/* { dg-do compile } */
/* { dg-options "-O2 -ffast-math -ftree-vectorize " } */
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Any particular reason why it should be in gcc.dg/torture, not in
gcc.dg/vect? -O2 here is overridden by -Ox.

/* { dg-additional-options "-mavx" { target { i?86-*-* x86_64-*-* } } } */
