--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That looks like undefined behavior in the testcase. fn1 is K&R function with
int argument, like if it was:
void
fn1 (p)
int p;
{
f = 1 ^ e[f ^ (p & 1)];
}
but you are calling it with long long argument instead in fn2. If I change
it to void fn1 (p) long long p; { ... } or void fn1 (int p) { ... } or
change fn2 callers to cast the expressions to (int), it works fine.
