  $Log$
  Revision 1.6  2003-01-05 13:36:54  florian
    * x86-64 compiles
    + very basic support for float128 type (x86-64 only)

  Revision 1.5  2002/09/07 15:25:15  peter
    * old logs removed and tabs fixed

  Revision 1.4  2002/08/12 15:08:45  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 1.3  2002/08/10 14:53:38  carl
    + moved target_cpu_string to cpuinfo
    * renamed asmmode enum.
    * assembler reader has now less ifdef's
    * move from nppcmem.pas -> ncgmem.pas vec. node.

  Revision 1.2  2002/07/25 22:55:34  florian
    * several fixes, small test units can be compiled

  Revision 1.1  2002/07/24 22:38:15  florian
    + initial release of x86-64 target code
