DESCRIPTION
|
|
|
|
|
An archive (or library) is just another BFD. It has a symbol
|
|
|
|
|
table, although there's not much a user program will do with it.
|
|
|
|
|
|
|
|
|
|
The big difference between an archive BFD and an ordinary BFD
|
|
|
|
|
is that the archive doesn't have sections. Instead it has a
|
|
|
|
|
chain of BFDs that are considered its contents. These BFDs can
|
|
|
|
|
be manipulated like any other. The BFDs contained in an
|
|
|
|
|
archive opened for reading will all be opened for reading. You
|
|
|
|
|
may put either input or output BFDs into an archive opened for
|
|
|
|
|
output; they will be handled correctly when the archive is closed.
|
|
|
|
|
|
|
|
|
|
Use <<bfd_openr_next_archived_file>> to step through
|
|
|
|
|
the contents of an archive opened for input. You don't
|
|
|
|
|
have to read the entire archive if you don't want
|
|
|
|
|
to! Read it until you find what you want.
|
|
|
|
|
|
2012-08-09 08:25:53 +02:00
|
|
|
|
A BFD returned by <<bfd_openr_next_archived_file>> can be
|
|
|
|
|
closed manually with <<bfd_close>>. If you do not close it,
|
|
|
|
|
then a second iteration through the members of an archive may
|
|
|
|
|
return the same BFD. If you close the archive BFD, then all
|
|
|
|
|
the member BFDs will automatically be closed as well.
|
|
|
|
|
|
1999-05-03 09:29:11 +02:00
|
|
|
|
Archive contents of output BFDs are chained through the
|
2012-08-09 08:25:53 +02:00
|
|
|
|
<<archive_next>> pointer in a BFD. The first one is findable
|
|
|
|
|
through the <<archive_head>> slot of the archive. Set it with
|
|
|
|
|
<<bfd_set_archive_head>> (q.v.). A given BFD may be in only
|
|
|
|
|
one open output archive at a time.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
As expected, the BFD archive code is more general than the
|
|
|
|
|
archive code of any given environment. BFD archives may
|
|
|
|
|
contain files of different formats (e.g., a.out and coff) and
|
|
|
|
|
even different architectures. You may even place archives
|
|
|
|
|
recursively into archives!
|
|
|
|
|
|
|
|
|
|
This can cause unexpected confusion, since some archive
|
|
|
|
|
formats are more expressive than others. For instance, Intel
|
|
|
|
|
COFF archives can preserve long filenames; SunOS a.out archives
|
|
|
|
|
cannot. If you move a file from the first to the second
|
|
|
|
|
format and back again, the filename may be truncated.
|
|
|
|
|
Likewise, different a.out environments have different
|
|
|
|
|
conventions as to how they truncate filenames, whether they
|
|
|
|
|
preserve directory names in filenames, etc. When
|
|
|
|
|
interoperating with native tools, be sure your files are
|
|
|
|
|
homogeneous.
|
|
|
|
|
|
|
|
|
|
Beware: most of these formats do not react well to the
|
|
|
|
|
presence of spaces in filenames. We do the best we can, but
|
|
|
|
|
can't always handle this case due to restrictions in the format of
|
|
|
|
|
archives. Many Unix utilities are braindead in regards to
|
|
|
|
|
spaces and such in filenames anyway, so this shouldn't be much
|
|
|
|
|
of a restriction.
|
|
|
|
|
|
|
|
|
|
Archives are supported in BFD in <<archive.c>>.

|

/* Some formats provide a way to cram a long filename into the short
|
|
|
|
|
(16 chars) space provided by a BSD archive. The trick is: make a
|
|
|
|
|
special "file" in the front of the archive, sort of like the SYMDEF
|
|
|
|
|
entry. If the filename is too long to fit, put it in the extended
|
|
|
|
|
name table, and use its index as the filename. To prevent
|
|
|
|
|
confusion prepend the index with a space. This means you can't
|
|
|
|
|
have filenames that start with a space, but then again, many Unix
|
|
|
|
|
utilities can't handle that anyway.
|
|
|
|
|
|
|
|
|
|
This scheme unfortunately requires that you stand on your head in
|
|
|
|
|
order to write an archive since you need to put a magic file at the
|
|
|
|
|
front, and need to touch every entry to do so. C'est la vie.
|
|
|
|
|
|
|
|
|
|
We support two variants of this idea:
|
|
|
|
|
The SVR4 format (extended name table is named "//"),
|
|
|
|
|
and an extended pseudo-BSD variant (extended name table is named
|
|
|
|
|
"ARFILENAMES/"). The origin of the latter format is uncertain.
|
|
|
|
|
|
|
|
|
|
BSD 4.4 uses a third scheme: It writes a long filename
|
|
|
|
|
directly after the header. This allows 'ar q' to work.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

|
|
|
DESCRIPTION
|
|
|
|
|
Step through archive @var{abfd}'s symbol table (if it
|
|
|
|
|
has one). Successively update @var{sym} with the next symbol's
|
|
|
|
|
information, returning that symbol's (internal) index into the
|
|
|
|
|
symbol table.
|
|
|
|
|
|
|
|
|
|
Supply <<BFD_NO_MORE_SYMBOLS>> as the @var{previous} entry to get
|
|
|
|
|
the first one; returns <<BFD_NO_MORE_SYMBOLS>> when you've already
|
|
|
|
|
got the last one.
|
|
|
|
|
|
|
|
|
|
A <<carsym>> is a canonical archive symbol. The only
|
|
|
|
|
user-visible element is its name, a null-terminated string.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

DESCRIPTION
|
|
|
|
|
Provided a BFD, @var{archive}, containing an archive and NULL, open
|
|
|
|
|
an input BFD on the first contained element and returns that.
|
|
|
|
|
Subsequent calls should pass
|
|
|
|
|
the archive and the previous return value to return a created
|
|
|
|
|
BFD to the next contained element. NULL is returned when there
|
|
|
|
|
are no more.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if

or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and

o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.
