Alan Modra	0a3137ce4c	objdump -D of bss sections and -s with -j There is some inconsistency between the behaviour of objdump -D and objdump -s, both supposedly operating on all sections by default. objdump -s ignores bss sections, while objdump -D dissassembles the zeros. Fix this by making objdump -D ignore bss sections too. Furthermore, "objdump -s -j .bss" doesn't dump .bss as it should, since the user is specifically asking to look at all those zeros. This change does find some tests that used objdump -D with expected output in bss-style sections. I've updated all the msp430 tests that just wanted to find a non-empty section to look at section headers instead, making the tests slightly more stringent. The ppc xcoff and spu tests are fixed by adding -j options to objdump, which makes the tests somewhat more lenient. binutils/ * objdump.c (disassemble_section): Ignore sections without contents, unless overridden by -j.

Alan Modra	61a457e5da	e200 LSP support It has bothered me for a long time that we have disabled LSP (and SPE) tests. Also the LSP test comment indicating there is something wrong with get_powerpc_dialect. I don't think there is. Decoding of a VLE instruction depends on whether the processor is in VLE mode (some processors support both VLE and standard PPC) which we flag per section with SHF_PPC_VLE for decoding when disassembling. Background: Some versions of powerpc e200 have "Lightweight Signal Processing" support, examples being e200z215 and e200z425. As far as I can tell, LSP and SPE are mutually exclusive. This seems to be borne out by insn encoding, for example LSP "zvaddih" and SPE "evaddw" have the same encoding. So none of the processor descriptions in ppc_opts ought to have both PPC_OPCODE_LSP and PPC_OPCODE_SPE/2, if we want disassembly to work. I also could not find anything to suggest that the LSP insns are enabled only in VLE mode, which means the LSP insns should not be in vle_opcodes. Fix all this by moving the LSP insns to their own table, and add a new e200z2 cpu entry with LSP support, removing LSP from -me200z4 and from -mvle. (Yes, I know, as I said above some of the e200z4 processors have LSP. Others have SPE. It's hard to choose good options. Think of z2 as meaning earlier, z4 as later.)

Andrew Burgess	60a3da00bd	objdump/opcodes: add syntax highlighting to disassembler output 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.

Andi Kleen	fd3c53675c	Support symbol+offset lookup in addr2line 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.	5 years ago

Nick Alcock	10909ea819	binutils, ld: make objdump --ctf's parameter optional ld by default (and always, unless adjusted with a hand-rolled linker script) emits deduplicated CTF into the .ctf section. But viewing it needs you to explicitly tell objdump this: it doesn't default its argument, even though what you always end up typing is --ctf=.ctf. This is annoying, so make the argument optional. binutils/ChangeLog 2021-10-25 Nick Alcock <nick.alcock@oracle.com> * objdump.c (usage): --ctf now has an optional argument.

Nick Alcock	80b56fad5c	binutils: make objdump/readelf --ctf-parent actually useful 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. (dump_section_as_ctf): Likewise. (dump_ctf_archive_member): Likewise. Never stop iterating over archive members, even if ctf_dump of one member fails. * doc/ctf.options.texi: Adjust.	5 years ago
