RISC-V: Add testcases for unsigned scalar quad and oct .SAT_TRUNC form 2
This patch would like to add test cases for the unsigned scalar quad and
oct .SAT_TRUNC form 2. Aka:
Form 2:
#define DEF_SAT_U_TRUC_FMT_2(NT, WT) \
NT __attribute__((noinline)) \
sat_u_truc_##WT##_to_##NT##_fmt_2 (WT x) \
{ \
WT max = (WT)(NT)-1; \
return x > max ? (NT) max : (NT)x; \
}
QUAD:
DEF_SAT_U_TRUC_FMT_2 (uint16_t, uint64_t)
DEF_SAT_U_TRUC_FMT_2 (uint8_t, uint32_t)
OCT:
DEF_SAT_U_TRUC_FMT_2 (uint8_t, uint64_t)
The below test is passed for this patch.
* The rv64gcv regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_u_trunc-10.c: New test.
* gcc.target/riscv/sat_u_trunc-11.c: New test.
* gcc.target/riscv/sat_u_trunc-12.c: New test.
* gcc.target/riscv/sat_u_trunc-run-10.c: New test.
* gcc.target/riscv/sat_u_trunc-run-11.c: New test.
* gcc.target/riscv/sat_u_trunc-run-12.c: New test.
