/* Objdump overview.
|
|
|
|
|
|
|
|
|
|
Objdump displays information about one or more object files, either on
|
|
|
|
|
their own, or inside libraries. It is commonly used as a disassembler,
|
|
|
|
|
but it can also display information about file headers, symbol tables,
|
|
|
|
|
relocations, debugging directives and more.
|
|
|
|
|
|
|
|
|
|
The flow of execution is as follows:
|
2015-08-12 13:42:37 +02:00
|
|
|
|
|
2003-09-03 10:26:52 +02:00
|
|
|
|
1. Command line arguments are checked for control switches and the
|
|
|
|
|
information to be displayed is selected.
|
2015-08-12 13:42:37 +02:00
|
|
|
|
|
2003-09-03 10:26:52 +02:00
|
|
|
|
2. Any remaining arguments are assumed to be object files, and they are
|
|
|
|
|
processed in order by display_bfd(). If the file is an archive each
|
|
|
|
|
of its elements is processed in turn.
|
2015-08-12 13:42:37 +02:00
|
|
|
|
|
2003-10-27 14:20:32 +01:00
|
|
|
|
3. The file's target architecture and binary file format are determined
|
2003-09-03 10:26:52 +02:00
|
|
|
|
by bfd_check_format(). If they are recognised, then dump_bfd() is
|
|
|
|
|
called.
|
|
|
|
|
|
2003-10-27 14:20:32 +01:00
|
|
|
|
4. dump_bfd() in turn calls separate functions to display the requested
|
|
|
|
|
item(s) of information(s). For example disassemble_data() is called if
|
2003-12-06 01:06:12 +01:00
|
|
|
|
a disassembly has been requested.
|
2003-09-03 10:26:52 +02:00
|
|
|
|
|
|
|
|
|
When disassembling the code loops through blocks of instructions bounded
|
2003-10-27 14:20:32 +01:00
|
|
|
|
by symbols, calling disassemble_bytes() on each block. The actual
|
2003-09-03 10:26:52 +02:00
|
|
|
|
disassembling is done by the libopcodes library, via a function pointer
|
|
|
|
|
supplied by the disassembler() function. */

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.

with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.

available.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.

with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

objdump_print_symname (abfd, inf, sym);
|
Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds

in gas processing.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of

[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)
