RISC-V: Add testcases for form 2 of signed scalar SAT_ADD
This patch would like to add testcases of the signed scalar SAT_ADD
for form 2. Aka:
Form 2:
#define DEF_SAT_S_ADD_FMT_2(T, UT, MIN, MAX) \
T __attribute__((noinline)) \
sat_s_add_##T##_fmt_2 (T x, T y) \
{ \
T sum = (UT)x + (UT)y; \
if ((x ^ y) < 0 || (sum ^ x) >= 0) \
return sum; \
return x < 0 ? MIN : MAX; \
}
DEF_SAT_S_ADD_FMT_2 (int64_t, uint64_t, INT64_MIN, INT64_MAX)
The below test are passed for this patch.
* The rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add test helper macros.
* gcc.target/riscv/sat_s_add-5.c: New test.
* gcc.target/riscv/sat_s_add-6.c: New test.
* gcc.target/riscv/sat_s_add-7.c: New test.
* gcc.target/riscv/sat_s_add-8.c: New test.
* gcc.target/riscv/sat_s_add-run-5.c: New test.
* gcc.target/riscv/sat_s_add-run-6.c: New test.
* gcc.target/riscv/sat_s_add-run-7.c: New test.
* gcc.target/riscv/sat_s_add-run-8.c: New test.
