9b9ea15d68 + m68k: initial implementation of do_spill_replace (supports only MOVE instructions for now). Tested with qemu for Coldfire target.

1a4d6d79c5 new division helpers for ARM by Nico Erfurth. on our ARMv5 core hardware they're 22%-36% faster than the generic ones for the most common case.

235a37fad4 * moved the pass_1 handling of vecnodes for arraydefs to a new virtual method 
tvecnode.first_arraydef. This will allow overriding it in the i8086 code
  generator in order to handle huge arrays.

36d63b953e + added an i8086 specific boolean property is_huge to the tarraydef. For now it 
will only be used for indexing huge pointers (i.e. only huge arrays with the
  ado_IsConvertedPointer array option will be supported). In the distant future,
  regular huge arrays may be supported as well (but that would require
  substantially more work, including adding hugeness support to other structures
  such as records, objects and classes, so I'm not planning on doing it anytime
  soon).

e6c5c35d65 * tarraydef.create_from_pointer changed to require the actual pointerdef as a 
parameter, instead of the element def. This will allow e.g. creating huge
  arrays from huge pointers on i8086.

d46ae01589 Fix inlining of record methods across units if the unit with the method definitions is already compiled. 
symdef.pas:
  + tabstractrecorddef: implement buildderefimpl and derefimpl which works on the symtable (especially derefimpl is important here)
  - trecorddef & tobjectdef: remove buildderefimpl; it's already handled by the tabstractrecorddef one now
  - tobjectdef: remove the part of derefimpl that's already handled by tabstractrecorddef

0d96963459 * Do not promote integer comparison operations to native size if one side is a constant and its value is within range of opposite side. Instead, cast the constant to type of the opposite side. 
Comparisons are already not promoted if sides are equally signed, but this wasn't true for "unsigned vs constant" case, because constants are preferably parsed as signed.
The change considerably improves generated code for i386 and even more considerably for m68k. Tested on i386-win32.

a0934e897e * i386: improvements to 64-bit comparison code, also serves as a good base for m68k target: 
* Better handling of LOC_CREGISTER locations.
  + Support direct compares of constants with references.
  + Optimize away comparison of low dword when its result is constant (cases of "less" and "greater or equal" comparing against a constant with zero low dword).

88b58c3580 i386: added signed 64bit div/mod helpers in assembly. we have some 64bit heavy code where a direct helper results in about 8-10% of performance advantage compared to going through the generic wrapper + the unsigned function

bd5ce35130 * m68k: completely replaced 64-bit comparison code with a clone of i386 implementation. No optimizations yet, but it already makes system unit about 300 instructions shorter due to changing node location to LOC_JUMP. 
* Cleaned up 32-bit comparison code and implemented one of the optimizations (TST instruction for comparison with constant zero which can act directly on references). This makes system unit shorter by about 1000 instructions.

6f8a329b4c * use pointer arithmetic for doing address calculations, with a newly introduced 
pointer type TTinyHeapPointerArithmeticType, instead of using ptruint. This
  will allow us to use a huge pointer in i8086 far data memory models, in order
  to allow the heap to exceed 64k.

4ff597afae * call "message" rather than "cgmessage" when throwing fatal errors, because

627c83e828 * when creating a bare procdef copy, don't copy the funcret parameter. 
This is useful if you want to change the calling convention of the copy.
   o call insert_funcret_para() after creating a bare copy
  * don't copy aliasnames of copied procdefs either (can at best result
    in duplicate symbol errors)
