			* Fixed registers that are allocated but not freed in several nodes
  * Tweak to register allocator to cause less spills
  * 8-bit registers now interfere with esi,edi and ebp
    Compiler can now compile rtl successfully when using new register
    allocator

|   Revision 1.27  2003-04-25 08:25:26  daniel
 | |
|     * Ifdefs around a lot of calls to cleartempgen
 | |
|     * Fixed registers that are allocated but not freed in several nodes
 | |
|     * Tweak to register allocator to cause less spills
 | |
|     * 8-bit registers now interfere with esi,edi and ebp
 | |
|       Compiler can now compile rtl successfully when using new register
 | |
|       allocator
 | |
| 
 | |
|   Revision 1.26  2003/04/24 22:29:57  florian
 | |
|     * fixed a lot of PowerPC related stuff
 | |
| 
 | |
|   Revision 1.25  2003/04/22 23:50:22  peter
 | |
|     * firstpass uses expectloc
 | |
|     * checks if there are differences between the expectloc and
 | |
|       location.loc from secondpass in EXTDEBUG
 | |
| 
 | |
|   Revision 1.24  2003/04/22 10:09:35  daniel
 | |
|     + Implemented the actual register allocator
 | |
|     + Scratch registers unavailable when new register allocator used
 | |
|     + maybe_save/maybe_restore unavailable when new register allocator used
 | |
| 
 | |
|   Revision 1.23  2003/04/06 21:11:23  olle
 | |
|     * changed newasmsymbol to newasmsymboldata for data symbols
 | |
| 
 | |
|   Revision 1.22  2003/03/28 19:16:56  peter
 | |
|     * generic constructor working for i386
 | |
|     * remove fixed self register
 | |
|     * esi added as address register for i386
 | |
| 
 | |
|   Revision 1.21  2003/02/19 22:00:14  daniel
 | |
|     * Code generator converted to new register notation
 | |
|     - Horribily outdated todo.txt removed
 | |
| 
 | |
|   Revision 1.20  2003/01/31 22:47:27  peter
 | |
|     * fix previous typeof change
 | |
| 
 | |
|   Revision 1.19  2003/01/30 21:46:57  peter
 | |
|     * self fixes for static methods (merged)
 | |
| 
 | |
|   Revision 1.18  2003/01/08 18:43:56  daniel
 | |
|    * Tregister changed into a record

| 
 | |
|   Revision 1.17  2002/11/25 17:43:18  peter
 | |
|     * splitted defbase in defutil,symutil,defcmp
 | |
|     * merged isconvertable and is_equal into compare_defs(_ext)
 | |
|     * made operator search faster by walking the list only once
 | |
| 
 | |
|   Revision 1.16  2002/10/05 12:43:25  carl
 | |
|     * fixes for Delphi 6 compilation

 | |
|   Revision 1.14  2002/09/17 18:54:02  jonas
 | |
|     * a_load_reg_reg() now has two size parameters: source and dest. This
 | |
|       allows some optimizations on architectures that don't encode the
 | |
|       register size in the register name.
 | |
| 
 | |
|   Revision 1.13  2002/08/13 18:01:52  carl

|       tasmlibrarydata that will hold the info of a .a file which
 | |
|       corresponds with a single module. Added librarydata to tmodule
 | |
|       to keep the library info stored for the module. In the future the
 | |
|       objectfiles will also be stored to the tasmlibrarydata class
 | |
|     * all getlabel/newasmsymbol and friends are moved to the new class

 | |
|     + added direct assembler reader for PowerPC
 | |
| 
 | |
|   Revision 1.4  2002/07/26 09:45:20  florian
