From: Pan Li <pan2...@intel.com>
This patch would like to add test cases for the unsigned scalar
.SAT_TRUNC form 3. Aka:
Form 3:
#define DEF_SAT_U_TRUC_FMT_3(NT, WT) \
NT __attribute__((noinline)) \
sat_u_truc_##WT##_to_##NT##_fmt_3 (WT x) \
{ \
WT max = (WT)(NT)-1; \
return x <= max ? (NT)x : (NT) max; \
}
DEF_SAT_U_TRUC_FMT_3 (uint32_t, uint64_t)
The below test is passed for this patch.
* The rv64gcv regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add test helper macros.
* gcc.target/riscv/sat_u_trunc-13.c: New test.
* gcc.target/riscv/sat_u_trunc-14.c: New test.
* gcc.target/riscv/sat_u_trunc-15.c: New test.
* gcc.target/riscv/sat_u_trunc-run-13.c: New test.
* gcc.target/riscv/sat_u_trunc-run-14.c: New test.
* gcc.target/riscv/sat_u_trunc-run-15.c: New test.
