--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This:
expr->oper == GNM_EXPR_OP_FUNCALL &&
expr->func.argc == 1
is being combined into:
D.2319_2 = BIT_FIELD_REF <*expr_1, 64, 0>;
D.2320_3 = D.2319_2 & 18446744069414584575;
D.2320_3 == 4294967297
Which is correct and I think is valid.
Valgrind does not realize the part of expr will not match part of the
and/equals so it complains. Basically a bug in valgrind for not tracking
uninitialized bits correctly.
The solution to asan message was provided in comment #4.
