From: Pan Li <pan2...@intel.com>
This patch would like to add test cases for the unsigned scalar quad and
oct .SAT_TRUNC form 4. Aka:
Form 4:
#define DEF_SAT_U_TRUNC_FMT_4(NT, WT) \
NT __attribute__((noinline)) \
sat_u_trunc_##WT##_to_##NT##_fmt_4 (WT x) \
{ \
bool not_overflow = x <= (WT)(NT)(-1); \
return ((NT)x) | (NT)((NT)not_overflow - 1); \
}
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-19.c: New test.
* gcc.target/riscv/sat_u_trunc-20.c: New test.
* gcc.target/riscv/sat_u_trunc-21.c: New test.
* gcc.target/riscv/sat_u_trunc-22.c: New test.
* gcc.target/riscv/sat_u_trunc-23.c: New test.
* gcc.target/riscv/sat_u_trunc-24.c: New test.
* gcc.target/riscv/sat_u_trunc-run-19.c: New test.
* gcc.target/riscv/sat_u_trunc-run-20.c: New test.
* gcc.target/riscv/sat_u_trunc-run-21.c: New test.
* gcc.target/riscv/sat_u_trunc-run-22.c: New test.
* gcc.target/riscv/sat_u_trunc-run-23.c: New test.
* gcc.target/riscv/sat_u_trunc-run-24.c: New test.
