2022-04-04objdump/opcodes: add syntax highlighting to disassembler outputAndrew Burgess3-32/+232
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.

2022-03-25libtool.m4: fix the NM="/nm/over/here -B/option/with/path" caseNick Alcock1-7/+13
My previous nm patch handled all cases but one -- if the user set NM in the environment to a path which contained an option, libtool's nm detection tries to run nm against a copy of nm with the options in it: e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle". This is unlikely to be desirable: in this case we should run "/usr/bin/nm --blargle /usr/bin/nm". Furthermore, as part of this nm has to detect when the passed-in $NM contains a path, and in that case avoid doing a path search itself. This too was thrown off if an option contained something that looked like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run "nm -B../prev-gcc nm" which rarely works well (and indeed it looks to see whether that nm exists, finds it doesn't, and wrongly concludes that nm -p or whatever does not work). Fix all of these by clipping all options (defined as everything including and after the first " -") before deciding whether nm contains a path (but not using the clipped value for anything else), and then removing all options from the path-modified nm before looking to see whether that nm existed. NM=my-nm now does a path search and runs e.g. /usr/bin/my-nm -B /usr/bin/my-nm NM=/usr/bin/my-nm now avoids a path search and runs e.g. /usr/bin/my-nm -B /usr/bin/my-nm NM="my-nm -p../wombat" now does a path search and runs e.g. /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search: ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm This seems to be all combinations, including those used by GCC bootstrap (which, before this commit, fails to bootstrap when configured --with-build-config=bootstrap-lto, because the lto plugin is now using --export-symbols-regex, which requires libtool to find a working nm, while also using -B../prev-gcc to point at the lto plugin associated with the GCC just built.) Regenerate all affected configure scripts. * libtool.m4 (LT_PATH_NM): Handle user-specified NM with options, including options containing paths.

2022-03-16binutils/readelf: build against msgpack, dump NT_AMDGPU_METADATA note contentsSimon Marchi7-19/+374
The AMDGPU HSA OS ABI (code object v3 and above) defines the NT_AMDGPU_METADATA ELF note [1]. The content is a msgpack object describing, among other things, the kernels present in the code object and how to call them. I think it would be useful for readelf to be able to display the content of those notes. msgpack is a structured format, a bit like JSON, except not text-based. It is therefore possible to dump the contents in human-readable form without knowledge of the specific layout of the note. Add configury to binutils to optionally check for the msgpack C library [2]. Add There is a new --with{,out}-msgpack configure flag, and the actual library lookup is done using pkg-config. If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks like: $ readelf --notes amdgpu-code-object Displaying notes found in: .note Owner Data size Description AMDGPU 0x0000040d NT_AMDGPU_METADATA (code object metadata) { "amdhsa.kernels": [ { ".args": [ { ".address_space": "global", ".name": "out.coerce", ".offset": 0, ".size": 8, ".value_kind": "global_buffer", }, <snip> If msgpack support is disabled, dump the contents as hex, as is done with notes that are not handled in a special way. This allows one to decode the contents manually (maybe using a command-line msgpack decoder) if really needed.

2022-02-03Support symbol+offset lookup in addr2lineAndi Kleen2-13/+80
The Linux kernel usually ouputs symbol+offset instead of plain code addresses these days, to avoid leaking ASLR secrets and to handle dynamically loaded modules. Converting those with addr2line is somewhat involved: it requires looking up the symbol first using nm and then manually compute the offset, and then pass it to addr2line. This patch implements the necessary steps directly in addr2line, by looking up the symbol (with demangling if needed) and computing the offset. It's possible that a symbol is ambigious with a hex number. In this case it uses the symbol lookup if the string contains a +. When it isn't ambigious the + is optional.

2022-01-29objcopy --only-keep-debugAlan Modra1-3/+3
From: Peilin Ye <peilin.ye@bytedance.com> objcopy's --only-keep-debug option has been broken for ELF files since commit 8c803a2dd7d3. 1. binutils/objcopy.c:setup_section() marks non-debug sections as SHT_NOBITS, then calls bfd_copy_private_section_data(); 2. If ISEC and OSEC share the same section flags, bfd/elf.c:_bfd_elf_init_private_section_data() restores OSEC's section type back to ISEC's section type, effectively undoing "make_nobits". * objcopy.c (setup_section): Act on make_nobits after calling bfd_copy_private_section_data.
