2024-07-26microMIPS: Add MT ASE instruction set supportYunQiang Su1-0/+3
Add the MT ASE instruction operand types and encodings to the microMIPS opcode table and enable the assembly of these instructions in GAS from MIPSr2 onwards. Update the binutils and GAS testsuites accordingly.

2024-03-01s390: Print base register 0 as "0" in disassemblyJens Remus1-0/+2
Base and index register 0 have no effect in address computation: "A value of zero in the B [base] or X [index] field specifies that no base or index is to be applied, and, thus, general register 0 cannot be designated as containing a base address or index." IBM z/Architecture Principles of Operation [1], chapter "Organization", section "General Registers". Index register 0 is omitted in the s390 disassembly. Base register 0 is omitted in D(B), D(L,B) and D(X,B) - the latter only if the index register is zero. To make it more apparent print base register 0 as "0" instead of "%r0", whenever it would still be printed in the disassembly.

2023-12-04s390: Support for jump visualization in disassemblyJens Remus1-0/+2
Add support for jump visualization for the s390 architecture in disassembly: objdump -d --visualize-jumps ... Annotate the (conditional) jump and branch relative instructions with information required for jump visualization: - jump: Unconditional jump / branch relative. - condjump: Conditional jump / branch relative. - jumpsr: Jump / branch relative to subroutine. Unconditional jump and branch relative instructions are annotated as jump. Conditional jump and branch relative instructions, jump / branch relative on count/index, and compare and jump / branch relative instructions are annotated as condjump. Jump and save (jas, jasl) and branch relative and save (bras, brasl) instructions are annotated as jumpsr (jump to subroutine). Provide instruction information required for jump visualization during disassembly. The instruction type is provided after determining the opcode. For non-code it is set to dis_noninsn. Otherwise it defaults to dis_nonbranch. No annotation is done for data reference instructions (i.e. instruction types dis_dref and dis_dref2). Note that the instruction type needs to be provided before printing of the instruction, as it is used in print_address_func() to translate the argument value into an address if it is assumed to be a PC-relative offset. Note that this is never the case on s390, as print_address_func() is only called with addresses and never with offsets. The target of the (conditional) jump and branch relative instructions is provided during print, when the PC relative operand is decoded. include/ * opcode/s390.h: Define opcode flags to annotate instruction class information for jump visualization: S390_INSTR_FLAG_CLASS_BRANCH, S390_INSTR_FLAG_CLASS_RELATIVE, S390_INSTR_FLAG_CLASS_CONDITIONAL, and S390_INSTR_FLAG_CLASS_SUBROUTINE.

2022-04-04objdump/opcodes: add syntax highlighting to disassembler outputAndrew Burgess1-0/+4
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.

This adds support for efi-*-aarch64 by virtue of adding a new PEI target pei-aarch64-little. This is not a full target and only exists to support EFI at this time. This means that this target does not support relocation processing and is mostly a container format. This format has been added to elf based aarch64 targets such that efi images can be made natively on Linux. However this target is not valid for use with gas but only with objcopy. With these changes the resulting file is recognized as an efi image by third party tools: > pecli info hello.efi Metadata ================================================================================ MD5: 598c32a778b0f0deebe977fef8578c4e SHA1: 4580121edd5cb4dc40f51b28f171fd15250df84c SHA256: 3154bd7cf42433d1c957f6bf55a17ad8c57ed41b29df2d485703349fd6ff1d5c Imphash: Size: 47561 bytes Type: PE32+ executable (EFI application) (stripped to external PDB), for MS Windows Compile Time: 1970-01-01 00:00:00 (UTC - 0x0 ) Entry point: 0x2000 (section .text) Sections ================================================================================ Name RWX VirtSize VirtAddr RawAddr RawSize Entropy md5 .text R-X 0x5bb0 0x2000 0x400 0x5c00 6.39 551fbc264256a3f387de8a891500ae0d .reloc R-- 0xc 0x8000 0x6000 0x200 0.02 0c45f6d812d079821c1d54c09ab89e1d .data RW- 0x1d88 0x9000 0x6200 0x1e00 4.18 5d1137c09f01289dc62bf754f7290db3 .dynamic RW- 0xf0 0xb000 0x8000 0x200 0.34 5c94ed3206f05a277e6f04fbf131f131 .rela R-- 0xe58 0xc000 0x8200 0x1000 1.87 8b5c6bc30f3acb7ca7bf2e6789d68519 .dynsym R-- 0x138 0xd000 0x9200 0x200 0.96 bdcf5101da51aadc663ca8859f88138c Imports ================================================================================ Any magic number is based on the Microsoft PE specification [1].
