|   Revision 1.41  2003-01-01 22:51:03  peter
 | |
|     * high value insertion changed so it works also when 2 parameters
 | |
|       are passed
 | |
| 
 | |
|   Revision 1.40  2002/12/29 14:57:50  peter
 | |
|     * unit loading changed to first register units and load them
 | |
|       afterwards. This is needed to support uses xxx in yyy correctly
 | |
|     * unit dependency check fixed
 | |
| 
 | |
|   Revision 1.39  2002/12/15 11:26:02  peter
 | |
|     * ignore vs_hidden parameters when choosing overloaded proc
 | |
| 
 | |
|   Revision 1.38  2002/12/05 14:44:38  florian
 | |
|     + oo_dispinterface added
 | |
| 
 | |
|   Revision 1.37  2002/11/29 22:31:20  carl
 | |
|     + unimplemented hint directive added
 | |
|     * hint directive parsing implemented
 | |
|     * warning on these directives
 | |
| 
 | |
|   Revision 1.36  2002/10/20 15:34:16  peter
 | |
|     * removed df_unique flag. It breaks code. For a good type=type <id>
 | |
|       a def copy is required
 | |
| 
 | |
|   Revision 1.35  2002/10/06 12:25:05  florian
 | |
|     + proper support of type <id> = type <another id>;
 | |
| 
 | |
|   Revision 1.34  2002/08/19 19:36:44  peter
 | |
|     * More fixes for cross unit inlining, all tnodes are now implemented
 | |
|     * Moved pocall_internconst to po_internconst because it is not a
 | |
|       calling type at all and it conflicted when inlining of these small
 | |
|       functions was requested
 | |
| 
 | |
|   Revision 1.33  2002/07/01 16:23:54  peter
 | |
|     * cg64 patch
 | |
|     * basics for currency
 | |
|     * asnode updates for class and interface (not finished)
 | |
| 
 | |
|   Revision 1.32  2002/05/18 13:34:18  peter
 | |
|     * readded missing revisions
 | |
| 
 | |
|   Revision 1.31  2002/05/16 19:46:44  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 1.30  2002/05/14 19:34:50  peter
 | |
|     * removed old logs and updated copyright year
 | |
| 
 | |
|   Revision 1.29  2002/05/12 16:53:10  peter
 | |
|     * moved entry and exitcode to ncgutil and cgobj
 | |
|     * foreach gets extra argument for passing local data to the
 | |
|       iterator function
 | |
|     * -CR checks also class typecasts at runtime by changing them
 | |
|       into as
 | |
|     * fixed compiler to cycle with the -CR option
 | |
|     * fixed stabs with elf writer, finally the global variables can
 | |
|       be watched
 | |
|     * removed a lot of routines from cga unit and replaced them by
 | |
|       calls to cgobj
 | |
|     * u32bit-s32bit updates for and,or,xor nodes. When one element is
 | |
|       u32bit then the other is typecasted also to u32bit without giving
 | |
|       a rangecheck warning/error.
 | |
|     * fixed pascal calling method with reversing also the high tree in
 | |
|       the parast, detected by tcalcst3 test
 | |
| 
 | |
|   Revision 1.28  2002/01/06 12:08:15  peter
 | |
|     * removed uauto from orddef, use new range_to_basetype generating
 | |
|       the correct ordinal type for a range
 | |
| 
 | |
| }
