LGTM juzhe.zhong@rivai.ai From: pan2.li Date: 2024-10-08 09:21 To: gcc-patches CC: richard.guenther; Tamar.Christina; juzhe.zhong; kito.cheng; jeffreyalaw; rdapp.gcc; Pan Li Subject: [PATCH v1 2/3] RISC-V: Add testcases for form 3 of scalar signed SAT_SUB From: Pan Li <pan2.li@intel.com> Form 3: #define DEF_SAT_S_SUB_FMT_3(T, UT, MIN, MAX) \ T __attribute__((noinline)) \ sat_s_sub_##T##_fmt_3 (T x, T y) \ { \ T minus; \ bool overflow = __builtin_sub_overflow (x, y, &minus); \ return overflow ? x < 0 ? MIN : MAX : minus; \ } 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_s_sub-3-i16.c: New test. * gcc.target/riscv/sat_s_sub-3-i32.c: New test. * gcc.target/riscv/sat_s_sub-3-i64.c: New test. * gcc.target/riscv/sat_s_sub-3-i8.c: New test. * gcc.target/riscv/sat_s_sub-run-3-i16.c: New test. * gcc.target/riscv/sat_s_sub-run-3-i32.c: New test. * gcc.target/riscv/sat_s_sub-run-3-i64.c: New test. * gcc.target/riscv/sat_s_sub-run-3-i8.c: New test.
