Revision 1.6 2003/10/03 14:16:48 marco
* -XP<prefix> support
Revision 1.5 2003/04/27 07:29:52 peter
* aktprocdef cleanup, aktprocdef is now always nil when parsing
a new procdef declaration
* aktprocsym removed
* lexlevel removed, use symtable.symtablelevel instead
* implicit init/final code uses the normal genentry/genexit
* funcret state checking updated for new funcret handling
Revision 1.4 2003/04/26 09:16:08 peter
* .o files belonging to the unit are first searched in the same dir
as the .ppu
Revision 1.3 2002/10/05 12:43:29 carl
* fixes for Delphi 6 compilation
(warning : Some features do not work under Delphi)
Revision 1.2 2002/09/09 17:34:17 peter
* tdicationary.replace added to replace and item in a dictionary. This
is only allowed for the same name
* varsyms are inserted in symtable before the types are parsed. This
fixes the long standing "var longint : longint" bug
- consume_idlist and idstringlist removed. The loops are inserted
at the callers place and uses the symtable for duplicate id checking
Revision 1.1 2002/09/06 15:03:51 carl
* moved files to systems directory
Revision 1.24 2002/09/03 16:26:28 daniel
* Make Tprocdef.defs protected
Revision 1.23 2002/08/12 15:08:44 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 1.22 2002/08/11 14:32:32 peter
* renamed current_library to objectlibrary
Revision 1.21 2002/08/11 13:24:19 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 1.20 2002/07/26 21:15:45 florian
* rewrote the system handling
Revision 1.19 2002/07/01 18:46:34 peter
* internal linker
* reorganized aasm layer
Revision 1.18 2002/05/18 13:34:26 peter
* readded missing revisions
Revision 1.17 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 1.15 2002/04/22 18:19:22 carl
- remove use_bound_instruction field
Revision 1.14 2002/04/20 21:43:18 carl
* fix stack size for some targets
+ add offset to parameters from frame pointer info.
- remove some unused stuff
Revision 1.13 2002/04/19 15:46:04 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 1.12 2002/04/15 19:16:57 carl
- remove size_of_pointer field
Revision 1.11 2002/01/29 21:27:34 peter
* default alignment changed to 4 bytes for locals and static const,var
