Csmith (lattest development version as of today) still manages to generate code that use int8 with following command
csmith --max-funcs 1 --no-checksum --no-safe-math --max-block-depth 2 --no-int8 --no-uint8 --no-longlong --no-math64
union U2 {
volatile int8_t * const volatile f0;
int32_t f1;
uint32_t f2;
};
/* --- GLOBAL VARIABLES --- */
static int8_t * volatile g_2 = (void*)0;/* VOLATILE GLOBAL g_2 */
static int8_t g_4 = (-8L);
