--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. x86 doesn't have integer abs patterns it seems and we end up using
expand_abs_nojump()s
/* If this machine has expensive jumps, we can do integer absolute
value of X as (((signed) x >> (W-1)) ^ x) - ((signed) x >> (W-1)),
where W is the width of MODE. */
