--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
t = 3<=(x2|1|x3|x1-1U);
Doing the non-volatile sub:
t = 3 <= (x2 | 1 | 2 | (x1 - 1u))
...
t = 3 <= (x2 | 3 | (x1 - 1u))
or:
t = 3 <= 3 | x2 | (x1 - 1u)
Which is:
t = true, x1, x2.
Only if re-association happens with casts thrown in too which might be the
case of the regression.
