commit r15-4179-g8b407d5c6940a65d78a544f9c66850e619638171
Author: Pan Li <pan2...@intel.com>

RISC-V: Add testcases for form 1 of scalar signed SAT_TRUNC
Form 1:
#define DEF_SAT_S_TRUNC_FMT_1(WT, NT, NT_MIN, NT_MAX) \
NT __attribute__((noinline)) \
sat_s_trunc_##WT##_to_##NT##_fmt_1 (WT x) \
{ \
NT trunc = (NT)x; \
return (WT)NT_MIN <= x && x <= (WT)NT_MAX \
? trunc \
: x < 0 ? NT_MIN : NT_MAX; \
}
The below test are passed for this patch.
* The rv64gcv fully regression test.
It is test only patch and obvious up to a point, will commit it
directly if no comments in next 48H.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add test helper macros.
* gcc.target/riscv/sat_arith_data.h: Add test data for SAT_TRUNC.
* gcc.target/riscv/sat_s_trunc-1-i16-to-i8.c: New test.
* gcc.target/riscv/sat_s_trunc-1-i32-to-i16.c: New test.
* gcc.target/riscv/sat_s_trunc-1-i32-to-i8.c: New test.
* gcc.target/riscv/sat_s_trunc-1-i64-to-i16.c: New test.
* gcc.target/riscv/sat_s_trunc-1-i64-to-i32.c: New test.
* gcc.target/riscv/sat_s_trunc-1-i64-to-i8.c: New test.
* gcc.target/riscv/sat_s_trunc-run-1-i16-to-i8.c: New test.
* gcc.target/riscv/sat_s_trunc-run-1-i32-to-i16.c: New test.
* gcc.target/riscv/sat_s_trunc-run-1-i32-to-i8.c: New test.
* gcc.target/riscv/sat_s_trunc-run-1-i64-to-i16.c: New test.
* gcc.target/riscv/sat_s_trunc-run-1-i64-to-i32.c: New test.
* gcc.target/riscv/sat_s_trunc-run-1-i64-to-i8.c: New test.
