Revision 1.9 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 1.8 2002/03/31 20:26:38 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 1.6 2001/09/29 21:32:47 jonas
|
|
* almost all second pass typeconvnode helpers are now processor independent
|
|
* fixed converting boolean to int64/qword
|
|
* fixed register allocation bugs which could cause internalerror 10
|
|
* isnode and asnode are completely processor indepent now as well
|
|
* fpc_do_as now returns its class argument (necessary to be able to use it
|
|
properly with compilerproc)
|
|
|
|
Revision 1.5 2001/09/28 20:39:33 jonas
|
|
* changed all flow control structures (except for exception handling
|
|
related things) to processor independent code (in new ncgflw unit)
|
|
+ generic cgobj unit which contains lots of code generator helpers with
|
|
global "cg" class instance variable
|
|
+ cgcpu unit for i386 (implements processor specific routines of the above
|
|
unit)
|
|
* updated cgbase and cpubase for the new code generator units
|
|
* include ncgflw unit in cpunode unit
|
|
|
|
Revision 1.4 2001/05/18 22:31:06 peter
|
|
* tasmnode.pass_2 is independent of cpu, moved to ncgbas
|
|
* include ncgbas for independent nodes
|
|
|
|
Revision 1.3 2001/04/21 13:37:17 peter
|
|
* made tclassheader using class of to implement cpu dependent code
|
|
|
|
Revision 1.2 2000/12/31 11:14:11 jonas
|
|
+ implemented/fixed docompare() mathods for all nodes (not tested)
|
|
+ nopt.pas, nadd.pas, i386/n386opt.pas: optimized nodes for adding strings
|
|
and constant strings/chars together
|
|
* n386add.pas: don't copy temp strings (of size 256) to another temp string
|
|
when adding
|
|
|
|
Revision 1.1 2000/10/15 09:39:37 peter
|
|
* moved cpu*.pas to i386/
|
|
* renamed n386 to common cpunode
|
|
|
|
Revision 1.1 2000/10/14 10:14:47 peter
|
|
* moehrendorf oct 2000 rewrite
