RISC-V: Add testcases for form 2 of vector signed SAT_SUB
Form 2:
#define DEF_VEC_SAT_S_SUB_FMT_2(T, UT, MIN, MAX) \
void __attribute__((noinline)) \
vec_sat_s_sub_##T##_fmt_2 (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 = (UT)x - (UT)y; \
out[i] = (x ^ y) >= 0 || (minus ^ x) >= 0 \
? minus : x < 0 ? MIN : MAX; \
} \
}
DEF_VEC_SAT_S_SUB_FMT_2(int8_t, uint8_t, INT8_MIN, INT8_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.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/vec_sat_arith.h: Add test helper macros.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_s_sub-2-i16.c: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_s_sub-2-i32.c: New test.
