--- Comment #1 from Peter Bergner <bergner at gcc dot gnu.org> ---
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.
