assignee: unassignedclangbugs at nondot.org

Intel's ISA document (and gcc's headers) define the intrinsic for
"vbroadcasti128" as "__m256i _mm256_broadcastsi128_si256(__m128i a)". It would
be nice if clang did the same.
