718694d1d6 * always specify an explicit alignment for tgobj.gettemp (so e.g. 
shortstring temps don't get maximum alignment)
  * changed some gettemptyed() calls into gettemp() calls (gettemptyped
    means that this temp can only be used for temps of that type,
    which is necessary for refcounted types but not for floats)

0bcaf8845f * Fixed 'mixed signed/unsigned' warnings. 
* Suppressed 2 unreachable code warnings.
* Now x86 compiler compiles without warnings and notes! It will be great to keep such state in future...

263b7abc6f * check register type also for registers in references so we are

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...
