DESCRIPTION
|
2005-06-07 22:53:32 +00:00
|
|
|
|
Open the file @var{filename} with the target @var{target}.
|
|
|
|
|
Return a pointer to the created BFD. If @var{fd} is not -1,
|
|
|
|
|
then <<fdopen>> is used to open the file; otherwise, <<fopen>>
|
|
|
|
|
is used. @var{mode} is passed directly to <<fopen>> or
|
2013-01-10 20:03:55 +00:00
|
|
|
|
<<fdopen>>.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
|
|
|
|
Calls <<bfd_find_target>>, so @var{target} is interpreted as by
|
|
|
|
|
that function.
|
|
|
|
|
|
2005-06-09 07:30:19 +00:00
|
|
|
|
The new BFD is marked as cacheable iff @var{fd} is -1.
|
|
|
|
|
|
1999-05-03 07:29:11 +00:00
|
|
|
|
If <<NULL>> is returned then an error has occured. Possible errors
|
2002-10-06 09:03:06 +00:00
|
|
|
|
are <<bfd_error_no_memory>>, <<bfd_error_invalid_target>> or
|
|
|
|
|
<<system_call>> error.
|
2012-05-29 14:23:40 +00:00
|
|
|
|
|
|
|
|
|
On error, @var{fd} is always closed.
|
2014-01-02 12:14:37 +00:00
|
|
|
|
|
|
|
|
|
A copy of the @var{filename} argument is stored in the newly created
|
|
|
|
|
BFD. It can be accessed via the bfd_get_filename() macro.

DESCRIPTION
|
|
|
|
|
Open the file @var{filename} (using <<fopen>>) with the target
|
|
|
|
|
@var{target}. Return a pointer to the created BFD.
|
|
|
|
|
|
|
|
|
|
Calls <<bfd_find_target>>, so @var{target} is interpreted as by
|
|
|
|
|
that function.
|
|
|
|
|
|
|
|
|
|
If <<NULL>> is returned then an error has occured. Possible errors
|
|
|
|
|
are <<bfd_error_no_memory>>, <<bfd_error_invalid_target>> or
|
|
|
|
|
<<system_call>> error.
|
2014-01-02 12:14:37 +00:00

|
|
|
|
|
|
DESCRIPTION
|
2002-10-06 09:03:06 +00:00
|
|
|
|
<<bfd_fdopenr>> is to <<bfd_fopenr>> much like <<fdopen>> is to
|
|
|
|
|
<<fopen>>. It opens a BFD on a file already described by the
|
|
|
|
|
@var{fd} supplied.
|
|
|
|
|
|
|
|
|
|
When the file is later <<bfd_close>>d, the file descriptor will
|
|
|
|
|
be closed. If the caller desires that this file descriptor be
|
|
|
|
|
cached by BFD (opened as needed, closed as needed to free
|
|
|
|
|
descriptors for other opens), with the supplied @var{fd} used as
|
|
|
|
|
an initial file descriptor (but subject to closure at any time),
|
|
|
|
|
call bfd_set_cacheable(bfd, 1) on the returned BFD. The default
|
2003-11-30 18:40:41 +00:00
|
|
|
|
is to assume no caching; the file descriptor will remain open
|
2002-10-06 09:03:06 +00:00
|
|
|
|
until <<bfd_close>>, and will not be affected by BFD operations
|
|
|
|
|
on other files.
|
|
|
|
|
|
|
|
|
|
Possible errors are <<bfd_error_no_memory>>,
|
|
|
|
|
<<bfd_error_invalid_target>> and <<bfd_error_system_call>>.
|
2012-05-29 14:23:40 +00:00
|
|
|
|
|
|
|
|
|
On error, @var{fd} is closed.
|
2014-01-02 12:14:37 +00:00
|
|
|
|
|
|
|

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.

|
|
|
|
|
|
|
|
|
Create and return a BFD backed by a read-only @var{stream}.

|
|
The @var{stream} is created using @var{open_func}, accessed using
|
|
|
|
|
@var{pread_func} and destroyed using @var{close_func}.

|
DESCRIPTION
|
|
|
|
|
Create a BFD, associated with file @var{filename}, using the
|
|
|
|
|
file format @var{target}, and return a pointer to it.
|
|
|
|
|
|
|
|
|
|
Possible errors are <<bfd_error_system_call>>, <<bfd_error_no_memory>>,
|
|
|
|
|
<<bfd_error_invalid_target>>.
|
2014-01-02 12:14:37 +00:00
|
|
|
|
|
|
|
|
|
A copy of the @var{filename} argument is stored in the newly created
|
|
|
|
|
BFD. It can be accessed via the bfd_get_filename() macro.

|
|
|
|
Close a BFD. If the BFD was open for writing, then pending

|
|
operations are completed and the file written out and closed.
|
|

|
The file descriptor associated with the BFD is closed (even

SYNOPSIS

DESCRIPTION
|
|
|
|
|
Takes a BFD as created by <<bfd_create>> and
|
|
|
|
|
<<bfd_make_writable>> and converts it into one like as
|
|
|
|
|
returned by <<bfd_openr>>. It does this by writing the
|
|
|
|
|
contents out to the memory buffer, then reversing the
|
|
|
|
|
direction.

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.

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.

GNU Extension: separate debug-info files

|

2003-01-31 10:04:16 +00:00
|
|
|
|
The idea here is that a special section called .gnu_debuglink might be
|
|
|
|
|
embedded in a binary file, which indicates that some *other* file
|
|
|
|
|
contains the real debugging information. This special section contains a
|
|
|
|
|
filename and CRC32 checksum, which we read and resolve to another file,
|
|
|
|
|
if it exists.
|
|
|
|
|
|
|
|
|
|
This facilitates "optional" provision of debugging information, without
|
|
|
|
|
having to provide two complete copies of every binary object (with and
|
2013-05-29 14:58:35 +00:00
|
|
|
|
without debug symbols). */

Rename "_raw_size" to "rawsize".
(STD_SECTION): Adjust comments.
(bfd_set_section_size, bfd_get_section_contents): Use size.
(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

* section.c (struct sec): Rename "_cooked_size" to "size".
Rename "_raw_size" to "rawsize".
(STD_SECTION): Adjust comments.
(bfd_set_section_size, bfd_get_section_contents): Use size.
(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

bfd/
* section.c (struct sec): Rename "_cooked_size" to "size".
Rename "_raw_size" to "rawsize".
(STD_SECTION): Adjust comments.
(bfd_set_section_size, bfd_get_section_contents): Use size.
(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

bfd/
* section.c (struct sec): Rename "_cooked_size" to "size".
Rename "_raw_size" to "rawsize".
(STD_SECTION): Adjust comments.
(bfd_set_section_size, bfd_get_section_contents): Use size.
(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

fix PR symtab/15597
This patch fixes gdb PR symtab/15597.
The bug is that the .gnu_debugaltlink section includes the build-id of
the alt file, but gdb does not use it.
This patch fixes the problem by changing gdb to do what it ought to
always have done: verify the build id of the file found using the
filename in .gnu_debugaltlink; and if that does not match, try to find
the correct debug file using the build-id and debug-file-directory.
This patch touches BFD. Previously, gdb had its own code for parsing
.gnu_debugaltlink; I changed it to use the BFD functions after those
were introduced. However, the BFD functions are incorrect -- they
assume that .gnu_debugaltlink is formatted like .gnu_debuglink.
However, it it is not. Instead, it consists of a file name followed
by the build-id -- no alignment, and the build-id is not a CRC.
Fixing this properly is a bit of a pain. But, because
separate_alt_debug_file_exists just has a FIXME for the build-id case,
I did not fix it properly. Instead I introduced a hack. This leaves
BFD working just as well as it did before my patch.
I'm willing to do something better here but I could use some guidance
as to what. It seems that the build-id code in BFD is largely punted
on.
FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of
BFD itself.
I moved the build-id logic out of elfread.c and into a new file.
This seemed cleanest to me.
Writing a test case was a bit of a pain. I added a couple new
features to the DWARF assembler to handle this.
Built and regtested on x86-64 Fedora 18.

fix PR symtab/15597
This patch fixes gdb PR symtab/15597.
The bug is that the .gnu_debugaltlink section includes the build-id of
the alt file, but gdb does not use it.
This patch fixes the problem by changing gdb to do what it ought to
always have done: verify the build id of the file found using the
filename in .gnu_debugaltlink; and if that does not match, try to find
the correct debug file using the build-id and debug-file-directory.
This patch touches BFD. Previously, gdb had its own code for parsing
.gnu_debugaltlink; I changed it to use the BFD functions after those
were introduced. However, the BFD functions are incorrect -- they
assume that .gnu_debugaltlink is formatted like .gnu_debuglink.
However, it it is not. Instead, it consists of a file name followed
by the build-id -- no alignment, and the build-id is not a CRC.
Fixing this properly is a bit of a pain. But, because
separate_alt_debug_file_exists just has a FIXME for the build-id case,
I did not fix it properly. Instead I introduced a hack. This leaves
BFD working just as well as it did before my patch.
I'm willing to do something better here but I could use some guidance
as to what. It seems that the build-id code in BFD is largely punted
on.
FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of
BFD itself.
I moved the build-id logic out of elfread.c and into a new file.
This seemed cleanest to me.
Writing a test case was a bit of a pain. I added a couple new
features to the DWARF assembler to handle this.
Built and regtested on x86-64 Fedora 18.

* opncls.c (bfd_get_alt_debug_link_info): Add buildid_len
parameter. Change type of buildid_out. Update.

|
|
|
Searches @var{abfd} for a section called @var{section_name} which
|
|
|
|
|
is expected to contain a reference to a file containing separate
|
|
|
|
|
debugging information. The function scans various locations in
|
|
|
|
|
the filesystem, including the file tree rooted at
|
|
|
|
|
@var{debug_file_directory}, and returns the first matching
|
|
|
|
|
filename that it finds. If @var{check_crc} is TRUE then the
|
|
|
|
|
contents of the file must also match the CRC value contained in
|
|
|
|
|
@var{section_name}. Returns NULL if no valid file could be found.

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Takes a BFD and searches it for a .gnu_debuglink section. If this
|
2004-01-21 11:17:53 +00:00
|
|
|
|
section is found, it examines the section for the name and checksum
|
|
|
|
|
of a '.debug' file containing auxiliary debugging information. It
|
|
|
|
|
then searches the filesystem for this .debug file in some standard
|
2003-01-31 10:04:16 +00:00
|
|
|
|
locations, including the directory tree rooted at @var{dir}, and if
|
2004-01-21 11:17:53 +00:00
|
|
|
|
found returns the full filename.
|
|
|
|
|
|
|
|
|
|
If @var{dir} is NULL, it will search a default path configured into
|
|
|
|
|
libbfd at build time. [XXX this feature is not currently
|
|
|
|
|
implemented].

fix PR symtab/15597
This patch fixes gdb PR symtab/15597.
The bug is that the .gnu_debugaltlink section includes the build-id of
the alt file, but gdb does not use it.
This patch fixes the problem by changing gdb to do what it ought to
always have done: verify the build id of the file found using the
filename in .gnu_debugaltlink; and if that does not match, try to find
the correct debug file using the build-id and debug-file-directory.
This patch touches BFD. Previously, gdb had its own code for parsing
.gnu_debugaltlink; I changed it to use the BFD functions after those
were introduced. However, the BFD functions are incorrect -- they
assume that .gnu_debugaltlink is formatted like .gnu_debuglink.
However, it it is not. Instead, it consists of a file name followed
by the build-id -- no alignment, and the build-id is not a CRC.
Fixing this properly is a bit of a pain. But, because
separate_alt_debug_file_exists just has a FIXME for the build-id case,
I did not fix it properly. Instead I introduced a hack. This leaves
BFD working just as well as it did before my patch.
I'm willing to do something better here but I could use some guidance
as to what. It seems that the build-id code in BFD is largely punted
on.
FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of
BFD itself.
I moved the build-id logic out of elfread.c and into a new file.
This seemed cleanest to me.
Writing a test case was a bit of a pain. I added a couple new
features to the DWARF assembler to handle this.
Built and regtested on x86-64 Fedora 18.
* bfd-in2.h: Rebuild.
* opncls.c (bfd_get_alt_debug_link_info): Add buildid_len
parameter. Change type of buildid_out. Update.
