Revision 1.4 2002-12-14 15:02:03 carl
|
|
* maxoperands -> max_operands (for portability in rautils.pas)
|
|
* fix some range-check errors with loadconst
|
|
+ add ncgadd unit to m68k
|
|
* some bugfix of a_param_reg with LOC_CREFERENCE
|
|
|
|
Revision 1.3 2002/09/17 18:26:02 jonas
|
|
- removed taicpu.destroy, its job is already handled by
|
|
taicpu_abstract.destroy() and this caused heap corruption
|
|
|
|
Revision 1.2 2002/07/26 11:19:57 jonas
|
|
* fixed range errors
|
|
|
|
Revision 1.1 2002/07/07 09:44:31 florian
|
|
* powerpc target fixed, very simple units can be compiled
|
|
|
|
Revision 1.8 2002/05/18 13:34:26 peter
|
|
* readded missing revisions
|
|
|
|
Revision 1.7 2002/05/16 19:46:53 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 2002/05/13 19:52:46 peter
|
|
* a ppcppc can be build again
