|
|
|
|

Revision 1.20 2002/10/05 12:43:25 carl
|
|
* fixes for Delphi 6 compilation
|
|
(warning : Some features do not work under Delphi)
|
|
|
|
Revision 1.19 2002/08/18 20:06:23 peter
|
|
* inlining is now also allowed in interface
|
|
* renamed write/load to ppuwrite/ppuload
|
|
* tnode storing in ppu
|
|
* nld,ncon,nbas are already updated for storing in ppu
|
|
|
|
Revision 1.18 2002/08/11 14:32:26 peter
|
|
* renamed current_library to objectlibrary
|
|
|
|
Revision 1.17 2002/08/11 13:24:11 peter
|
|
* saving of asmsymbols in ppu supported
|
|
* asmsymbollist global is removed and moved into a new class
|
|
tasmlibrarydata that will hold the info of a .a file which
|
|
corresponds with a single module. Added librarydata to tmodule
|
|
to keep the library info stored for the module. In the future the
|
|
objectfiles will also be stored to the tasmlibrarydata class
|
|
* all getlabel/newasmsymbol and friends are moved to the new class
|
|
|
|
Revision 1.16 2002/08/10 17:15:06 jonas
|
|
* endianess fix
|
|
|
|
Revision 1.15 2002/07/23 12:34:30 daniel
|
|
* Readded old set code. To use it define 'oldset'. Activated by default
|
|
for ppc.
|
|
|
|
Revision 1.14 2002/07/22 11:48:04 daniel
|
|
* Sets are now internally sets.
|
|
|
|
Revision 1.13 2002/07/20 11:57:53 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 1.12 2002/07/01 18:46:22 peter
|
|
* internal linker
|
|
* reorganized aasm layer
|
|
|
|
Revision 1.11 2002/07/01 16:23:53 peter
|
|
* cg64 patch
|
|
* basics for currency
|
|
* asnode updates for class and interface (not finished)
|
|
|
|
Revision 1.10 2002/05/18 13:34:09 peter
|
|
* readded missing revisions
|
|
|
|
Revision 1.9 2002/05/16 19:46:37 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 1.7 2002/04/04 19:05:57 peter
|
|
* removed unused units
|
|
* use tlocation.size in cg.a_*loc*() routines
|
|
|
|
Revision 1.6 2002/04/02 17:11:28 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 1.5 2002/03/31 20:26:34 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 1.4 2002/02/26 09:12:39 jonas
|
|
* fixed problem when compiling the compiler with Delphi (reported by
|
|
"Luc Langlois" <L_Langlois@Videotron.ca>) (lo/hi don't work as in FPC
|
|
when used with int64's under Delphi)
