           Summary: incorrect _mm256_insert_epi{32,64} implementations
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: kr...@kde.org


see avxintrin.h:
_mm256_insert_epi32 and _mm256_insert_epi64 use _mm_insert_epi16 internally

if __OPTIMIZE__ is not defined they use _mm_insert_epi32/64 internally - as I
would have expected.

I also checked 4.5 and 4.4, and it seems the bug was not noticed in any branch
yet.
