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

5946328ed6 * CPUs not having CMOV apparently do not support the newly introduced Multibyte NOPs (Agner, Optimizing subroutines in assembly 
language, An optimization guide for x86 platforms, Page 87), so restored the 32 Bit part of the old alignment 
  bytes for use on those old CPUs and use it depending on the CPU switches

2d3ab816b0 * Tcgx86.g_concatcopy use: copy_move (mov sequence) instead of copy_string (rep 
movsb) when copying a 4 byte block on i8086, when optimizing for size. 4 movs
  are usually shorter than the instructions needed to setup rep movsb and also
  greatly reduce register pressure. This fixes i8086 snapshot building with -Os,
  Mantis #27387

d24382e8f8 * x86 AT&T writer: never ever drop "@GOTPCREL" relocation, because it results in corrupted code (at least, "mov foo@GOTPCREL(%rip),%reg" must change to "lea foo(%rip),%reg" to remain equivalent, but this must be handled elsewhere anyway. Assembler writer should just write generated code as is). 
* Added internal errors on some impossible types of references.

42d251da1c - x86 assembler readers: cleaned out operand swapping code. Operands of TInstruction are kept in AT&T order, Intel reader attaches operands right-to-left. It was effectively the same way before the change (except Intel reader attaching operands left-to-right, followed by a single swap), operand order checks all over the place were just reducing readability.

b0ff41406a * grouped all tai_real* types into a single tai_realconst type, 
to free up space for more ait_* types in taitype (can't have
    more than 32 because they have to fit in a small set)

     byte in the external assemblers

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).

c28271ab99 * NASM writer: don't force 'near' size for all non-far branches and calls, it disables NASM's capability to optimize branches into short form where possible, and thus only increases size of generated code.
