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 
external assembler writer, so we can reuse the archtecture-specific
    writers to write inline assembly in LLVM IR files

cf144a7fb7 * use a dummy non-nil pointer in FSectionsUsed and FSectionsInDGROUP, because

92c831c3dd * writing of omf section attributes in the NASM asm writer rewritten to use the

4061628ffb * the i8086-msdos default code segment (in near code memory models) renamed 
'_TEXT'. This name is used in object modules, produced by Borland C and Open
  Watcom.

e09ab50724 * capitalize the group name 'DGROUP' in the generated omf object files, because 
that's how it is usually written by other 16-bit compilers

 2015-08-22 16:28:36 +00:00
nickysn
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)

6a7fff644a * align non-code sections with zeros, instead of nops in the nasm asm output 
writer, so they match the behaviour of the internal object writer (so it
  becomes easier to compare to the binary output of the omf object writer)

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)
   o factored out writing of floating point numbers as an array of
     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. 
- LDS and LES instructions do not exist on x86_64.
