Revision 1.14 2000-01-07 01:14:22 peter
|
|
* updated copyright to 2000
|
|
|
|
Revision 1.13 1999/12/22 01:01:47 peter
|
|
- removed freelabel()
|
|
* added undefined label detection in internal assembler, this prevents
|
|
a lot of ld crashes and wrong .o files
|
|
* .o files aren't written anymore if errors have occured
|
|
* inlining of assembler labels is now correct
|
|
|
|
Revision 1.12 1999/11/09 23:06:44 peter
|
|
* esi_offset -> selfpointer_offset to be newcg compatible
|
|
* hcogegen -> cgbase fixes for newcg
|
|
|
|
Revision 1.11 1999/09/27 23:44:48 peter
|
|
* procinfo is now a pointer
|
|
* support for result setting in sub procedure
|
|
|
|
Revision 1.10 1999/09/16 23:05:51 florian
|
|
* m68k compiler is again compilable (only gas writer, no assembler reader)
|
|
|
|
Revision 1.9 1999/08/25 11:59:49 jonas
|
|
* changed pai386, paippc and paiapha (same for tai*) to paicpu (taicpu)
|
|
|
|
Revision 1.8 1998/12/11 00:03:02 peter
|
|
+ globtype,tokens,version unit splitted from globals
|
|
|
|
Revision 1.7 1998/10/14 11:28:19 florian
|
|
* emitpushreferenceaddress gets now the asmlist as parameter
|
|
* m68k version compiles with -duseansistrings
|
|
|
|
Revision 1.6 1998/10/13 16:50:07 pierre
|
|
* undid some changes of Peter that made the compiler wrong
|
|
for m68k (I had to reinsert some ifdefs)
|
|
* removed several memory leaks under m68k
|
|
* removed the meory leaks for assembler readers
|
|
* cross compiling shoud work again better
|
|
( crosscompiling sysamiga works
|
|
but as68k still complain about some code !)
|
|
|
|
Revision 1.5 1998/09/17 09:42:24 peter
|
|
+ pass_2 for cg386
|
|
* Message() -> CGMessage() for pass_1/pass_2
|
|
|
|
Revision 1.4 1998/09/14 10:43:58 peter
|
|
* all internal RTL functions start with FPC_
|
|
|
|
Revision 1.3 1998/09/04 08:41:47 peter
|
|
* updated some error messages
|
|
|
|
Revision 1.2 1998/09/01 12:48:01 peter
|
|
* use pdef^.size instead of orddef^.typ
|
|
|
|
Revision 1.1 1998/09/01 09:07:09 peter
|
|
* m68k fixes, splitted cg68k like cgi386
