/*
 * outform.h    header file for binding output format drivers to the
 *              remainder of the code in the Netwide Assembler
 */

/*
 * 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', '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'. */
