  $Log$
  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
