* 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
* 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
* writing of procvar headers is more complete (mention var/const/out for
paras, add "of object" if applicable)
+ error if declaring explicit self para as var/const
* fixed mangled name of procedures which contain an explicit self para
* parsing para's should be slightly faster because mangled name of
procedure is only updated once instead of after parsing each para
(all merged from fixes)
* -Oa argument supports more alignment settings that can be specified
per type: PROC,LOOP,VARMIN,VARMAX,CONSTMIN,CONSTMAX,RECORDMIN
RECORDMAX,LOCALMIN,LOCALMAX. It is possible to set the mimimum
required alignment and the maximum usefull alignment. The final
alignment will be choosen per variable size dependent on these
settings
