What about the more simpler

  unsigned a, d;
  __asm__ volatile("rdtsc" : "=a" (a), "=d" (d));
  value= ((unsigned long long)a) | (((unsigned long long)d) << 32);

which should work for both x86 and x86_64 according to https://web.archive.org/web/20161215213659/http://www.cs.wm.edu/~kearns/001lab.d/rdtsc.html ?
