+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.) */
