--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
/* { dg-do compile } */
/* { dg-options "-O3" } */
/* { dg-additional-options "-march=i686 -mtune=atom -msse2" { target ia32 } }
*/
void
foo (double *x, int *y)
{
int i;
for (i = 0; i < 8; i++)
x[i] -= y[i] * x[i + 1];
}
Started to ICE with r230310.
