2020-11-18Support SHF_GNU_RETAIN ELF section flagJozef Lawrynowicz1-0/+4
The SHF_GNU_RETAIN section flag is an extension to the GNU ELF OSABI. It is defined as follows: ========================================================= Section Attribute Flags +-------------------------------------+ | Name | Value | +-------------------------------------+ | SHF_GNU_RETAIN | 0x200000 (1 << 21) | +-------------------------------------+ SHF_GNU_RETAIN The link editor should not garbage collect the section. ========================================================= The .section directive accepts the "R" flag, which indicates SHF_GNU_RETAIN should be applied to the section. There is not a direct mapping of SHF_GNU_RETAIN to the BFD section flag SEC_KEEP. Keeping these flags distinct allows SHF_GNU_RETAIN sections to be explicitly removed by placing them in /DISCARD/. bfd/ChangeLog: * elf-bfd.h (enum elf_gnu_osabi): Add elf_gnu_osabi_retain. (struct elf_obj_tdata): Increase has_gnu_osabi to 4 bits. * elf.c (_bfd_elf_make_section_from_shdr): Set elf_gnu_osabi_retain for SHF_GNU_RETAIN. (_bfd_elf_final_write_processing): Report if SHF_GNU_RETAIN is not supported by the OSABI. Adjust error messages. * elflink.c (elf_link_input_bfd): Copy enabled has_gnu_osabi bits from input BFD to output BFD. (bfd_elf_gc_sections): gc_mark the section if SHF_GNU_RETAIN is set. binutils/ChangeLog: * NEWS: Announce SHF_GNU_RETAIN support. * readelf.c (get_elf_section_flags): Handle SHF_GNU_RETAIN. Recognize SHF_GNU_RETAIN and SHF_GNU_MBIND only for supported OSABIs. * testsuite/binutils-all/readelf.exp: Run new tests.

2020-01-09Add support for debuginfod to the binutils (disable by default, enabled via ↵Aaron Merey1-0/+9
a configure time option). debuginfod is a lightweight web service that indexes ELF/DWARF debugging resources by build-id and serves them over HTTP. This patch enables objdump and readelf to query debuginfod servers when they are otherwise not able to find separate debug files. Binutils can be built with debuginfod using the --with-debuginfod configure option. This requires that libdebuginfod be installed and found at configure time. debuginfod is packaged with elfutils, starting with version 0.178.

2019-05-28binutils: CTF support for objdump and readelfNick Alcock1-1/+4
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/ * objdump.c (ctf-api.h): New include. (dump_ctf_section_info): New variable.

2019-02-08binutils: Add new GNU format mode to `size` utilityAndrew Burgess1-0/+5
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.

2018-07-02Fix use of "command line X" in binutils docThomas Preud'homme1-17/+17
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/+8
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.
