* 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 1.48 2002/07/11 14:41:33 florian

* start of the new generic parameter handling
|
|
|
|
Revision 1.47 2002/07/07 09:52:34 florian
|
|
* powerpc target fixed, very simple units can be compiled
|
|
* some basic stuff for better callparanode handling, far from being finished
|
|
|
|
Revision 1.46 2002/07/01 18:46:33 peter
|
|
* internal linker
|
|
* reorganized aasm layer
|
|
|
|
Revision 1.45 2002/07/01 16:23:56 peter
|
|
* cg64 patch
|
|
* basics for currency
|
|
* asnode updates for class and interface (not finished)
|
|
|
|
Revision 1.44 2002/05/18 13:34:25 peter
|
|
* readded missing revisions
|
|
|
|
Revision 1.43 2002/05/16 19:46:51 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 1.41 2002/05/13 19:54:38 peter
|
|
* removed n386ld and n386util units
|
|
* maybe_save/maybe_restore added instead of the old maybe_push
|
|
|
|
Revision 1.40 2002/05/12 16:53:17 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 1.39 2002/04/23 19:16:35 peter
|
|
* add pinline unit that inserts compiler supported functions using
|
|
one or more statements
|
|
* moved finalize and setlength from ninl to pinline
|
|
|
|
Revision 1.38 2002/04/21 15:35:54 carl
|
|
* changeregsize -> rg.makeregsize
|
|
|
|
Revision 1.37 2002/04/19 15:39:35 peter
|
|
* removed some more routines from cga
|
|
* moved location_force_reg/mem to ncgutil
|
|
* moved arrayconstructnode secondpass to ncgld
|
|
|
|
Revision 1.36 2002/04/15 19:44:21 peter
|
|
* fixed stackcheck that would be called recursively when a stack
|
|
error was found
|
|
* generic changeregsize(reg,size) for i386 register resizing
|
|
* removed some more routines from cga unit
|
|
* fixed returnvalue handling
|
|
* fixed default stacksize of linux and go32v2, 8kb was a bit small :-)
|
|
|
|
Revision 1.35 2002/04/04 19:06:11 peter
|
|
* removed unused units
|
|
* use tlocation.size in cg.a_*loc*() routines
|
|
|
|
Revision 1.34 2002/04/02 17:11:36 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 1.33 2002/03/31 20:26:39 jonas
|
|
+ a_loadfpu_* and a_loadmm_* methods in tcg
|
|
* register allocation is now handled by a class and is mostly processor
|
|
independent (+rgobj.pas and i386/rgcpu.pas)
|
|
* temp allocation is now handled by a class (+tgobj.pas, -i386\tgcpu.pas)
|
|
* some small improvements and fixes to the optimizer
|
|
* some register allocation fixes
|
|
* some fpuvaroffset fixes in the unary minus node
|
|
* push/popusedregisters is now called rg.save/restoreusedregisters and
|
|
(for i386) uses temps instead of push/pop's when using -Op3 (that code is
|
|
also better optimizable)
|
|
* fixed and optimized register saving/restoring for new/dispose nodes
|
|
* LOC_FPU locations now also require their "register" field to be set to
|
|
R_ST, not R_ST0 (the latter is used for LOC_CFPUREGISTER locations only)
|
|
- list field removed of the tnode class because it's not used currently
|
|
and can cause hard-to-find bugs
|
|
|
|
Revision 1.32 2002/03/04 19:10:14 peter
|
|
* removed compiler warnings
|
