--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
One way of fixing this is:
/* Transform (a * { 0 or 1 }) !=/== 0 into (a & { 0 or 1 }) !=/== 0. */
(for cmp (ne eq)
(simplify
(cmp (mult:cs @0 zero_one_valued_p@1) integer_zerop@2)
(cmp (bit_and @0 @1) @2)))
That is (a*zero_one_valued_p)!=0 transform it into (a & zero_one_valued_p) != 0
if the multiply was single use.
That is how I am going to fix this.
