  $Log$
  Revision 1.2  2002-08-12 15:08:44  carl
    + stab register indexes for powerpc (moved from gdb to cpubase)
    + tprocessor enumeration moved to cpuinfo
    + linker in target_info is now a class
    * many many updates for m68k (will soon start to compile)
    - removed some ifdef or correct them for correct cpu

  Revision 1.1  2002/08/11 08:06:09  carl
    + try to commit this ** file again

  Revision 1.7  2002/05/18 13:34:26  peter
    * readded missing revisions

  Revision 1.6  2002/05/16 19:46:53  carl
  + defines.inc -> fpcdefs.inc to avoid conflicts if compiling by hand
  + try to fix temp allocation (still in ifdef)
  + generic constructor calls
  + start of tassembler / tmodulebase class cleanup

  Revision 1.4  2002/05/13 19:52:46  peter
    * a ppcppc can be build again

  Revision 1.3  2002/04/07 13:43:11  carl
  - moved type constant
