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.

2022-04-02gdb: rename floatformats_ia64_quad to floatformats_ieee_quadTiezhu Yang1-3/+3
It is better to rename floatformats_ia64_quad to floatformats_ieee_quad to reflect the reality, and then we can clean up the related code. As Tom Tromey said [1]: These files are maintained in gcc and then imported into the binutils-gdb repository, so any changes to them will have to be proposed there first. the related changes have been merged into gcc master now [2], it is time to do it for gdb.

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. (Or many occurrences in the case of clrlsldi if n <= b was added to the extract functions.)

2022-02-11gdb/fortran: support ptype and print commands for namelist variablesBhuvanendra Kumar N1-1/+1
Gfortran supports namelists (a Fortran feature); it emits DW_TAG_namelist and DW_TAG_namelist_item dies. But gdb does not process these dies and does not support 'print' or 'ptype' commands on namelist variables. An attempt to print namelist variables results in gdb bailing out with the error message as shown below. (gdb) print nml No symbol "nml" in current context. This commit is to make the print and ptype commands work for namelist variables and its items. Sample output of these commands is shared below, with fixed gdb. (gdb) ptype nml type = Type nml integer(kind=4) :: a integer(kind=4) :: b End Type nml (gdb) print nml $1 = ( a = 10, b = 20 )

2022-01-05elf: Set p_align to the minimum page size if possibleH.J. Lu1-0/+3
Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align values of 0x10000 even if no section alignment is greater than 0x1000. The issue is more general and probably affects other targets with multiple page sizes. While file layout absolutely must take 64K page size into account, that does not have to be reflected in the p_align value. If running on a 64K kernel, the file will be loaded at a 64K page boundary by necessity. On a 4K kernel, 64K alignment is not needed. The glibc loader has been fixed to honor p_align: https://sourceware.org/bugzilla/show_bug.cgi?id=28676 similar to kernel: commit ce81bb256a224259ab686742a6284930cbe4f1fa Author: Chris Kennelly <ckennelly@google.com> Date: Thu Oct 15 20:12:32 2020 -0700 fs/binfmt_elf: use PT_LOAD p_align values for suitable start address This means that on 4K kernels, we will start to do extra work for 64K p_align, but this pointless for pretty much all binaries (whose section alignment rarely exceeds 16). The minimum page size is used, instead of the maximum section alignment due to this glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28688 It has been fixed in glibc 2.35. But linker output must work on existing glibc binaries. 1. Set p_align to the minimum page size while laying out segments aligning to the maximum page size or section alignment. The run-time loader can align segments to the minimum page size or above, depending on system page size. 2. If -z max-page-size=NNN is used, p_align will be set to the maximum page size or the largest section alignment. 3. If a section requires alignment higher than the minimum page size, don't set p_align to the minimum page size. 4. If a section requires alignment higher than the maximum page size, set p_align to the section alignment. 5. For objcopy, when the minimum page size != the maximum page size, p_align may be set to the minimum page size while segments are aligned to the maximum page size. In this case, the input p_align will be ignored and the maximum page size will be used to align the ouput segments. 6. Update linker to disallow the common page size > the maximum page size. 7. Update linker to avoid the common page size > the maximum page size. 8.

2021-12-16arm: Add support for Armv8.7-A and Armv8.8-ARichard Sandiford1-0/+2
This patch adds AArch32 support for -march=armv8.[78]-a. The behaviour of the new options can be expressed using a combination of existing feature flags and tables. The cpu_arch_ver entries are technically redundant but it seemed less surprising to include them anyway. include/ * opcode/arm.h (ARM_ARCH_V8_7A, ARM_ARCH_V8_8A): New macros. gas/ * doc/c-arm.texi: Add armv8.7-a and armv8.8-a. * config/tc-arm.c (armv87a_ext_table, armv88a_ext_table): New macros.

2021-12-16aarch64: Add support for Armv9.1-A to Armv9.3-ARichard Sandiford1-40/+62
This patch adds AArch64 support for -march=armv9.[123]-a. The behaviour of the new options can be expressed using a combination of existing feature flags, so we don't need to eat into the vanishing number of spare AARCH64_FEATURE_* bits. Hoewver, it was more convenient to separate out the |s of feature flags so that Armv9.1-A could reuse the set for Armv8.6-A, and so on. include/ * opcode/aarch64.h (AARCH64_ARCH_V8_FEATURES): New macro, split out from...

2021-12-16RISC-V: Support svinval extension with frozen version 1.0.Nelson Chu2-0/+17
According to the privileged spec, there are five new instructions for svinval extension. Two of them (HINVAL.VVMA and HINVAL.GVMA) need to enable the hypervisor extension. But there is no implementation of hypervisor extension in mainline for now, so let's consider the related issues later. 31..25 24..20 19..15 14..12 11...7 6..2 1..0 sinval.vma 0001011 rs2 rs1 000 00000 11100 11 sfence.w.inval 0001100 00000 00000 000 00000 11100 11 sfence.inval.ir 0001100 00001 00000 000 00000 11100 11 hinval.vvma 0010011 rs2 rs1 000 00000 11100 11 hinval.gvma 0110011 rs2 rs1 000 00000 11100 11 This patch is cherry-picked from the riscv integration branch since the svinval extension is frozen for now. Besides, we fix the funct7 encodings of hinval.vvma and hinval.gvma, from 0x0011011 and 0x0111011 to 0x0010011 and 0x0110011. bfd/ * elfxx-riscv.c (riscv_supported_std_s_ext): Added svinval.

2021-12-07Support AT_FXRNG and AT_KPRELOAD on FreeBSD.John Baldwin2-0/+6
FreeBSD's kernel has recently added two new ELF auxiliary vector entries. AT_FXRNG points to a root seed version for the kernel's PRNG. Userland can use this to reseed a userland PRNG after the kernel's PRNG has reseeded. AT_KPRELOAD is the base address of a kernel-provided vDSO. This change displays the proper name and description of these entries in 'info auxv'. include/ChangeLog: * elf/common.h (AT_FREEBSD_FXRNG, AT_FREEBSD_KPRELOAD): Define.
