C++ (Cpp) __lzcnt32 Examples

Example #1

File: lzcnt-4.c Project: 0day-ci/gcc

static void
lzcnt_test ()
{
  unsigned i;
  int src = 0xce7ace0;
  int res, res_ref;

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

    res_ref = calc_lzcnt_u32 (src);
    res = __lzcnt32 (src);

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