-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.) */

-
- The standard records contain only an

- (used on 29ks and sparcs) also have a full integer for an
- addend.

S-Record handling
-DESCRIPTION
+ DESCRIPTION
Ordinary S-Records cannot hold anything but addresses and
data, so that's all that we implement.
An s record looks like:
-EXAMPLE
+ EXAMPLE
S<type><length><address><data><checksum>
-DESCRIPTION
+ DESCRIPTION
Where
o length
is the number of bytes following upto the checksum. Note that
is the sum of all the raw byte data in the record, from the length
upwards, modulo 256 and subtracted from 255.
-SUBSECTION
+ SUBSECTION
Symbol S-Record handling
-DESCRIPTION
+ DESCRIPTION
Some ICE equipment understands an addition to the standard
S-Record format; symbols and their addresses can be sent
before the data.
so a short symbol table could look like:
-EXAMPLE
+ EXAMPLE
$$ flash.x
$$ flash.c
_port6 $0
_end $8036
$$
-DESCRIPTION
+ DESCRIPTION
We allow symbols to be anywhere in the data stream - the module names
- are always ignored.
-
-*/
+ are always ignored. */

Tektronix Hex Format handling
-DESCRIPTION
+ DESCRIPTION
Tek Hex records can hold symbols and data, but not
relocations. Their main application is communication with
up and output them when it's time to close the bfd.
A TekHex record looks like:
-EXAMPLE
+ EXAMPLE
%<block length><type><checksum><stuff><cr>
-DESCRIPTION
+ DESCRIPTION
Where
o length
is the number of bytes in the record not including the % sign.
6) data record
8) termination record
-The data can come out of order, and may be discontigous. This is a
-serial protocol, so big files are unlikely, so we keep a list of 8k chunks
