  The patch was already committed when I wrote my mail. The patch solved
  a PR which wasn't mentioned in the posted patch.
  You suggested to add a REG_ALLOC_ORDER define. I now compared the
  generated code from a cc1 with REG_ALLOC_ORDER defined and one without.
  I think not defining REG_ALLOC_ORDER is better since with it defined
  GCC puts constants between 1..127 into a[01] even if it would be better
  to use another data register. The with REG_ALLOC_ORDER prefered approach
  might be better for small functions that only use scatch registers. IHMO,
  for complex functions the old behaviour was better.
