             Bug #: 52750
           Summary: 32xsigned char __builtin_shuffle
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: middle-end
        AssignedTo: ja...@gcc.gnu.org

typedef signed char V __attribute__((vector_size (32)));
V
f (V x)
{
  V m = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31};
  return __builtin_shuffle (x, m);
}

ICEs without -mavx2, because generic vector lowering is using a wrong type for
BIT_FIELD_REF positions.
