Revision 1.5 2002/11/25 17:43:27 peter
* splitted defbase in defutil,symutil,defcmp
* merged isconvertable and is_equal into compare_defs(_ext)
* made operator search faster by walking the list only once
Revision 1.4 2002/11/18 17:32:00 peter
* pass proccalloption to ret_in_xxx and push_xxx functions

* first part of procinfo rewrite
Revision 1.1 2002/08/10 14:47:50 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 1.21 2002/07/20 11:58:05 florian
* types.pas renamed to defbase.pas because D6 contains a types
unit so this would conflicts if D6 programms are compiled
+ Willamette/SSE2 instructions to assembler added
Revision 1.20 2002/07/11 14:41:34 florian

* readded missing revisions
Revision 1.17 2002/05/16 19:46:52 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 2002/05/12 16:53:18 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 1.14 2002/04/15 19:12:09 carl
+ target_info.size_of_pointer -> pointer_size
+ some cleanup of unused types/variables
* move several constants from cpubase to their specific units
(where they are used)
+ att_Reg2str -> gas_reg2str
+ int_reg2str -> std_reg2str
Revision 1.13 2002/04/14 17:01:52 carl

Revision 1.18 2002/05/12 16:53:18 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

* 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

Revision 1.17 2002/04/15 19:12:09 carl
+ target_info.size_of_pointer -> pointer_size
+ some cleanup of unused types/variables
* move several constants from cpubase to their specific units

+ att_Reg2str -> gas_reg2str
+ int_reg2str -> std_reg2str
Revision 1.16 2002/04/04 19:06:13 peter
* removed unused units
* use tlocation.size in cg.a_*loc*() routines
Revision 1.15 2002/04/02 17:11:39 peter
* tlocation,treference update
* LOC_CONSTANT added for better constant handling
* secondadd splitted in multiple routines
* location_force_reg added for loading a location to a register
of a specified size
* secondassignment parses now first the right and then the left node
(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 1.14 2002/01/24 18:25:53 peter
* implicit result variable generation for assembler routines
* removed m_tp modeswitch, use m_tp7 or not(m_fpc) instead
