  $Log$
  Revision 1.6  2002-05-16 19:46:50  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  2001/07/01 20:16:20  peter
    * alignmentinfo record added
    * -Oa argument supports more alignment settings that can be specified
      per type: PROC,LOOP,VARMIN,VARMAX,CONSTMIN,CONSTMAX,RECORDMIN
      RECORDMAX,LOCALMIN,LOCALMAX. It is possible to set the mimimum
      required alignment and the maximum usefull alignment. The final
      alignment will be choosen per variable size dependent on these
      settings

  Revision 1.3  2001/05/12 12:11:31  peter
    * simplify_ppu is now the default, a recompile of the compiler now
      only compiles pp.pas

  Revision 1.2  2000/12/23 19:46:49  peter
    * object to class conversion
    * more verbosity for -vt and -vd
    * -i options can be put after eachother so the Makefiles only need
      to call fpc once for all info (will be twice as the first one will
      be to check the version if fpc supports multiple info)

  Revision 1.1  2000/11/30 22:42:50  florian
  * renamed

  Revision 1.1  2000/11/30 22:21:56  florian
    * moved to i386

  Revision 1.6  2000/10/24 10:40:53  jonas
    + register renaming ("fixes" bug1088)
    * changed command line options meanings for optimizer:
        O2 now means peepholopts, CSE and register renaming in 1 pass
        O3 is the same, but repeated until no further optimizations are
          possible or until 5 passes have been done (to avoid endless loops)
    * changed aopt386 so it does this looping
    * added some procedures from csopt386 to the interface because they're
      used by rropt386 as well
    * some changes to csopt386 and daopt386 so that newly added instructions
      by the CSE get optimizer info (they were simply skipped previously),
      this fixes some bugs

  Revision 1.5  2000/09/24 15:06:20  peter
    * use defines.inc

  Revision 1.4  2000/08/27 16:11:51  peter
    * moved some util functions from globals,cobjects to cutils
    * splitted files into finput,fmodule

  Revision 1.3  2000/07/27 13:03:36  jonas
    * release alignopts

  Revision 1.2  2000/07/13 11:32:44  michael
  + removed logs
