  31 /* ACLE standardises a set of pre-defines that describe the ARM architecture.
  32    These were mostly implemented in GCC around GCC-4.8; older versions
  33    have no, or only partial support.  To provide a level of backwards
  34    compatibility we try to work out what the definitions should be, given
  35    the older pre-defines that GCC did produce.  This isn't complete, but
  36    it should be enough for use by routines that depend on this header.  */
