2019-05-28binutils: CTF support for objdump and readelfNick Alcock1-0/+19
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.

2019-02-08binutils: Add new GNU format mode to `size` utilityAndrew Burgess1-4/+25
The size tool currently defaults to berkeley format output. However, this output format has a weird quirk, read-only data is counted against the text sections, not the data sections. The code offers no real explanation for why this is, but I'm reluctant to change it for two reasons, first, I'm assuming it probably makes sense in some case that I'm not thinking of (maybe a target where sections are not marked executable, and so there's no distinction between read-only data and code), and second, the code has been this way for at least 20 years, I worry that changing things now might cause more confusion than it solves. This commit then introduces a new output format for the size tool, this new format displays the results in a similar manor to the berkeley format, but counts read-only data in the data column, and only executable sections are counted in the text column. Given that this is a brand new output format I've gone ahead and simplified things a little, while the berkeley format displays the total twice, once in decimal and once in hex, the new display format just displays the total in decimal. Of course, there's still the '--radix' option which can be used to display all the results in hexadecimal or octal. I've called the new format 'gnu', so '--format=gnu' or '-G' are used to access it. binutils/ChangeLog: * size.c (berkeley_format): Delete. (enum output_format): New enum. (selected_output_format): New variable. (usage): Update to mention GNU format. (main): Update to extract options, and select format as needed. Handle GNU format where needed.

2018-10-11Prevent the --keep-global-symbol and --globalize-symbol options from being ↵Nick Clifton1-4/+9
used together. This is the result of an email thread starting here: https://sourceware.org/ml/binutils/2018-09/msg00031.html The main point of the thread is this observation: * Supposing we had an object file with two globals, SomeGlobal and SomeOtherGlobal, if one were to do "--globalize-symbol SomeGlobal --keep-global-symbol SomeOtherGlobal", you might expect that both SomeGlobal and SomeOtherGlobal are global in the output file... but it isn't. Because --keep-global-symbol is set and doesn't include SomeGlobal, SomeGlobal will be demoted to a local symbol. And because the check to see if we should apply the --globalize-symbol flag checks "flags" (the original flag set), and not "sym->flags", it decides not to do anything, so SomeGlobal remains a local symbol. Although this is a weird edge case, should this be changed so that --keep-global-symbol implicitly keeps anything also specified via --globalize-symbol? (The code seems technically correct with respect to the documentation, but IMO the behavior is counter-intuitive). binutils* objcopy.c (copy_main): Issue a fata error if the --keep-global-symbol(s) and the --globalize-symbol(s) options are used together. * doc/binutils.texi: Document that the two options are incompatible. * testsuite/binutils-all/copy-5.d: New test. * testsuite/binutils-all/objcopy.exp: Run the new test.
2018-09-10PR23611, objcopy is not removing executable relocatable sectionsAlan Modra1-5/+8
BFD handles ELF relocation sections in an executable differently to relocation sections in a relocatable object. For a relocatable object, BFD carries the relocations as data associated with the section to which they apply; The relocation section doesn't appear as a separate section. For an executable, dynamic relocation sections do appear as separate sections. This means that objcopy needs to use different strategies when dealing with relocations. When --remove-relocations was added to objcopy with commit d3e5f6c8f1e, objcopy lost the ability to remove dynamic relocation sections such as .rela.plt from executables using the option "--remove-section=.rela.plt". This patch reinstates that functionality. I thought it best to keep --remove-relocations as is, rather than extending to handle dynamic relocations as per the patch in the PR, because executables linked with --emit-relocs may have both dynamic and non-dynamic relocations. In that case --remove-relocataions=* is useful to remove all the non-dynamic relocations. PR binutils/23611 * objcopy.c (handle_remove_section_option): Consider .rela and .rel sections for stripping directly as well as attached to the associated section they relocate. * doc/binutils.texi (remove-relocations): Specify that this option removes non-dynamic relocation sections. * testsuite/binutils-all/objcopy.exp (objcopy_remove_relocations_from_executable): New test.
2018-07-02Fix use of "command line X" in binutils docThomas Preud'homme1-19/+19
Binutils documentation uses a mix of spelling for the compound word "command-line X". According to [1]: "Sometimes compound words are written separately (nail polish), sometimes with a hyphen (short-sighted) and sometimes as one word (eyelashes). Often new compounds are written as two separate words and, as they become more familiar, they are either connected with a hyphen (-) or made into one word." I think command-line X is common enough in our industry that the two workds command and line should be connected. Since command-line is more common than commandline, I propose to update binutils documentation to consistently use "command-line" when this is used as an adjective to a noun (eg. command-line argument, command-line switch, command-line option and command-line flag). I've left occurences of "the command line" as is. I've also left gdb, sim and readline alone and have only touched public documentation (texi and NEWS files).

2018-05-15Allow non-fatal errors to be emitted and for disassembly notes be placed on ↵Tamar Christina1-0/+5
AArch64 This patch adds a new platform option "notes" that can be used to indicate if disassembly notes should be placed in the disassembly as comments. These notes can contain information about a failing constraint such as reading from a write-only register. The disassembly will not be blocked because of this but -M notes will emit a comment saying that the operation is not allowed. For assembly this patch adds a new non-fatal status for errors. This is essentially a warning. The reason for not creating an actual warning type is that this causes the interaction between the ordering of warnings and errors to be problematic. Currently the error buffer is almost always filled because of the way operands are matched during assembly. An earlier template may have put an error there that would only be displayed if no other template matches or generates a higher priority error. But by definition a warning is lower priority than a warning, so the error (which is incorrect if another template matched) will supersede the warning. By treating warnings as errors and only later relaxing the severity this relationship keeps working and the existing reporting infrastructure can be re-used. binutils/ PR binutils/21446 * doc/binutils.texi (-M): Document AArch64 options. * NEWS: Document notes and warnings. gas/ PR binutils/21446 * config/tc-aarch64.c (print_operands): Indicate no notes.

2017-11-15Add support to readelf and objdump for following links to separate debug ↵Nick Clifton1-81/+10
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).

2017-05-30[ARC] Allow CPU to be enforced via disassemble_info optionsAnton Kolesov1-0/+8
Currently print_insn_arc relies on BFD mach and ELF private headers to distinguish between various ARC architectures. Sometimes those values are not correct or available, mainly in the case of debugging targets without and ELF file available. Changing a BFD mach is not a problem for the debugger, because this is a generic BFD field, and GDB, for example, already sets it according to information provided in XML target description or specified via GDB 'set arch' command. However, things are more complicated for ELF private headers, since it requires existing of an actual ELF file. To workaround this problem this patch allows CPU model to be specified via disassemble info options. If CPU is specified in options, then it will take a higher precedence than whatever might be specified in ELF file. This is mostly needed for ARC EM and ARC HS, because they have the same "architecture" (mach) ARCv2 and differ in their private ELF headers. Other ARC architectures can be distinguished between each other purely via "mach" field. Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid ARC CPU name as supported by GAS. Note that this creates a seeming redundancy with objdump -m/--architecture option, however -mEM and -mHS still result in "ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual effect on disassembler. opcodes/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * arc-dis.c (enforced_isa_mask): Declare.

2016-07-14objcopy/strip: Add option --remove-relocations=SECTIONPATTERNAndrew Burgess1-0/+58
The objcopy and strip tools make use of the bfd library to manipulate the state of the input file (to produce an output file). Within the input file (for ELF at least), relocations are held within a section, and so, if the user wanted to remove the relocations, but keep the section to which the relocations would have been applied, it is tempting to think that specifying the name of a relocation section to objcopy's --remove-section option might do what you want, for example: objcopy --remove-section=.rela.text input.elf output.elf However, this does not work. The reason is that when the input file is loaded, relocations are not managed as sections, but are, instead, loaded as data associated with the section to which the relocations would be applied. In our example above the relocations in '.rela.text' are held as data on the section '.text' once 'input.elf' is loaded. One task that objcopy and strip do is copy the relocations from the input file to the output file if the section is also being copied from the input file to the output file. This commit adds a new command line option for objcopy and strip, --remove-relocations, which can be used to remove the relocations, while keeping the section that the relocations would have been applied to, for example: objcopy --remove-relocations=.text input.elf output.elf in this case the section '.text' will appear in both 'input.elf' and 'output.elf', but any relocations in 'input.elf' that apply to '.text' will not be present in 'output.elf'. I have also added a special case to the handling of --remove-section that spots if a user tries to remove a relocation section (currently this is done by spotting the '.rela.' or '.rel.' prefix) and forwards the request to --remove-relocations. As with --remove-section and --only-section the --remove-relocations option supports the '!' prefix on the section-patterns it takes to allow for sections to be specifically not matched. There are tests for all the new functionality. binutils/ChangeLog: * doc/binutils.texi (objcopy): Document 'remove-relocations'.

2016-07-14objcopy/strip: Allow section patterns starting with '!'.Andrew Burgess1-0/+36
For symbol matching, prefixing a pattern with '!' will indicate a non-matching pattern, however, this is not the case for section patterns. As a result it is not possible to say "apply this action to all sections except ...".
