------- Additional Comments From steven at gcc dot gnu dot org 2004-08-12 07:41 -------
Mainline (3.5.0-to-be) claims the following:
t.c:1: warning: specifying vector types with __attribute__ ((mode)) is
deprecated
t.c:1: warning: use __attribute__ ((vector_size)) instead
Tweaking the test case accordingly makes the failure go away:
typedef int __m64 __attribute__ ((vector_size (2)));
int foo()
{
return (long long)(__m64)(0ll);
}
t.c: In function `foo':
t.c:5: error: can't convert between vector values of different size
I don't know if the new error makes sense.
