* reverted Peter's alloctemp patch; hopefully properly
Revision 1.48 2003/12/03 23:13:20 peter
* delayed paraloc allocation, a_param_*() gets extra parameter
if it needs to allocate temp or real paralocation
* optimized/simplified int-real loading
Revision 1.47 2003/10/10 17:48:13 peter
* old trgobj moved to x86/rgcpu and renamed to trgx86fpu
* tregisteralloctor renamed to trgobj
* removed rgobj from a lot of units
* moved location_* and reference_* to cgobj
* first things for mmx register allocation
Revision 1.46 2003/10/09 21:31:37 daniel
* Register allocator splitted, ans abstract now
Revision 1.45 2003/10/08 19:19:45 peter
* set_varstate cleanup
Revision 1.44 2003/10/05 21:21:52 peter
* c style array of const generates callparanodes
* varargs paraloc fixes
Revision 1.43 2003/10/01 20:34:48 peter
* procinfo unit contains tprocinfo
* cginfo renamed to cgbase
* moved cgmessage to verbose
* fixed ppc and sparc compiles
Revision 1.42 2003/09/10 08:31:47 marco
* Patch from Peter for paraloc
Revision 1.41 2003/09/07 22:09:35 peter
* preparations for different default calling conventions
* various RA fixes
Revision 1.40 2003/09/03 15:55:00 peter
* NEWRA branch merged
Revision 1.39.2.1 2003/08/29 17:28:59 peter
* next batch of updates
Revision 1.39 2003/07/23 11:01:14 jonas
* several rg.allocexplicitregistersint/rg.deallocexplicitregistersint
pairs round calls to helpers
Revision 1.38 2003/07/05 20:07:24 jonas
* fixed range check errors
Revision 1.37 2003/06/13 21:19:30 peter
* current_procdef removed, use current_procinfo.procdef instead
Revision 1.36 2003/06/07 18:57:04 jonas
+ added freeintparaloc
* ppc get/freeintparaloc now check whether the parameter regs are
properly allocated/deallocated (and get an extra list para)
* ppc a_call_* now internalerrors if pi_do_call is not yet set
* fixed lot of missing pi_do_call's
Revision 1.35 2003/06/03 21:11:09 peter
* cg.a_load_* get a from and to size specifier
* makeregsize only accepts newregister
* i386 uses generic tcgnotnode,tcgunaryminus
Revision 1.34 2003/06/01 21:38:06 peter

* a_load_reg_reg() now has two size parameters: source and dest. This
allows some optimizations on architectures that don't encode the
register size in the register name.
Revision 1.13 2002/08/13 18:01:52 carl
* rename swatoperands to swapoperands
+ m68k first compilable version (still needs a lot of testing):
