--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
typedef double __attribute__ ((vector_size (16))) vec;
register vec a asm("xmm12"), b asm("xmm13"), c asm("xmm14");

void
test (void)
{
  for (int i = 0; i < 4; i++)
    c[i] = a[i] < b[i] ? 0.1 : 0.2;
}

ICEs with -O2 -mavx -ffixed-xmm{12,13,14} -std=gnu99 starting with
r0-104000-g30cd1c5d04c18770e8688d7199c20c2d528df1cd
when the vector indexing support has been added.
