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:
|
|
|
|
|
|
|
|
o First a BFD is created by calling the internal routine
|
|
|
|
<<new_bfd>>, then <<bfd_find_target>> is called with the
|
|
|
|
target string supplied to <<bfd_openr>> and the new BFD pointer.
|
|
|
|
|
|
|
|
o If a null target string was provided to <<bfd_find_target>>,
|
|
|
|
it looks up the environment variable <<GNUTARGET>> and uses
|
|
|
|
that as the target string.
|
|
|
|
|
|
|
|
o If the target string is still NULL, or the target string is
|
|
|
|
<<default>>, then the first item in the target vector is used
|
|
|
|
as the target type. @xref{bfd_target}.
|
|
|
|
|
|
|
|
o Otherwise, the elements in the target vector are inspected
|
|
|
|
one by one, until a match on target name is found. When found,
|
|
|
|
that is used.
|
|
|
|
|
|
|
|
o Otherwise the error <<invalid_target>> is returned to
|
|
|
|
<<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
|
|
|
|
<<bfd_check_format>> on the BFD with a suggested format. The
|
|
|
|
routine returns <<true>> when the application guesses right.

Entries for byte swapping for data. These are different to the other

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.

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

* 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

* init.c: new, looks after initializing modules.
* howto.c: for future use, will allow an application to work out

FUNCTION
|
|
|
|
bfd_find_target
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
Returns a pointer to the transfer vector for the object target
|
|
|
|
named target_name. If target_name is NULL, chooses the one in
|
|
|
|
the environment variable GNUTARGET; if that is null or not
|
|
|
|
defined thenthe first entry in the target list is chosen.
|
|
|
|
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-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.
