C++ (Cpp) __tzcnt_u32 Examples

Example #1

File: bmi-tzcnt-2.c Project: 0day-ci/gcc

static void
bmi_test ()
{
  unsigned i;
  int src = 0xfacec0ff;
  int res, res_ref;

  for (i=0; i<5; ++i) {
    src = i + src << i;

    res_ref = calc_tzcnt_u32 (src);
    res = __tzcnt_u32 (src);

    if (res != res_ref)
      abort();
  }
}

Example #2

unsigned int test__tzcnt_u32(unsigned int __X) {
  // CHECK-LABEL: test__tzcnt_u32
  // CHECK: icmp ne i32 %{{.*}}, 0
  // CHECK: i32 @llvm.cttz.i32(i32 %{{.*}}, i1 true)
  return __tzcnt_u32(__X);
}
