commit 13eae3ea598541647de32a3a81b6188403990565
Author: Pan Li <pan2...@intel.com>
Date: Tue Jun 18 16:22:59 2024 +0800
RISC-V: Add testcases for unsigned .SAT_SUB scalar form 12
After the middle-end support the form 12 of unsigned SAT_SUB and
the RISC-V backend implement the SAT_SUB for vector mode, add
more test case to cover the form 12.
Form 12:
#define DEF_SAT_U_SUB_FMT_12(T) \
T __attribute__((noinline)) \
sat_u_sub_##T##_fmt_12 (T x, T y) \
{ \
T ret; \
bool overflow = __builtin_sub_overflow (x, y, &ret); \
return !overflow ? ret : 0; \
}
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-45.c: New test.
