45337b67fe + when using the i8086 with section based smartlinking, create OMF section 
groups, named 'CGROUP' or 'CGROUP_UNITNAME', which include all the code
  sections, that need to be put in the same segment

ab47c8b899 + introduce the omf_section_primary_group function. Use it instead of 
section_belongs_to_dgroup, to allow sections to belong to groups, other than
  dgroup.

fa3ee68004 o patch by Dávid Pethes: Fixes for compilation with nasm 2.10 and higher on Win64: 
* disable generation of RVA and SECREL32 symbols (according to comment in taiconst_type, they are win32 only)
  * use lowercase cpu names (it was changed from case-insensitive names sometime after 2.10)

1f0e311fdd + allow segment override prefixes to be used as a standalone opcode in the intel 
syntax inline assembler; this is TP7 compatible and allows compiling ugly
  code, such as 'seges; db $67,$66; lodsw'

ae92973196 + added support for the retw, retnw, retfw, retd, retnd, retfd, retq, retnq and 
retfq x86 instructions. These are variants of the ret instruction with the
  return offset size set explicitly, e.g. retfw is a 16-bit far ret (i.e. pops
  a 16-bit offset and a 16-bit segment), retfd is a 32-bit far ret (pops a
  32-bit offset, followed by a 16-bit segment), etc.

2af5c9d508 * changed type used for section alignment from byte/shortint to longint, so the 
internal object writer and the internal linker support object files with
  sections with alignment >=256

acfa199b09 * in the nasm writer, only output a segment prefix for the [si] operand, in 
case there's a segment operand, different that DS (the default source
  segment) for parameterized x86 string instructions

4c75b15afe * shortened the names of the is_x86_string_instruction_op, 
is_x86_parameterless_string_instruction_op and
  is_x86_parameterized_string_instruction_op by removing 'instruction' from
  their names

0fb79946a5 + added support for the parameterized versions of the x86 string instructions 
(movs, cmps, scas, lods, stos, ins, outs) in the inline asm of the i8086, i386
  and x86_64 targets. Both intel and at&t syntax is supported.
* NEC V20/V30 instruction 'ins' (available only on the i8086 target, because it
  is incompatible with 386+ instructions) renamed 'nec_ins', to avoid conflict
  with the 186+ 'ins' instruction.

69fa837266 * NASM supports DQ already since version 2.00 (from 10 years ago) and it's already in the ait_const2str array, so use it! (doesn't mean that it works on Win64 however...)

843aee8f4a * base the CPU name, written in the beginning of each NASM assembler file on the 
nasm_cpu_name const array, which is used by the asd_cpu directive as well.
+ also enable writing this directive on i386 and x86_64 as well.

d0d940f119 * also declare Intel Nehalem and newer CPUs as 'IA64' in the NASM's 'CPU' 
directive, because NASM still doesn't support anything newer than 'PRESCOTT'
  for its CPU directive, and 'IA64' is considered (internally by NASM) to be the
  highest CPU level.

1a56a1a026 * make the asd_cpu directive (which is currently only implemented in the NASM 
asm writer), when used with a cpu_none parameter, indicate no restrictions for
  the CPU type. Under NASM, this is achieved by specifying 'IA64' as the
  CPU type, since that's the highest CPU, supported by NASM's 'CPU' directive.

178dab45d3 + added new asm directive 'asd_cpu' (specifies the CPU's instruction set) in the 
compiler's internal assembly representation. It is not yet generated by the
  compiler and is only implemented properly in the NASM writer (but will
  eventually be implemented in the other assembler writers as well, including
  the internal assembler). In the future, it is intended to allow:
  1) catching instructions, generated by the compiler and not supported by the
     target CPU, due to a bug in the code generator
  2) allowing a different instruction set to be used in inline asm blocks (I'm
     planning a new directive for that - {$asmcpu XXX}), because the code
     generator will be able to switch target CPU in the middle of the asm output
     stream

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so 
that we can use assembler writers with different conventions from the
    currently set target_asm (e.g. an x86 assembler writer for inline assembly
    in LLVM IR)

b3d0197f98 * factored out the output file handling (mostly writing data) from the

    writers to write inline assembly in LLVM IR files

778a678956 * use a 4 byte alignment for the dwarf debug sections on i8086 (not sure if 
that's correct for 16-bit dwarf, but currently the compiler emits 4-byte
  tai_aligns, so setting the section alignment to 4 avoids problems in the
  internal object writer)
