2022-06-29opcodes/aarch64: split off creation of comment text in disassemblerAndrew Burgess1-1/+1
The function aarch64_print_operand (aarch64-opc.c) is responsible for converting an instruction operand into the textual representation of that operand. In some cases, a comment is included in the operand representation, though this (currently) only happens for the last operand of the instruction. In a future commit I would like to enable the new libopcodes styling for AArch64, this will allow objdump and GDB[1] to syntax highlight the disassembler output, however, having operands and comments combined in a single string like this makes such styling harder. In this commit, I propose to extend aarch64_print_operand to take a second buffer. Any comments for the instruction are written into this extra buffer. The two callers of aarch64_print_operand are then updated to pass an extra buffer, and print any resulting comment. In this commit no styling is added, that will come later. However, I have adjusted the output slightly. Before this commit some comments would be separated from the instruction operands with a tab character, while in other cases the comment was separated with two single spaces. After this commit I use a single tab character in all cases. This means a few test cases needed updated. If people would prefer me to move everyone to use the two spaces, then just let me know. Or maybe there was a good reason why we used a mix of styles, I could probably figure out a way to maintain the old output exactly if that is critical. Other than that, there should be no user visible changes after this commit.

2022-06-27drop XC16x bitsJan Beulich1-40/+0
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"). Note that I didn't touch */po/*.po{,t} on the assumption that these would be updated by some (half)automatic means.
2022-06-22RISC-V: Use single h extension to control hypervisor CSRs and instructions.Nelson Chu2-25/+26
According to the picture 28.1 in the current ISA spec, h is no larger the multi-letter extension, it is a single extension after v. Therefore, this patch fix the implementation, and use the single h to control hypervisor CSRs and instructions, which we promised to do before. bfd/ * elfxx-riscv.c (riscv_supported_std_ext): Added h with version 1.0 after v.

2022-05-27Replace bfd_hostptr_t with uintptr_tAlan Modra1-6/+6
bfd_hostptr_t is defined as a type large enough to hold either a long or a pointer. It mostly appears in the coff backend code in casts. include/coff/internal.h struct internal_syment and union internal_auxent have the only uses in data structures, where comparison with include/coff/external.h and other code reveals that the type only needs to be large enough for a 32-bit integer or a pointer. That should mean replacing with uintptr_t is OK.
2022-05-27Remove use of bfd_uint64_t and similarAlan Modra3-33/+33
Requiring C99 means that uses of bfd_uint64_t can be replaced with uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_* and tidies a few places that print 64-bit values.

2022-04-04objdump/opcodes: add syntax highlighting to disassembler outputAndrew Burgess1-5/+83
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.

2022-03-23include, libctf, ld: extend variable section to contain functions tooNick Alcock1-4/+4
The CTF variable section is an optional (usually-not-present) section in the CTF dict which contains name -> type mappings corresponding to data symbols that are present in the linker input but not in the output symbol table: the idea is that programs that use their own symbol- resolution mechanisms can use this section to look up the types of symbols they have found using their own mechanism. Because these removed symbols (mostly static variables, functions, etc) all have names that are unlikely to appear in the ELF symtab and because very few programs have their own symbol-resolution mechanisms, a special linker flag (--ctf-variables) is needed to emit this section. Historically, we emitted only removed data symbols into the variable section. This seemed to make sense at the time, but in hindsight it really doesn't: functions are symbols too, and a C program can look them up just like any other type. So extend the variable section so that it contains all static function symbols too (if it is emitted at all), with types of kind CTF_K_FUNCTION. This is a little fiddly. We relied on compiler assistance for data symbols: the compiler simply emits all data symbols twice, once into the symtypetab as an indexed symbol and once into the variable section. Rather than wait for a suitably adjusted compiler that does the same for function symbols, we can pluck unreported function symbols out of the symtab and add them to the variable section ourselves. While we're at it, we do the same with data symbols: this is redundant right now because the compiler does it, but it costs very little time and lets the compiler drop this kludge and save a little space in .o files. include/ * ctf.h: Mention the new things we can see in the variable section. ld/ * testsuite/ld-ctf/data-func-conflicted-vars.d: New test. libctf/ * ctf-link.c (ctf_link_deduplicating_variables): Duplicate symbols into the variable section too. * ctf-serialize.c (symtypetab_delete_nonstatic_vars): Rename to...

2022-03-16PowerPC64 extended instructions in powerpc_macrosAlan Modra1-3/+5
The extended instructions implemented in powerpc_macros aren't used by the disassembler. That means instructions like "sldi r3,r3,2" appear in disassembly as "rldicr r3,r3,2,61", which is annoying since many other extended instructions are shown. Note that some of the instructions moved out of the macro table to the opcode table won't appear in disassembly, because they are aliases rather than a subset of the underlying raw instruction. If enabled, rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all occurrences of rotldi, rldicl, rldicr, rldic and rldimi.
