--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

Reduced/more self-contained testcase:
void h(int result) __attribute__((noipa));
void h(int result)
{
    if (result)
        __builtin_exit(0);
}
void n(const char *value_1) __attribute__((noipa));
void n(const char *value_1)
{
    h(value_1 == 0);

    int result = !__builtin_strcmp(value_1, "value 1");
    __builtin_exit (!result);
}
int main()
{
    n(0);
}
