Revision 1.10 2002-05-18 13:34:22 peter
* readded missing revisions
Revision 1.9 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 1.7 2002/04/20 21:37:07 carl
+ generic FPC_CHECKPOINTER
+ first parameter offset in stack now portable
* rename some constants
+ move some cpu stuff to other units
- remove unused constents
* fix stacksize for some targets
* fix generic size problems which depend now on EXTEND_SIZE constant
* removing frame pointer in routines is only available for : i386,m68k and vis targets
Revision 1.6 2002/04/07 13:41:50 carl
- moved type constant
Revision 1.5 2002/04/02 17:11:34 peter
* tlocation,treference update
* LOC_CONSTANT added for better constant handling
* secondadd splitted in multiple routines
* location_force_reg added for loading a location to a register
of a specified size
* secondassignment parses now first the right and then the left node
(this is compatible with Kylix). This saves a lot of push/pop especially
with string operations
* adapted some routines to use the new cg methods
