d6de2c03cb * generic part of r26050 from the hlcgllvm branch: made tcgvecnode hlcg-safe 
o in particular, add tdef size information to the update_reference*()
     methods, and factored out offset adjustments into its own method
   o also make sure the passed size to update_reference*() corresponds to the
     actual size of the index, as it's no longer guaranteed to be ptruint
     since the previous commit

a637fbe596 * moved all g_exception_*() methods to hlcgobj and cleaned them up (no more 
hardcoded registers for the most part)
  + added extra g_exception_discard_reason() that can be called when we only
    want to get rid of the currently pushed exception reason, and don't have
    to load it (so it can do nothing on platforms that don't use push/pop)

nickysn
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).

1910177cf0 + added heapmax support to the $M directive on i8086-msdos. It is currently 
only implemented in the near data memory models. The far data models support
  is still a TODO.

7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e. 
the value set by -Ch or the second parameter to the $M directive). This is
  equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
  has at least this amount of heap space available (otherwise DOS will show a
  'not enough memory' error and will refuse to load the program).

dc628b8969 * x86: Completely skip instructions that do not exist for target CPU bit width. The existing behavior of writing mnemonics and properties but no encoding allows an invalid instruction to be recognized by assembler reader or even generated by compiler, but it but won't assemble anyway.

73d7f2aa18 * let the compiler generate the stack segment in i8086 near data memory models 
as well. Even though, in these models, the stack is dynamically allocated
  (because it goes on top of the heap, but the heap is variable size), there are
  still benefits:
  1) the program will run on a larger stack during initialization, before the
     actual stack (and heap) are ready
  2) in cases, when the system is extremely low on memory, DOS will reject to
     load the program if there's not enough memory for the stack the program
     requires. This way the startup code can be further simplified by omitting
     the 'not enough memory' check in the future (when we add the minimum heap
     size to the executable reserved space as well).

3cc8ff11e3 + generate the stack segment for i8086 far data memory models from within fpc 
itself (instead of having a fixed 16k stack in the startup code). This allows
  setting the stack size in these models with the -Cs option.
