|
* default calling convention changed to stdcall
|
|
|
|
Revision 1.42 2003/09/07 22:09:35 peter
|
|
* preparations for different default calling conventions
|
|

|
Revision 1.41 2003/09/04 21:37:29 olle
|
|
+ added new lagnuage mode: MAC

|
|
allocator
|
|
* Some preventive changes to i386 spillinh code
|
|
|
|
Revision 1.38 2003/04/27 11:21:32 peter
|
|
* aktprocdef renamed to current_procdef
|
|
* procinfo renamed to current_procinfo
|
|
* procinfo will now be stored in current_module so it can be
|
|
cleaned up properly
|
|
* gen_main_procsym changed to create_main_proc and release_main_proc
|
|
to also generate a tprocinfo structure
|
|
* fixed unit implicit initfinal
|
|
|
|
Revision 1.37 2003/04/27 07:29:50 peter
|
|
* current_procdef cleanup, current_procdef 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 1.36 2003/04/22 23:50:22 peter
|
|
* firstpass uses expectloc
|
|
* checks if there are differences between the expectloc and
|
|
location.loc from secondpass in EXTDEBUG
|
|
|
|
Revision 1.35 2003/03/08 08:59:07 daniel
|
|
+ $define newra will enable new register allocator
|
|
+ getregisterint will return imaginary registers with $newra
|
|
+ -sr switch added, will skip register allocation so you can see
|
|
the direct output of the code generator before register allocation
|
|
|
|
Revision 1.34 2002/10/16 19:01:43 peter
|
|
+ $IMPLICITEXCEPTIONS switch to turn on/off generation of the
|
|
implicit exception frames for procedures with initialized variables
|
|
and for constructors. The default is on for compatibility
|
|
|
|
Revision 1.33 2002/10/14 19:43:41 peter
|
|
* threading switch, defines the symbol FPC_THREADING
|
|
|
|
Revision 1.32 2002/10/05 12:43:24 carl
|
|
* fixes for Delphi 6 compilation

|
(warning : Some features do not work under Delphi)
|
|
|
|
Revision 1.31 2002/08/19 19:36:42 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 1.30 2002/08/12 15:08:39 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 1.29 2002/08/06 20:55:20 florian

+ try to fix temp allocation (still in ifdef)
|
|
+ generic constructor calls

Revision 1.23 2002/05/12 16:53:05 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 1.22 2002/04/21 19:02:03 peter
|

* removed newn and disposen nodes, the code is now directly
|
|
inlined from pexpr
|
|
* -an option that will write the secondpass nodes to the .s file, this
|
|
requires EXTDEBUG define to actually write the info
|
|
* fixed various internal errors and crashes due recent code changes
|
|
|
|
Revision 1.21 2002/03/24 19:05:59 carl
