RISC-V: Add testcases for vector truncate after .SAT_SUB
This patch would like to add the test cases of the vector truncate after
.SAT_SUB. Aka:
#define DEF_VEC_SAT_U_SUB_TRUNC_FMT_1(OUT_T, IN_T) \
void __attribute__((noinline)) \
vec_sat_u_sub_trunc_##OUT_T##_fmt_1 (OUT_T *out, IN_T *op_1, IN_T y, \
unsigned limit) \
{ \
unsigned i; \
for (i = 0; i < limit; i++) \
{ \
IN_T x = op_1[i]; \
out[i] = (OUT_T)(x >= y ? x - y : 0); \
} \
}
The below 3 cases are included.
DEF_VEC_SAT_U_SUB_TRUNC_FMT_1(uint8_t, uint16_t)
DEF_VEC_SAT_U_SUB_TRUNC_FMT_1(uint16_t, uint32_t)
DEF_VEC_SAT_U_SUB_TRUNC_FMT_1(uint32_t, uint64_t)
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/binop/vec_sat_arith.h: Add helper
test macros.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_binary_scalar.h: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_sub_trunc-1.c: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_sub_trunc-2.c: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_sub_trunc-3.c: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_sub_trunc-run-1.c: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_sub_trunc-run-2.c: New test.
* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_sub_trunc-run-3.c: New test.
