* delphi also has pointer archimetic
Revision 1.78 2002/12/07 14:27:07 carl
* 3% memory optimization
* changed some types
+ added type checking with different size for call node and for
parameters
Revision 1.77 2002/12/06 17:50:00 peter
* amiga fixes merged
Revision 1.76 2002/12/01 22:07:41 carl
* warning of portabilitiy problems with parasize / localsize
+ some added documentation
Revision 1.75 2002/11/30 23:13:48 carl
- cs_fp_emulation is no longer automatic for m68k target
Revision 1.74 2002/11/30 11:08:46 carl
* fix bug n last commit (this bug was only detected gby 1.0.x, fixed)
Revision 1.73 2002/11/30 00:34:20 pierre
* remove double in delphimodeswitches to allow compilation with -Cr option
Revision 1.72 2002/11/29 22:31:19 carl
+ unimplemented hint directive added
* hint directive parsing implemented
* warning on these directives
Revision 1.71 2002/11/20 10:11:46 mazen
+ TSearchPathList.AddPath supports a local path in addition to file name
Revision 1.70 2002/11/16 14:49:12 carl
- browser information is off by default
Revision 1.69 2002/11/15 01:58:47 peter
* merged changes from 1.0.7 up to 04-11
- -V option for generating bug report tracing
- more tracing for option parsing
- errors for cdecl and high()
- win32 import stabs
- 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 1.68 2002/11/09 15:38:39 carl
+ added var_align/const_align routines
Revision 1.67 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 1.66 2002/09/05 19:28:29 peter
* removed repetitive pass counting
* display heapsize also for extdebug
Revision 1.65 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 1.64 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 1.63 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 1.62 2002/07/28 20:45:22 florian
+ added direct assembler reader for PowerPC
Revision 1.61 2002/07/20 17:12:42 florian
+ source code page support
Revision 1.60 2002/07/01 18:46:22 peter

+ start of tassembler / tmodulebase class cleanup
Revision 1.55 2002/04/20 21:32:23 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 1.54 2002/04/07 13:24:30 carl
+ moved constant from cpuinfo, these are NOT cpu specific
constant, but more related to compiler functionality.
Revision 1.53 2002/04/02 17:11:28 peter
* tlocation,treference update
* LOC_CONSTANT added for better constant handling
* secondadd splitted in multiple routines

(this is compatible with Kylix). This saves a lot of push/pop especially
with string operations
* adapted some routines to use the new cg methods
Revision 1.52 2002/03/28 16:07:52 armin
+ initialize threadvars defined local in units
