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).

597f110eb9 + added support for units with code larger than 64kb in the far code i8086
memory models. Enabled by the new directive {$hugecode on}. The directive is
  ignored in the near code memory models. When enabled, it forces each procedure
  to be in a separate segment and disables mixing near and far procedures (so
  'near' and {$F-} are ignored in this mode). Note that {$hugecode on} does not
  count as a different memory model, because you can freely link modules (units)
  compiled with {$hugecode on} and {$hugecode off}.

9a44ab2fc2 * always treat interrupt routines as far, so their address can be taken even in
{$F-} mode

d6ad2b1f8a + added support for mixing near and far procedures in the i8086 far code memory
models. The $F directive and the 'near' and 'far' procedure modifiers should
  now work as expected in the far code memory models (they are still ignored in
  the near code memory models). The compiler defaults to the {$F+} state,
  because {$F-} requires adding 'far' to a lot of procedures in the rtl,
  packages and tests.

6fe362a1b0 + added method is_far to i8086's tcpuprocdef and tcpuprocvardef
+ added helper function to i8086's symcpu is_proc_far that dispatches the call
  to the proper is_far method (because we can't make a cpu specific descendant
  of tabstractprocdef and add it there)
* all checks for (po_far in procoptions) in the i8086 code generator replaced
  with calls to is_proc_far

02495c17bd Fix a typo. The CPU specific version of "ttypesym" should be called "tcputypesym" and not "tcpuypesym".

4a79481c51 * isolated segment-related functionality of tabsolutevarsym into i386/i8086-
specific descendent classes and moved the code that deals with this in the
    code generator also to target-specific classes -> only ifdefs left in
    pdecvar

b57c95043f + support overriding tdef/tsym methods with target-specific functionality:
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls
