commit 1a6d2ed7fbd20bfa3079da4700eb591f2abaa395
Author: Pan Li <pan2...@intel.com>
Date: Mon Jun 3 10:43:10 2024 +0800
RISC-V: Add testcases for scalar unsigned SAT_ADD form 5
After the middle-end support the form 5 of unsigned SAT_ADD and
the RISC-V backend implement the scalar .SAT_ADD, add more test
case to cover the form 5 of unsigned .SAT_ADD.
Form 5:
#define SAT_ADD_U_5(T) \
T sat_add_u_5_##T(T x, T y) \
{ \
return (T)(x + y) < x ? -1 : (x + y); \
}
Passed the riscv fully regression tests.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add test macro for form 5.
* gcc.target/riscv/sat_u_add-21.c: New test.
* gcc.target/riscv/sat_u_add-22.c: New test.
* gcc.target/riscv/sat_u_add-23.c: New test.
* gcc.target/riscv/sat_u_add-24.c: New test.
* gcc.target/riscv/sat_u_add-run-21.c: New test.
* gcc.target/riscv/sat_u_add-run-22.c: New test.
* gcc.target/riscv/sat_u_add-run-23.c: New test.
* gcc.target/riscv/sat_u_add-run-24.c: New test.
