263b7abc6f * check register type also for registers in references so we are 
not mixing addressregisters and intregisters on m68k

335bc9fd46 + PIC support for darwin/ppc32 (-Cg works now, no regressions in test 
suite compiled with -Cg compared to without -Cg)
  + support for using a virtual register as PIC/got base register
  * moved got loading code from ncgutil to cgobj/cgcpu (can't test whether
    it didn't break anything under linux/i386, because "make cycle OPT=-Cg"
    was already broken due to the *prt*.as -> si_*.pp changes)

21293f5818 + Add common type integer promotion. 
- {$intpromotion common_type} or -CIcommon_type switches to common type promotion.
    - {$intpromotion native_integer} or -CIcommon_type switches to current behaviour.
    - Default in tp mode is common_type, native_integer in other modes
    - Compiler can cycle with -CIcommon_type
    - Still needs checking on other architectures than i386

dc71fc8290 * make sure live_start/end is never a tai_regalloc, as those can be 
removed by the register allocator and thus become invalid. This fixed
    make cycle with -Or for ppc, but I'm not sure what the warning on
    symsym.pas:1663 means. Since the tlocation change, even regular make
    cycle doesn't work anymore though...
