From: Pan Li <pan2...@intel.com>
Add run and tree-optimized check for unsigned scalar SAT_MUL from
uint128_t.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat/sat_arith.h: Add test helper macros.
* gcc.target/riscv/sat/sat_arith_data.h: Add test data for
run test.
* gcc.target/riscv/sat/sat_u_mul-1-u16-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-1-u32-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-1-u64-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-1-u8-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-1-u16-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-1-u32-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-1-u64-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-1-u8-from-u128.c: New test.
