From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 4 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 4 of unsigned .SAT_SUB.
Form 4:
#define SAT_SUB_U_4(T) \
T sat_sub_u_4_##T (T x, T y) \
{ \
return x >= y ? x - y : 0; \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-13.c: New test.
* gcc.target/riscv/sat_u_sub-14.c: New test.

From: pan2.li @ 2024-06-14 2:13 UTC (permalink / raw)
To: gcc-patches; +Cc: juzhe.zhong, kito.cheng, jeffreyalaw, rdapp.gcc, Pan Li
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 5 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 5 of unsigned .SAT_SUB.
Form 5:
#define SAT_SUB_U_5(T) \
T sat_sub_u_5_##T (T x, T y) \
{ \
return x < y ? 0 : x - y; \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-17.c: New test.
* gcc.target/riscv/sat_u_sub-18.c: New test.
* gcc.target/riscv/sat_u_sub-19.c: New test.
* gcc.target/riscv/sat_u_sub-20.c: New test.
* gcc.target/riscv/sat_u_sub-run-17.c: New test.
* gcc.target/riscv/sat_u_sub-run-18.c: New test.
* gcc.target/riscv/sat_u_sub-run-19.c: New test.
* gcc.target/riscv/sat_u_sub-run-20.c: New test.

Subject: [PATCH v1 3/8] RISC-V: Add testcases for scalar unsigned SAT_SUB form 5
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 5 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 5 of unsigned .SAT_SUB.
Form 5:
#define SAT_SUB_U_5(T) \
T sat_sub_u_5_##T (T x, T y) \
{ \
return x < y ? 0 : x - y; \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-17.c: New test.
* gcc.target/riscv/sat_u_sub-18.c: New test.

Subject: [PATCH v1 4/8] RISC-V: Add testcases for scalar unsigned SAT_SUB form 6
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 6 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 6 of unsigned .SAT_SUB.
Form 6:
#define SAT_SUB_U_6(T) \
T sat_sub_u_6_##T (T x, T y) \
{ \
return x <= y ? 0 : x - y; \
}
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-21.c: New test.
* gcc.target/riscv/sat_u_sub-22.c: New test.
* gcc.target/riscv/sat_u_sub-23.c: New test.
* gcc.target/riscv/sat_u_sub-24.c: New test.
* gcc.target/riscv/sat_u_sub-run-21.c: New test.
* gcc.target/riscv/sat_u_sub-run-22.c: New test.
* gcc.target/riscv/sat_u_sub-run-23.c: New test.
* gcc.target/riscv/sat_u_sub-run-24.c: New test.

From: pan2.li @ 2024-06-14 2:13 UTC (permalink / raw)
To: gcc-patches; +Cc: juzhe.zhong, kito.cheng, jeffreyalaw, rdapp.gcc, Pan Li
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 7 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 7 of unsigned .SAT_SUB.
Form 7:
#define SAT_SUB_U_7(T) \
T sat_sub_u_7_##T (T x, T y) \
{ \
T ret; \
T overflow = __builtin_sub_overflow (x, y, &ret); \
return ret & (T)(overflow - 1); \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-25.c: New test.
* gcc.target/riscv/sat_u_sub-26.c: New test.
* gcc.target/riscv/sat_u_sub-27.c: New test.
* gcc.target/riscv/sat_u_sub-28.c: New test.
* gcc.target/riscv/sat_u_sub-run-25.c: New test.
* gcc.target/riscv/sat_u_sub-run-26.c: New test.
* gcc.target/riscv/sat_u_sub-run-27.c: New test.
* gcc.target/riscv/sat_u_sub-run-28.c: New test.

After the middle-end support the form 7 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 7 of unsigned .SAT_SUB.
Form 7:
#define SAT_SUB_U_7(T) \
T sat_sub_u_7_##T (T x, T y) \
{ \
T ret; \
T overflow = __builtin_sub_overflow (x, y, &ret); \
return ret & (T)(overflow - 1); \
}
Passed the rv64gcv fully regression test.

case to cover the form 8 of unsigned .SAT_SUB.
Form 8:

T overflow = __builtin_sub_overflow (x, y, &ret); \

}
Passed the rv64gcv fully regression test.

Subject: [PATCH v1 6/8] RISC-V: Add testcases for scalar unsigned SAT_SUB form 8
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 8 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 8 of unsigned .SAT_SUB.
Form 8:
#define SAT_SUB_U_8(T) \
T sat_sub_u_8_##T (T x, T y) \
{ \
T ret; \
T overflow = __builtin_sub_overflow (x, y, &ret); \
return ret & (T)-(!overflow); \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-29.c: New test.
* gcc.target/riscv/sat_u_sub-30.c: New test.
* gcc.target/riscv/sat_u_sub-31.c: New test.
* gcc.target/riscv/sat_u_sub-32.c: New test.
* gcc.target/riscv/sat_u_sub-run-29.c: New test.
* gcc.target/riscv/sat_u_sub-run-30.c: New test.
* gcc.target/riscv/sat_u_sub-run-31.c: New test.
* gcc.target/riscv/sat_u_sub-run-32.c: New test.

After the middle-end support the form 9 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 9 of unsigned .SAT_SUB.
Form 9:
#define SAT_SUB_U_9(T) \
T sat_sub_u_9_##T (T x, T y) \
{ \
T ret; \
T overflow = __builtin_sub_overflow (x, y, &ret); \
return overflow ? 0 : ret; \
}
Passed the rv64gcv fully regression test.

From: pan2.li @ 2024-06-14 2:13 UTC (permalink / raw)
To: gcc-patches; +Cc: juzhe.zhong, kito.cheng, jeffreyalaw, rdapp.gcc, Pan Li
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 10 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 10 of unsigned .SAT_SUB.
Form 10:
#define SAT_SUB_U_10(T) \
T sat_sub_u_10_##T (T x, T y) \
{ \
T ret; \
T overflow = __builtin_sub_overflow (x, y, &ret); \
return !overflow ? ret : 0; \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-37.c: New test.
* gcc.target/riscv/sat_u_sub-38.c: New test.
* gcc.target/riscv/sat_u_sub-39.c: New test.
* gcc.target/riscv/sat_u_sub-40.c: New test.
* gcc.target/riscv/sat_u_sub-run-37.c: New test.
* gcc.target/riscv/sat_u_sub-run-38.c: New test.
* gcc.target/riscv/sat_u_sub-run-39.c: New test.
* gcc.target/riscv/sat_u_sub-run-40.c: New test.

Subject: [PATCH v1 8/8] RISC-V: Add testcases for scalar unsigned SAT_SUB form 10
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 10 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 10 of unsigned .SAT_SUB.
Form 10:
#define SAT_SUB_U_10(T) \
T sat_sub_u_10_##T (T x, T y) \
{ \
T ret; \
T overflow = __builtin_sub_overflow (x, y, &ret); \
return !overflow ? ret : 0; \
}
Passed the rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for test.
* gcc.target/riscv/sat_u_sub-37.c: New test.
* gcc.target/riscv/sat_u_sub-38.c: New test.
* gcc.target/riscv/sat_u_sub-39.c: New test.
* gcc.target/riscv/sat_u_sub-40.c: New test.
* gcc.target/riscv/sat_u_sub-run-37.c: New test.
* gcc.target/riscv/sat_u_sub-run-38.c: New test.
* gcc.target/riscv/sat_u_sub-run-39.c: New test.
* gcc.target/riscv/sat_u_sub-run-40.c: New test.

Subject: [PATCH v1 1/8] RISC-V: Add testcases for scalar unsigned SAT_SUB form 3
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 3 of unsigned SAT_SUB and
the RISC-V backend implement the scalar .SAT_SUB, add more test
case to cover the form 3 of unsigned .SAT_SUB.
Form 3:
#define SAT_SUB_U_3(T) \
T sat_sub_u_3_##T (T x, T y) \
{ \
return x > y ? x - y : 0; \
}
Passed the rv64gcv fully regression test.
