* cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
files will eventually contain processor specific bits for bfd,
like strange relocation information and dis/assembly. So far only
the H8 has been even partially done. This work also ties in with
the change in handling architectures.
* aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
discover the architecture of the bfd. (sunos4_callback) calls the
function bfd_set_arch_mach rather than stuffing stuff directly
into the bfd. (sunos4_write_object_contents), changed names of
accessor functions.
* aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
setup the environment.
* archive.c: (bfd_slurp_coff_armap) coff archives always have the
headers in big endian format, regardless of the endianess of the
host or target.
* archures.c: totally changed. Now an architecture is represented
with a pointer to an info structure rather than an enumerated type
and a long. The old info is available as two elements in the
structure. Future enhancements to architecure support will
involve pointers to methods being placed into the info structure.
* bfd.c: changed the definition of the bfd structure for the new
architecture stuff.
* bout.c: (b_out_set_arch_mach) changed to use the new
architecture mechanism.
* coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
the new architecture mechanism.
* configure.in: added h8 stuff.
* ieee.c: too many changes to note. Now ieee files written with
bfd gas and ld can be read by gld and ieee only linkers and
simulators.
* libbfd.c, libbfd.h: changed prototype of bfd_write.
* newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
than fixing the structure directly.
* oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
than fixing the structure directly.
* opncls.c: (new_bfd) makes sure that bfd_init has been called
before opening a bfd.
* srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
rather than fixing the structure directly.
* targets.c: (target_vector) now by defining SELECT_VECS (perhaps
in the t/hmake file) a user can select which backends they want
linked with bfd without changing the source.
* init.c: new, looks after initializing modules.
* howto.c: for future use, will allow an application to work out
what cookie to use as a handle on a relcoatio howto.

DESCRIPTION
|
1991-12-01 01:39:12 +01:00
|
|
|
Each port of BFD to a different machine requries the creation
|
|
|
|
|
of a target back end. All the back end provides to the root
|
|
|
|
|
part of BFD is a structure containing pointers to functions
|
|
|
|
|
which perform certain low level operations on files. BFD
|
|
|
|
|
translates the applications's requests through a pointer into
|
|
|
|
|
calls to the back end routines.
|
|
|
|
|
|
|
|
|
|
When a file is opened with <<bfd_openr>>, its format and
|
|
|
|
|
target are unknown. BFD uses various mechanisms to determine
|
|
|
|
|
how to interpret the file. The operations performed are:
|
|
|
|
|
|
1993-11-05 20:51:52 +01:00
|
|
|
o Create a BFD by calling the internal routine
|
|
|
|
|
<<new_bfd>>, then call <<bfd_find_target>> with the
|
1991-12-01 01:39:12 +01:00
|
|
|
target string supplied to <<bfd_openr>> and the new BFD pointer.
|
|
|
|
|
|
|
|
|
|
o If a null target string was provided to <<bfd_find_target>>,
|
1993-11-05 20:51:52 +01:00
|
|
|
look up the environment variable <<GNUTARGET>> and use
|
1991-12-01 01:39:12 +01:00
|
|
|
that as the target string.
|
|
|
|
|
|
1993-11-17 21:31:32 +01:00
|
|
|
o If the target string is still <<NULL>>, or the target string is
|
1993-11-05 20:51:52 +01:00
|
|
|
<<default>>, then use the first item in the target vector
|
|
|
|
|
as the target type, and set <<target_defaulted>> in the BFD to
|
1992-09-26 04:20:05 +02:00
|
|
|
cause <<bfd_check_format>> to loop through all the targets.
|
|
|
|
|
@xref{bfd_target}. @xref{Formats}.
|
1991-12-01 01:39:12 +01:00
|
|
|
|
1993-11-05 20:51:52 +01:00
|
|
|
o Otherwise, inspect the elements in the target vector
|
1991-12-01 01:39:12 +01:00
|
|
|
one by one, until a match on target name is found. When found,
|
1993-11-05 20:51:52 +01:00
|
|
|
use it.
|
1991-12-01 01:39:12 +01:00
|
|
|
|
1993-11-05 20:51:52 +01:00
|
|
|
o Otherwise return the error <<invalid_target>> to
|
1991-12-01 01:39:12 +01:00
|
|
|
<<bfd_openr>>.
|
|
|
|
|
|
|
|
|
|
o <<bfd_openr>> attempts to open the file using
|
|
|
|
|
<<bfd_open_file>>, and returns the BFD.
|
|
|
|
|
|
|
|
|
|
Once the BFD has been opened and the target selected, the file
|
|
|
|
|
format may be determined. This is done by calling
|

DESCRIPTION
|
1991-12-01 01:39:12 +01:00
|
|
|
This structure contains everything that BFD knows about a
|
1993-11-05 20:51:52 +01:00
|
|
|
target. It includes things like its byte order, name, and which
|
|
|
|
|
routines to call to do various operations.
|
1991-07-04 18:52:56 +02:00
|
|
|
|
1991-12-01 01:39:12 +01:00
|
|
|
Every BFD points to a target structure with its <<xvec>>
|
|
|
|
|
member.
|
1991-07-04 18:52:56 +02:00
|
|
|
|
1993-11-05 20:51:52 +01:00
|
|
|
The macros below are used to dispatch to functions through the
|
|
|
|
|
<<bfd_target>> vector. They are used in a number of macros further
|
1991-12-01 01:39:12 +01:00
|
|
|
down in @file{bfd.h}, and are also used when calling various
|
1993-11-05 20:51:52 +01:00
|
|
|
routines by hand inside the BFD implementation. The @var{arglist}
|
1991-12-01 01:39:12 +01:00
|
|
|
argument must be parenthesized; it contains all the arguments
|
|
|
|
|
to the called function.

|
|
|
|
1992-06-16 14:04:03 +02:00
|
|
|
They make the documentation (more) unpleasant to read, so if
|
|
|
|
|
someone wants to fix this and not break the above, please do.

For operations which index on the BFD format:

1991-07-04 18:52:56 +02:00

This is the structure which defines the type of BFD this is. The
|
1991-12-01 01:39:12 +01:00
|
|
|
<<xvec>> member of the struct <<bfd>> itself points here. Each
|
|
|
|
|
module that implements access to a different target under BFD,
|
|
|
|
|
defines one of these.

FIXME, these names should be rationalised with the names of
|
|
|
|
|
the entry points which call them. Too bad we can't have one
|
|
|
|
|
macro to define them both!

Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
* cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
files will eventually contain processor specific bits for bfd,
like strange relocation information and dis/assembly. So far only
the H8 has been even partially done. This work also ties in with
the change in handling architectures.
* aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
discover the architecture of the bfd. (sunos4_callback) calls the
function bfd_set_arch_mach rather than stuffing stuff directly
into the bfd. (sunos4_write_object_contents), changed names of
accessor functions.
* aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
setup the environment.
* archive.c: (bfd_slurp_coff_armap) coff archives always have the
headers in big endian format, regardless of the endianess of the
host or target.
* archures.c: totally changed. Now an architecture is represented
with a pointer to an info structure rather than an enumerated type
and a long. The old info is available as two elements in the
structure. Future enhancements to architecure support will
involve pointers to methods being placed into the info structure.
* bfd.c: changed the definition of the bfd structure for the new
architecture stuff.
* bout.c: (b_out_set_arch_mach) changed to use the new
architecture mechanism.
* coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
the new architecture mechanism.
* configure.in: added h8 stuff.
* ieee.c: too many changes to note. Now ieee files written with
bfd gas and ld can be read by gld and ieee only linkers and
simulators.
* libbfd.c, libbfd.h: changed prototype of bfd_write.
* newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
than fixing the structure directly.
* oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
than fixing the structure directly.
* opncls.c: (new_bfd) makes sure that bfd_init has been called
before opening a bfd.
* srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
rather than fixing the structure directly.
* targets.c: (target_vector) now by defining SELECT_VECS (perhaps
in the t/hmake file) a user can select which backends they want
linked with bfd without changing the source.
* init.c: new, looks after initializing modules.
* howto.c: for future use, will allow an application to work out
what cookie to use as a handle on a relcoatio howto.

DESCRIPTION

|
|
|
Return a pointer to the transfer vector for the object target
|
1993-11-17 21:31:32 +01:00
|
|
|
named @var{target_name}. If @var{target_name} is <<NULL>>, choose the

|
|
|
|
one in the environment variable <<GNUTARGET>>; if that is null or not
|
1993-11-05 20:51:52 +01:00
|
|
|
defined, then choose the first entry in the target list.
|
1991-12-01 01:39:12 +01:00
|
|
|
Passing in the string "default" or setting the environment
|
|
|
|
|
variable to "default" will cause the first entry in the target
|
|
|
|
|
list to be returned, and "target_defaulted" will be set in the
|
|
|
|
|
BFD. This causes <<bfd_check_format>> to loop over all the
|
|
|
|
|
targets to find the one that matches the file being read.

cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
files will eventually contain processor specific bits for bfd,
like strange relocation information and dis/assembly. So far only
the H8 has been even partially done. This work also ties in with
the change in handling architectures.
* aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
discover the architecture of the bfd. (sunos4_callback) calls the
function bfd_set_arch_mach rather than stuffing stuff directly
into the bfd. (sunos4_write_object_contents), changed names of
accessor functions.
* aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
setup the environment.
* archive.c: (bfd_slurp_coff_armap) coff archives always have the
headers in big endian format, regardless of the endianess of the
host or target.
* archures.c: totally changed. Now an architecture is represented
with a pointer to an info structure rather than an enumerated type
and a long. The old info is available as two elements in the
structure. Future enhancements to architecure support will
involve pointers to methods being placed into the info structure.
* bfd.c: changed the definition of the bfd structure for the new
architecture stuff.
* bout.c: (b_out_set_arch_mach) changed to use the new
architecture mechanism.
* coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
the new architecture mechanism.
* configure.in: added h8 stuff.
* ieee.c: too many changes to note. Now ieee files written with
bfd gas and ld can be read by gld and ieee only linkers and
simulators.
* libbfd.c, libbfd.h: changed prototype of bfd_write.
* newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
than fixing the structure directly.
* oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
than fixing the structure directly.
* opncls.c: (new_bfd) makes sure that bfd_init has been called
before opening a bfd.
* srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
rather than fixing the structure directly.
* targets.c: (target_vector) now by defining SELECT_VECS (perhaps
in the t/hmake file) a user can select which backends they want
linked with bfd without changing the source.
* init.c: new, looks after initializing modules.
* howto.c: for future use, will allow an application to work out
what cookie to use as a handle on a relcoatio howto.
