2022-07-25opcodes: add new sub-mnemonic disassembler styleAndrew Burgess1-0/+2
When adding libopcodes disassembler styling support for AArch64, it feels like the results would be improved by having a new sub-mnemonic style. This will be used in cases like: add w16, w7, w1, uxtb #2 ^^^^----- Here And: cinc w0, w1, ne ^^----- Here This commit just adds the new style, and prepares objdump to handle the style. A later commit will add AArch64 styling, and will actually make use of the style. As this style is currently unused, there should be no user visible changes after this commit.

2022-07-21PR29370, infinite loop in display_debug_abbrevAlan Modra1-13/+6
The PR29370 testcase is a fuzzed object file with multiple .trace_abbrev sections. Multiple .trace_abbrev or .debug_abbrev sections are not a violation of the DWARF standard. The DWARF5 standard even gives an example of multiple .debug_abbrev sections contained in groups. Caching and lookup of processed abbrevs thus needs to be done by section and offset rather than base and offset. (Why base anyway?) Or, since section contents are kept, by a pointer into the contents. PR 29370 * dwarf.c (struct abbrev_list): Replace abbrev_base and abbrev_offset with raw field. (find_abbrev_list_by_abbrev_offset): Delete. (find_abbrev_list_by_raw_abbrev): New function. (process_abbrev_set): Set list->raw and list->next.

2022-07-21binutils/dwarf.c: abbrev cachingAlan Modra1-98/+110
I'm inclined to think that abbrev caching is counter-productive. The time taken to search the list of abbrevs converted to internal form is non-zero, and it's easy to decode the raw abbrevs. It's especially silly to cache empty lists of decoded abbrevs (happens with zero padding in .debug_abbrev), or abbrevs as they are displayed when there is no further use of those abbrevs. This patch stops caching in those cases. * dwarf.c (record_abbrev_list_for_cu): Add free_list param. Put abbrevs on abbrev_lists here. (new_abbrev_list): Delete function. (process_abbrev_set): Return newly allocated list. Move abbrev base, offset and size checking to..

2022-07-19[AArch64] Support AArch64 MTE memory tag dumps in core filesLuis Machado1-0/+1
The Linux kernel can dump memory tag segments to a core file, one segment per mapped range. The format and documentation can be found in the Linux kernel tree [1]. The following patch adjusts bfd and binutils so they can handle this new segment type and display it accordingly. It also adds code required so GDB can properly read/dump core file data containing memory tags. Upon reading, each segment that contains memory tags gets mapped to a section named "memtag". These sections will be used by GDB to lookup the tag data. There can be multiple such sections with the same name, and they are not numbered to simplify GDB's handling and lookup. There is another patch for GDB that enables both reading and dumping of memory tag segments. Tested on aarch64-linux Ubuntu 20.04.

2022-07-09Regenerate with automake-1.15.1Alan Modra3-482/+304
Until we update the recommended versions of autoconf/automake, files should be regenerated with automake-1.15.1 and autoconf-2.69. That's not because we think those versions are golden, and newer versions are bad. It's simply because maintainers want to be able to update configury files without trouble, and if someone regenerates files with automake-1.16.5 then --enable-maintainer-mode builds will hit errors: checking that generated files are newer than configure... configure.ac:26: error: version mismatch. This is Automake 1.15.1, configure.ac:26: but the definition used by this AM_INIT_AUTOMAKE configure.ac:26: comes from Automake 1.16.5. You should recreate configure.ac:26: aclocal.m4 with aclocal and run automake again. WARNING: 'automake-1.15' is probably too old. Correcting this requires regenerating the files by hand.

2022-07-04objcopy: bfd_alloc orelocationAlan Modra3-24/+28
This fixes an inconsequential objcopy memory leak. I'd normally ignore reports of leaks like this one, that are merely one block or fewer per section processed, since objcopy soon exits and frees all memory. However I thought it worth providing support for allocating memory on a bfd objalloc in objcopy and other utils.

Commit 04f096fb9e25 ("Move the xc16x target to the obsolete list") moved the architecture from the "obsolete but still available" to the "obsolete / support removed" list in config.bfd, making the architecture impossible to enable (except maybe via "enable everything" options").

For clang compiled objects with dwarf-5, location list offset address dump under DW_AT_location is corrected, where DW_FORM_loclistx is used.
