- win32 records<=8 are returned in eax:edx (turned off by default)
- heaptrc update
- more info for temp management in .s file with EXTDEBUG
Revision 1.87 2002/10/23 17:07:40 peter
* fix -n that was broken in the previous commit
Revision 1.86 2002/10/23 16:57:16 peter
* first search for fpc.cfg instead of deprecated ppc386.cfg
* parse commandline options first before searching configfile so -vt
can be used to display the searched files
Revision 1.85 2002/10/13 21:33:01 peter
* define HASTHREADVAR
Revision 1.84 2002/10/02 18:20:52 peter
* Copy() is now internal syssym that calls compilerprocs
Revision 1.83 2002/09/22 14:02:35 carl
* stack checking cannot be called before system unit is initialized
* MC68020 define
Revision 1.82 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 1.81 2002/08/10 14:46:29 carl
+ moved target_cpu_string to cpuinfo
* renamed asmmode enum.
* assembler reader has now less ifdef's
* move from nppcmem.pas -> ncgmem.pas vec. node.
Revision 1.80 2002/08/09 19:15:41 carl
- removed newcg define
Revision 1.79 2002/07/26 22:22:10 florian
* several PowerPC related fixes to get forward with system unit compilation
Revision 1.78 2002/07/26 21:15:39 florian
* rewrote the system handling
Revision 1.77 2002/07/20 17:16:03 florian
+ source code page support
Revision 1.76 2002/07/04 20:43:01 florian
* first x86-64 patches
Revision 1.75 2002/07/01 18:46:24 peter
* internal linker
* reorganized aasm layer
Revision 1.74 2002/07/01 16:23:53 peter
* cg64 patch
* basics for currency
* asnode updates for class and interface (not finished)
Revision 1.73 2002/05/18 13:34:11 peter
* readded missing revisions
Revision 1.72 2002/05/16 19:46:41 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 1.70 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 1.69 2002/04/21 19:02:04 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 1.68 2002/04/20 21:32:24 carl
+ generic FPC_CHECKPOINTER
+ first parameter offset in stack now portable
* rename some constants
+ move some cpu stuff to other units
- remove unused constents
* fix stacksize for some targets
* fix generic size problems which depend now on EXTEND_SIZE constant
Revision 1.67 2002/04/07 10:22:35 carl
+ CPU defines now depends on current target
Revision 1.66 2002/04/04 19:05:58 peter
* removed unused units
* use tlocation.size in cg.a_*loc*() routines
Revision 1.65 2002/04/04 18:39:45 carl
+ added wdosx support (patch from Pavel)
