Revision 1.21 2000-01-07 01:14:22 peter
|
|
* updated copyright to 2000
|
|
|
|
Revision 1.20 1999/12/20 21:42:35 pierre
|
|
+ dllversion global variable
|
|
* FPC_USE_CPREFIX code removed, not necessary anymore
|
|
as we use .edata direct writing by default now.
|
|
|
|
Revision 1.19 1999/11/20 01:22:18 pierre
|
|
+ cond FPC_USE_CPREFIX (needs also some RTL changes)
|
|
this allows to use unit global vars as DLL exports
|
|
(the underline prefix seems needed by dlltool)
|
|
|
|
Revision 1.18 1999/09/16 23:05:51 florian
|
|
* m68k compiler is again compilable (only gas writer, no assembler reader)
|
|
|
|
Revision 1.17 1999/08/25 11:59:50 jonas
|
|
* changed pai386, paippc and paiapha (same for tai*) to paicpu (taicpu)
|
|
|
|
Revision 1.16 1999/04/07 15:31:18 pierre
|
|
* all formaldefs are now a sinlge definition
|
|
cformaldef (this was necessary for double_checksum)
|
|
+ small part of double_checksum code
|
|
|
|
Revision 1.15 1998/12/11 00:03:03 peter
|
|
+ globtype,tokens,version unit splitted from globals
|
|
|
|
Revision 1.14 1998/11/05 12:02:38 peter
|
|
* released useansistring
|
|
* removed -Sv, its now available in fpc modes
|
|
|
|
Revision 1.13 1998/10/22 17:11:14 pierre
|
|
+ terminated the include exclude implementation for i386
|
|
* enums inside records fixed
|
|
|
|
Revision 1.12 1998/10/21 15:12:53 pierre
|
|
* bug fix for IOCHECK inside a procedure with iocheck modifier
|
|
* removed the GPF for unexistant overloading
|
|
(firstcall was called with procedinition=nil !)
|
|
* changed typen to what Florian proposed
|
|
gentypenode(p : pdef) sets the typenodetype field
|
|
and resulttype is only set if inside bt_type block !
|
|
|
|
Revision 1.11 1998/10/16 13:12:47 pierre
|
|
* added vmt_offsets in destructors code also !!!
|
|
* vmt_offset code for m68k
|
|
|
|
Revision 1.10 1998/10/14 16:53:04 pierre

* bug in in_inc_x for constants out of range for A_ADDQ fixed
|
|
|
|
Revision 1.9 1998/10/14 11:28:20 florian
|
|
* emitpushreferenceaddress gets now the asmlist as parameter
|
|
* m68k version compiles with -duseansistrings
|
|
|
|
Revision 1.8 1998/10/14 08:08:52 pierre
|
|
* following Peters remark, removed all ifdef in
|
|
the systems unit enums
|
|
* last bugs of cg68k removed for sysamiga
|
|
(sysamiga assembles with as68k !!)
|
|
|
|
Revision 1.7 1998/10/13 16:50:08 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 1.6 1998/10/06 20:48:58 peter
