This file is part of BFD, the Binary File Descriptor library.
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.
+ adds to the basic a.out functions support for sun3, sun4, and
+ 386 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.
+ 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
from @file{sunos.c}:
| #define TARGET_NAME "a.out-sunos-big"
-| #define VECNAME sunos_big_vec
+| #define VECNAME sparc_aout_sunos_be_vec
| #include "aoutf1.h"
requires all the names from @file{aout32.c}, and produces the jump vector
-| sunos_big_vec
+| sparc_aout_sunos_be_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
| 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}
+ in the @file{config/@var{XXX}.mt} file, and modify @file{configure.ac}
to use the
@file{@var{XXX}.mt} file (by setting "<<bfd_target=XXX>>") when your
configuration is selected. */
The file @file{aoutx.h} provides for both the @emph{standard}
and @emph{extended} forms of a.out relocation records.
- The standard records contain only an
- address, a symbol index, and a type field. The extended records
- (used on 29ks and sparcs) also have a full integer for an
- addend. */
