2022-05-30RISC-V: Add zhinx extension supports.jiawei1-2/+3
The zhinx extension is a sub-extension in zfinx, corresponding to zfh extension but use GPRs instead of FPRs. This patch expanded the zfh insn class define, since zfh and zhinx use the same opcodes, thanks for Nelson's works. changelog in V2: Add missing classes of 'zfh' and 'zhinx' in "riscv_multi_subset_supports_ext". bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): New extensions.

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.

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...

When the machine is EM_AMDGPU, handle the various OS ABIs described here: https://llvm.org/docs/AMDGPUUsage.html#header For a binary with the HSA OS ABI, the change looks like: - OS/ABI: <unknown: 40> + OS/ABI: AMD HSA binutils/ChangeLog: * readelf.c (get_osabi_name): Handle EM_AMDGPU OS ABIs. include/ChangeLog: * elf/common.h (ELFOSABI_AMDGPU_PAL, ELFOSABI_AMDGPU_MESA3D): New.

2022-03-16bfd: add AMDGCN architectureSimon Marchi3-0/+42
Add support for the AMDGCN architecture to BFD. This is the bare minimum to get $ ./configure --target=amdgcn-hsa-amdhsa --disable-gas $ make all-binutils working later in this series. The specific AMDGCN models added here are a bit arbitrary, based on what we intend to initially support in GDB. This list will need to be updated in the future anyway. The complete up-to-date list of existing AMDGPU models can be found here: https://llvm.org/docs/AMDGPUUsage.html#processors The ELF format for this architecture is documented here: https://llvm.org/docs/AMDGPUUsage.html#elf-code-object The flags for the "HSA" OS ABI are properly versioned and documented on that page. But the NONE, PAL and MESA3D OS ABIs are not well documented nor versioned. Taking a peek at the LLVM source code, we see that they encode their flags the same way as HSA v3. For example, for PAL: https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601 So at least, we know that all AMDGPU objects (of which AMDGCN objects are a subset of) at the time of writing encode the specific GPU model in the EF_AMDGPU_MACH field of e_flags. bfd/ChangeLog: * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add cpu-amdgcn.c.

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.) The patch also fixes a small bug in opcode sanity checking. include/ * opcode/ppc.h (PPC_OPSHIFT_SH6): Define. opcodes/ * ppc-opc.c (insert_erdn, extract_erdn, insert_eldn, extract_eldn), (insert_crdn, extract_crdn, insert_rrdn, extract_rrdn), (insert_sldn, extract_sldn, insert_srdn, extract_srdn), (insert_erdb, extract_erdb, insert_csldn, extract_csldb), (insert_irdb, extract_irdn): New 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 )

2022-01-12gas: add visibility support for XCOFFClément Chigot2-0/+10
XCOFF assembly defines the visibility using an additional argument on several pseudo-ops: .globl, .weak, .extern and .comm. This implies that .globl and .weak syntax is different than the usual GNU syntax.
