| Series | [v1,1/8] RISC-V: Add testcases for scalar unsigned SAT_SUB form 3 | expand |
LGTM juzhe.zhong@rivai.ai From: pan2.li Date: 2024-06-14 10:13 To: gcc-patches CC: juzhe.zhong; kito.cheng; jeffreyalaw; rdapp.gcc; Pan Li 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.
