  Revision 1.1  2003-04-29 11:53:38  mazen
  + This file is used to define all cpu registers physically available

  Revision 1.3  2003/01/20 22:21:36  mazen
  * many stuff related to RTL fixed

  Revision 1.2  2002/10/02 22:20:28  mazen
  + out registers allocator for the first 6 scalar parameters which must be passed into %o0..%o5
