Obj2 is an obj variation for OS/2. Obj2 has the following differences from obj. 1. Default attributes for a segment are ALIGN=16 and USE32. 2. Add a segment to FLAT group implicitly if 32-bit segment. 3. Recognize Unix sections .text, .rodata, .data and .bss as TEXT32, CONST32, DATA32 and BSS32 respectively for compatibility with other Unix platforms. 4. Set default classes implicitly for known segments such as TEXT32, CONST32, DATA32, BSS32 and so on. Signed-off-by: KO Myung-Hun <komh78@gmail.com>

* This header file allows configuration of which output formats
|
|
* get compiled into the NASM binary. You can configure by defining
|
|
* various preprocessor symbols beginning with "OF_", either on the
|
|
* compiler command line or at the top of this file.
|
|
*
|
|
* OF_ONLY -- only include specified object formats
|
|
* OF_name -- ensure that output format 'name' is included
|
|
* OF_NO_name -- remove output format 'name'
|
|
* OF_DOS -- ensure that 'obj', 'obj2', 'bin', 'win32' & 'win64' are included.
|
|
* OF_UNIX -- ensure that 'aout', 'aoutb', 'coff', 'elf32' & 'elf64' are in.
|
|
* OF_OTHERS -- ensure that 'bin', 'as86', 'rdf' 'macho32' & 'macho64' are in.
|
|
* OF_ALL -- ensure that all formats are included.
|
|
* note that this doesn't include 'dbg', which is
|
|
* only really useful if you're doing development
|
|
* work on NASM. Define OF_DBG if you want this.
|
|
*
|
|
* OF_DEFAULT=of_name -- ensure that 'name' is the default format.
|
|
*
|
|
* eg: -DOF_UNIX -DOF_ELF32 -DOF_DEFAULT=of_elf32 would be a suitable config
|
|
* for an average linux system.
|
|
*
|
|
* Default config = -DOF_ALL -DOF_DEFAULT=of_bin
|
|
*
|
|
* You probably only want to set these options while compiling 'nasm.c'. */
