Subject: [PATCH v1 1/2] RISC-V: Add testcases for unsigned .SAT_SUB scalar form 11
Date: Tue, 18 Jun 2024 16:25:37 +0800 [thread overview]
Message-ID: <20240618082538.1744444-1-pan2.li@intel.com> (raw)
From: Pan Li <pan2.li@intel.com>
After the middle-end support the form 11 of unsigned SAT_SUB and
the RISC-V backend implement the SAT_SUB for vector mode, add
more test case to cover the form 11.
Form 11:
#define DEF_SAT_U_SUB_FMT_11(T) \
T __attribute__((noinline)) \
sat_u_sub_##T##_fmt_11 (T x, T y) \
{ \
T ret; \
bool overflow = __builtin_sub_overflow (x, y, &ret); \
return overflow ? 0 : ret; \
}
Passed the rv64gcv regression tests.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper
macro for testing.
* gcc.target/riscv/sat_u_sub-41.c: New test.
* gcc.target/riscv/sat_u_sub-42.c: New test.
* gcc.target/riscv/sat_u_sub-43.c: New test.
* gcc.target/riscv/sat_u_sub-44.c: New test.
* gcc.target/riscv/sat_u_sub-run-41.c: New test.
* gcc.target/riscv/sat_u_sub-run-42.c: New test.
* gcc.target/riscv/sat_u_sub-run-43.c: New test.
* gcc.target/riscv/sat_u_sub-run-44.c: New test.
