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.) */ + +#define KEEPIT udata.i + +#include "bfd.h" +#include "sysdep.h" +#include "safe-ctype.h" +#include "bfdlink.h" + +#include "libaout.h" +#include "libbfd.h" +#include "aout/aout64.h" +#include "aout/stab_gnu.h" +#include "aout/ar.h" + +static boolean aout_get_external_symbols PARAMS ((bfd *)); +static boolean translate_from_native_sym_flags + PARAMS ((bfd *, aout_symbol_type *)); +static boolean translate_to_native_sym_flags + PARAMS ((bfd *, asymbol *, struct external_nlist *)); +static void adjust_o_magic PARAMS ((bfd *, struct internal_exec *)); +static void adjust_z_magic PARAMS ((bfd *, struct internal_exec *)); +static void adjust_n_magic PARAMS ((bfd *, struct internal_exec *)); +reloc_howto_type * NAME(aout,reloc_type_lookup) + PARAMS ((bfd *, bfd_reloc_code_real_type)); + +/* +SUBSECTION + Relocations + +DESCRIPTION + 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.
