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.) */ - +/* Start of modified aoutx.h. */ #define KEEPIT udata.i -#include <string.h> /* For strchr and friends */ +#include <string.h> /* For strchr and friends. */ #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" @@ -328,61 +161,30 @@ DESCRIPTION #undef N_REG #undef N_FN #undef N_EXT -#define N_TYPE 0x1f /* type mask */ -#define N_UNDF 0x00 /* undefined */ -#define N_ABS 0x01 /* absolute */ -#define N_TEXT 0x02 /* text segment */ -#define N_DATA 0x03 /* data segment */ -#define N_BSS 0x04 /* bss segment */ -#define N_REG 0x14 /* register symbol */ -#define N_FN 0x1f /* file name */ - -#define N_EXT 0x20 /* external flag */ +#define N_TYPE 0x1f /* Type mask. */ +#define N_UNDF 0x00 /* Undefined. */ +#define N_ABS 0x01 /* Absolute. */ +#define N_TEXT 0x02 /* Text segment. */ +#define N_DATA 0x03 /* Data segment. */ +#define N_BSS 0x04 /* Bss segment. */ +#define N_REG 0x14 /* Register symbol. */ +#define N_FN 0x1f /* File name. */ +#define N_EXT 0x20 /* External flag. */ #define RELOC_SIZE 2 -#define RELFLG 0x0001 /* pc-relative flag */ -#define RTYPE 0x000e /* type mask */ -#define RIDXMASK 0xfff0 /* index mask */ +#define RELFLG 0x0001 /* PC-relative flag. */ +#define RTYPE 0x000e /* Type mask. */ +#define RIDXMASK 0xfff0 /* Index mask. */ -#define RABS 0x00 /* absolute */ -#define RTEXT 0x02 /* text */ -#define RDATA 0x04 /* data */ -#define RBSS 0x06 /* bss */ -#define REXT 0x08 /* external */ +#define RABS 0x00 /* Absolute. */ +#define RTEXT 0x02 /* Text. */ +#define RDATA 0x04 /* Data. */ +#define RBSS 0x06 /* Bss. */ +#define REXT 0x08 /* External. */ #define RINDEX(x) (((x) & 0xfff0) >> 4) -static bfd_boolean aout_get_external_symbols PARAMS ((bfd *)); -static bfd_boolean translate_from_native_sym_flags - PARAMS ((bfd *, aout_symbol_type *)); -static bfd_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 *)); - -static int pdp11_aout_write_headers PARAMS ((bfd *, struct internal_exec *)); -void pdp11_aout_swap_reloc_out PARAMS ((bfd *, arelent *, bfd_byte *)); -void pdp11_aout_swap_reloc_in -PARAMS ((bfd *, bfd_byte *, arelent *, - bfd_size_type, asymbol **, bfd_size_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.
