From: Pan Li <[email protected]>
The form 5 of unsigned scalar SAT_MUL is covered in middle-expand
alreay, add test case here to cover form 5.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat/sat_arith.h: Add test helper macros.
* gcc.target/riscv/sat/sat_u_mul-6-u16-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-6-u32-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-6-u64-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-6-u8-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-6-u16-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-6-u32-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-6-u64-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-run-6-u8-from-u128.c: New test.
