QUESTION
When you type a shell command in https://explainshell.com/ , you get an explanation of each part of the command and what the command does.
Is there a place where I could type in a bunch of x86 bytecode, and have it paresed byte by byte (and perhaps bit by bit for certain bytes) and explained similarly?
...ANSWER
Answered 2020-Apr-16 at 19:07Disassemblers will decode whole instructions back into asm. Some will group the bytes into prefixes, opcode, and later stuff. e.g. a 4-byte immediate or displacement in an addressing mode might be grouped without spaces, but separated from the opcode by a space.
Agner Fog's objconv disassembler does that. https://www.agner.org/optimize/#objconv
e.g. on a random .o file I had lying around from a recent SO question about x87 flags. Note that it's a .o so the addresses are based at 0 in each section.
More importantly, not how fld dword [value1]'s machine code is show as D9 (the opcode), 05 (the ModRM byte that encodes the addressing mode and in this case signals that there's a 4-byte displacement), and the 00000000 with a (d) note showing the 4-byte disp32.
