--- Comment #1 from Peter Bergner  ---
This is a test case bug.  The problem is the following code:

#if __ORDER_LITTLE_ENDIAN__
#define ELE 2
#else
#define ELE 1
#endif

vector float
foo (vector float v1, vector float v2)
{
  return vec_insert (vec_extract (v2, ELE), v1, 0);
}

The bug is that __ORDER_LITTLE_ENDIAN__ is always defined, so we pass the wrong
ELE value to vec_extract() call on big endian.  We should be testing
__LITTLE_ENDIAN__ instead.  Changing that fixes the failure.
