 | |
|     * procvar directive parsing fixes
 | |
| 
 | |
|   Revision 1.69  2003/09/23 17:56:05  peter
 | |
|     * locals and paras are allocated in the code generation
 | |
|     * tvarsym.localloc contains the location of para/local when
 | |
|       generating code for the current procedure
 | |
| 
 | |
|   Revision 1.68  2003/07/02 22:18:04  peter
 | |
|     * paraloc splitted in callerparaloc,calleeparaloc
 | |
|     * sparc calling convention updates
 | |
|

 | |
|     * aktprocdef renamed to current_procdef
 | |
|     * procinfo renamed to current_procinfo
 | |
|     * procinfo will now be stored in current_module so it can be
 | |

 | |
|     * gen_main_procsym changed to create_main_proc and release_main_proc
 | |
|       to also generate a tprocinfo structure
 | |
|     * fixed unit implicit initfinal
 | |
| 
 | |
|   Revision 1.66  2003/04/27 07:29:50  peter
 | |
|     * current_procdef cleanup, current_procdef is now always nil when parsing
 | |
|       a new procdef declaration
 | |
|     * aktprocsym removed
 | |

 | |
| 
 | |
|   Revision 1.65  2003/04/01 16:17:15  peter
 | |
|     * reset symbol for unique types
 | |
| 
 | |
|   Revision 1.64  2003/01/05 15:54:15  florian
 | |
|     + added proper support of type = type <type>; for simple types
 | |
| 
 | |
|   Revision 1.63  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 1.62  2002/12/05 19:27:40  carl
 | |
|     - remove lower in hint
 | |
| 
 | |
|   Revision 1.61  2002/11/25 18:43:32  carl
 | |
|    - removed the invalid if <> checking (Delphi is strange on this)
 | |
|    + implemented abstract warning on instance creation of class with
 | |
|       abstract methods.
 | |
|    * some error message cleanups
 | |
| 
 | |
|   Revision 1.60  2002/11/23 22:50:06  carl
 | |
|     * some small speed optimizations
 | |
|     + added several new warnings/hints
 | |
| 
 | |
|   Revision 1.59  2002/11/17 16:31:56  carl
 | |
|     * memory optimization (3-4%) : cleanup of tai fields,
 | |
|        cleanup of tdef and tsym fields.
 | |
|     * make it work for m68k
 | |
| 
 | |
|   Revision 1.58  2002/11/15 16:29:30  peter
 | |
|     * made tasmsymbol.refs private (merged)
 | |
| 
 | |
|   Revision 1.57  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 1.56  2002/10/19 15:09:25  peter
 | |
|     + tobjectdef.members_need_inittable that is used to generate only the
 | |
|       inittable when it is really used. This saves a lot of useless calls
 | |
|       to fpc_finalize when destroying classes
 | |
| 
 | |
|   Revision 1.55  2002/10/14 19:45:02  peter
 | |
|     * only allow threadvar when threading switch is defined
 | |
| 
 | |
|   Revision 1.54  2002/10/06 12:25:05  florian
 | |
|     + proper support of type <id> = type <another id>;
 | |
| 
 | |
|   Revision 1.53  2002/08/25 19:25:19  peter
 | |
|     * sym.insert_in_data removed
 | |
|     * symtable.insertvardata/insertconstdata added
 | |
|     * removed insert_in_data call from symtable.insert, it needs to be
 | |
|       called separatly. This allows to deref the address calculation
 | |
|     * procedures now calculate the parast addresses after the procedure
 | |
|       directives are parsed. This fixes the cdecl parast problem
 | |
|     * push_addr_param has an extra argument that specifies if cdecl is used
 | |
|       or not
 | |
| 
 | |
|   Revision 1.52  2002/08/12 15:08:40  carl
 | |
|     + stab register indexes for powerpc (moved from gdb to cpubase)
 | |
|     + tprocessor enumeration moved to cpuinfo
 | |
|     + linker in target_info is now a class
 | |
|     * many many updates for m68k (will soon start to compile)
 | |
|     - removed some ifdef or correct them for correct cpu
 | |
| 
 | |
|   Revision 1.51  2002/08/11 14:32:27  peter
 | |
|     * renamed current_library to objectlibrary
 | |
| 
 | |
|   Revision 1.50  2002/08/11 13:24:12  peter
 | |
|     * saving of asmsymbols in ppu supported
 | |
|     * asmsymbollist global is removed and moved into a new class
 | |
|       tasmlibrarydata that will hold the info of a .a file which
 | |
|       corresponds with a single module. Added librarydata to tmodule
 | |
|       to keep the library info stored for the module. In the future the
 | |
|       objectfiles will also be stored to the tasmlibrarydata class
 | |
|     * all getlabel/newasmsymbol and friends are moved to the new class
 | |
| 
 | |
|   Revision 1.49  2002/07/29 21:23:43  florian
 | |
|     * more fixes for the ppc
 | |
|     + wrappers for the tcnvnode.first_* stuff introduced
 | |
| 
 | |
|   Revision 1.48  2002/07/01 18:46:25  peter
 | |
|     * internal linker
 | |
|     * reorganized aasm layer
 | |
| 
 | |
|   Revision 1.47  2002/06/12 13:20:29  jonas
 | |
|     * fix from Florian for init/final info of forward classes
 | |
| 
 | |
|   Revision 1.46  2002/05/18 13:34:12  peter
 | |
|     * readded missing revisions
 | |
| 
 | |
|   Revision 1.45  2002/05/16 19:46:42  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 1.43  2002/05/12 16:53:08  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 1.42  2002/04/19 15:46:02  peter
 | |
|     * mangledname rewrite, tprocdef.mangledname is now created dynamicly
 | |
|       in most cases and not written to the ppu
 | |
|     * add mangeledname_prefix() routine to generate the prefix of
 | |
|       manglednames depending on the current procedure, object and module
 | |
|     * removed static procprefix since the mangledname is now build only
 | |
|       on demand from tprocdef.mangledname
 | |
| 
 | |
|   Revision 1.41  2002/03/04 17:54:59  peter
 | |
|     * allow oridinal labels again
