2022-09-13objdump: '-S' should trigger search for separate debuginfo.Aaron Merey1-2/+3
Add with_source_code to the command line options that trigger might_need_separate_debug_info and dump_any_debugging. This helps 'objdump -S' download missing files via debuginfod without the need for specifying extra command line options like '-L'.
2022-09-06Add debuginfod support for objdump -SAaron Merey1-41/+211
Currently objdump -S is not able to make use files downloaded from debuginfod. This is due to bfd_find_nearest_line_discriminator being unable to locate any separate debuginfo files in the debuginfod cache. Additionally objdump lacked a call to debuginfod_find_source in order to download missing source files. Fix this by using bfd_find_nearest_line_with_alt instead of bfd_find_nearest_line_discriminator. Also add a call to debuginfod_find_source in order to download missing source files.

2022-08-13Make dwarf_vma uint64_tAlan Modra1-1/+1
This replaces dwarf_vma, dwarf_size_type and dwarf_signed_vma with uint64_t and int64_t everywhere. The patch also gets rid of DWARF_VMA_FMT since we can't use that with uint64_t, and all of the configure support for deciding the flavour of HOST_WIDEST_INT. dwarf_vmatoa also disappears, replacing most uses with one of PRIx64, PRId64 or PRIu64. Printing of size_t and ptrdiff_t values now use %z and %t rather than by casting to unsigned long. Also, most warning messages that used 0x%lx or similar now use %#lx and a few that didn't print the 0x hex prefix now also use %#. The patch doesn't change normal readelf output, except in odd cases where values previously might have been truncated.

2022-04-04objdump/opcodes: add syntax highlighting to disassembler outputAndrew Burgess1-32/+217
This commit adds the _option_ of having disassembler output syntax highlighted in objdump. This option is _off_ by default. The new command line options are: --disassembler-color=off # The default. --disassembler-color=color --disassembler-color=extended-color I have implemented two colour modes, using the same option names as we use of --visualize-jumps, a basic 8-color mode ("color"), and an extended 8bit color mode ("extended-color"). The syntax highlighting requires that each targets disassembler be updated; each time the disassembler produces some output we now pass through an additional parameter indicating what style should be applied to the text. As updating all target disassemblers is a large task, the old API is maintained. And so, a user of the disassembler (i.e. objdump, gdb) must provide two functions, the current non-styled print function, and a new, styled print function. I don't currently have a plan for converting every single target disassembler, my hope is that interested folk will update the disassemblers they are interested in. But it is possible some might never get updated. In this initial series I intend to convert the RISC-V disassembler completely, and also do a partial conversion of the x86 disassembler. Hopefully having the x86 disassembler at least partial converted will allow more people to try this out easily and provide feedback. In this commit I have focused on objdump. The changes to GDB at this point are the bare minimum required to get things compiling, GDB makes no use of the styling information to provide any colors, that will come later, if this commit is accepted. This first commit in the series doesn't convert any target disassemblers at all (the next two commits will update some targets), so after this commit, the only color you will see in the disassembler output, is that produced from objdump itself, e.g. from objdump_print_addr_with_sym, where we print an address and a symbol name, these are now printed with styling information, and so will have colors applied (if the option is on). Finally, my ability to pick "good" colors is ... well, terrible. I'm in no way committed to the colors I've picked here, so I encourage people to suggest new colors, or wait for this commit to land, and then patch the choice of colors. I do have an idea about using possibly an environment variable to allow the objdump colors to be customised, but I haven't done anything like that in this commit, the color choices are just fixed in the code for now. binutils/ChangeLog: * NEWS: Mention new feature. * doc/binutils.texi (objdump): Describe --disassembler-color option. * objdump.c (disassembler_color): New global.

binutils/NEWS says of the change in --process-links semantics: If other debug section display options are also enabled (eg --debug-dump=info) then the contents of matching sections in both the main file and the separate debuginfo file *will* be displayed.

ld by default (and always, unless adjusted with a hand-rolled linker script) emits deduplicated CTF into the .ctf section.

2021-10-25binutils: make objdump/readelf --ctf-parent actually usefulNick Alcock1-49/+28
This option has been present since the very early days of the development of libctf as part of binutils, and it shows. Back in the earliest days, I thought we might handle ambiguous types by introducing new ELF sections on the fly named things like .ctf.foo.c for ambiguous types found only in foo.c, etc. This turned out to be a terrible idea, so we moved to using a CTF archive in the .ctf section which contained all the CTF dictionaries -- but the --ctf-parent option in objdump and readelf was never adjusted, and lingered as a mechanism to specify CTF parent dictionaries in sections other than .ctf, even though the linker has no way to produce parent dictionaries in different sections from their children, libctf's ctf_open can't handle such split-up parent/child dicts, and they are never found in the wild, emitted by GNU ld or by any known third-party linking tool. Meanwhile, the actually-useful ctf_link feature (albeit not used by ld) which lets you remap the names of CTF archive members (so you can end up with a parent archive member named something other than ".ctf", still contained with all its children in a single .ctf section) had no support in objdump or readelf: there was no way to tell them that these members were parents, so all the types in the associated child dicts always appeared corrupted, referencing nonexistent types from a parent objdump couldn't find. So adjust --ctf-parent so that rather than taking a section name it takes a member name instead (if not specified, the name is ".ctf", which is what GNU ld emits). Because the option was always useless before now, this is expected to have no backward-compatibility implications. As part of this, we have to slightly adjust the code which skips the archive member name if redundant: right now it skips it if it's ".ctf", on the assumption that this name will almost always be at the start of the objdump output and thus we'll end up with a shared dump and then smaller, headed dumps for the per-TU child dicts; but if the parent name has been changed, that won't be true any more. So change the rules to "members named .ctf which appear first in the first have their member name skipped". Since we now need to count members, move from ctf_archive_iter (for which passing in extra parameters requires defining a new struct and is clumsy) to ctf_archive_next, allowing us to just *call* dump_ctf_archive_member and maintain a member count in the obvious way. In the process we fix a tiny difference between readelf and objdump: if a ctf_dump ever failed, readelf skipped every later member, while objdump tried to keep going as much as it could. For a dumping tool the former is clearly preferable. binutils/ChangeLog 2021-10-25 Nick Alcock <nick.alcock@oracle.com> * objdump.c (usage): --ctf-parent now takes a name, not a section. (dump_ctf): Don't open a separate section; use the parent_name in ctf_dict_open instead. Use ctf_archive_next, not ctf_archive_iter, so we can pass down a member count. (dump_ctf_archive_member): Add the member count; don't return anything. Import parents into children no matter what the parent's name, while still avoiding displaying the header for the common parent name of ".ctf". * readelf.c (usage): Adjust similarly.

2021-03-29TRUE/FALSE simplificationAlan Modra1-1/+1
There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value. It's probably even a good idea to not rely on implicit conversion if bfd_boolean were _Bool. bfd/ * aoutx.h (aout_link_write_symbols): Don't cast boolean expression to bfd_boolean. * elf32-or1k.c (or1k_set_got_and_rela_sizes): Dont compare booleans against FALSE. * elf32-arc.c (name_for_global_symbol): Don't compare boolean to TRUE.
