--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase which shows the issue on other targets (aarch64) too:
#include <stdbool.h>
#include <stdint.h>

extern bool z, c;

uint32_t f(uint32_t dest, uint32_t src)
{
    uint32_t res = dest - src;
    z = !res;
    c = src > dest;
    return res;
}
