--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Actually I think we should do:
(simplify
(mult:c truth_valuep@0 @1)
(and (neg @0) @1))
Instead. What do you think?
This will catch things like:
unsigned long foo (long a, unsigned long b)
{
unsigned long t = a & 1;
return t * b;
}
---- CUT ---
We can put a ! after neg if we want it to be optimized out even.
