-SECTION
- a.out backends
-
-
-DESCRIPTION
-
- BFD supports a number of different flavours of a.out format,
- though the major differences are only the sizes of the
- structures on disk, and the shape of the relocation
- information.
-
- The support is split into a basic support file @file{aoutx.h}
- and other files which derive functions from the base. One
- derivation file is @file{aoutf1.h} (for a.out flavour 1), and
- adds to the basic a.out functions support for sun3, sun4, 386
- and 29k a.out files, to create a target jump vector for a
- specific target.
-
- This information is further split out into more specific files
- for each machine, including @file{sunos.c} for sun3 and sun4,
- @file{newsos3.c} for the Sony NEWS, and @file{demo64.c} for a
- demonstration of a 64 bit a.out format.
-
- The base file @file{aoutx.h} defines general mechanisms for
- reading and writing records to and from disk and various
- other methods which BFD requires. It is included by
- @file{aout32.c} and @file{aout64.c} to form the names
- <<aout_32_swap_exec_header_in>>, <<aout_64_swap_exec_header_in>>, etc.
-
- As an example, this is what goes on to make the back end for a
- sun4, from @file{aout32.c}:
-
-| #define ARCH_SIZE 32
-| #include "aoutx.h"
-
- Which exports names:
-
-| ...
-| aout_32_canonicalize_reloc
-| aout_32_find_nearest_line
-| aout_32_get_lineno
-| aout_32_get_reloc_upper_bound
-| ...
-
- from @file{sunos.c}:
-
-| #define TARGET_NAME "a.out-sunos-big"
-| #define VECNAME sunos_big_vec
-| #include "aoutf1.h"
-
- requires all the names from @file{aout32.c}, and produces the jump vector
-
-| sunos_big_vec
-
- The file @file{host-aout.c} is a special case. It is for a large set
- of hosts that use ``more or less standard'' a.out files, and
- for which cross-debugging is not interesting. It uses the
- standard 32-bit a.out support routines, but determines the
- file offsets and addresses of the text, data, and BSS
- sections, the machine architecture and machine type, and the
- entry point address, in a host-dependent manner. Once these
- values have been determined, generic code is used to handle
- the object file.
-
- When porting it to run on a new system, you must supply:
-
-| HOST_PAGE_SIZE
-| HOST_SEGMENT_SIZE
-| HOST_MACHINE_ARCH (optional)
-| HOST_MACHINE_MACHINE (optional)
-| HOST_TEXT_START_ADDR
-| HOST_STACK_END_ADDR
-
- in the file @file{../include/sys/h-@var{XXX}.h} (for your host). These
- values, plus the structures and macros defined in @file{a.out.h} on
- your host system, will produce a BFD target that will access
- ordinary a.out files on your host. To configure a new machine
- to use @file{host-aout.c}, specify:
-
-| TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
-| TDEPFILES= host-aout.o trad-core.o
-
- in the @file{config/@var{XXX}.mt} file, and modify @file{configure.in}
- to use the
- @file{@var{XXX}.mt} file (by setting "<<bfd_target=XXX>>") when your
- configuration is selected.

-/* Some assumptions:
- * Any BFD with D_PAGED set is ZMAGIC, and vice versa.
- Doesn't matter what the setting of WP_TEXT is on output, but it'll
- get set on input.
- * Any BFD with D_PAGED clear and WP_TEXT set is NMAGIC.
- * Any BFD with both flags clear is OMAGIC.
- (Just want to make these explicit, so the conditions tested in this
- file make sense if you're more familiar with a.out than with BFD.) */
