RISC-V: Add testcases for form 4 of vector signed SAT_SUB
Form 4:
#define DEF_VEC_SAT_S_SUB_FMT_4(T, UT, MIN, MAX) \
void __attribute__((noinline)) \
vec_sat_s_sub_##T##_fmt_4 (T *out, T *op_1, T *op_2, unsigned limit) \
{ \
unsigned i; \
for (i = 0; i < limit; i++) \
{ \
T x = op_1[i]; \
T y = op_2[i]; \
T minus; \
bool overflow = __builtin_sub_overflow (x, y, &minus); \
out[i] = !overflow ? minus : x < 0 ? MIN : MAX; \
} \
}
The below test are passed for this patch.
* The rv64gcv fully regression test.
It is test only patch and obvious up to a point, will commit it
directly if no comments in next 48H.
