Mips disassembler

Question

So, I am looking for disassembler code for MIPS commands, for example: if the program gets word of command like 3c1d8010, I want to get the name of the command and the registers, which it uses: lui sp,0x8010

examples: 25080268 addiu t0,t0,616 40806800 mtc0 zero,$13

I know, that it is possible to write by myself, but maybe somebody has done it already.

Many thanks in advance!

Answer 1

Try capstone. They have a good documentation with samples like the following:

 # test1.py
 from capstone import *

 CODE = b"\x55\x48\x8b\x05\xb8\x13\x00\x00"

 md = Cs(CS_ARCH_X86, CS_MODE_64)
 for i in md.disasm(CODE, 0x1000):
     print("0x%x:\t%s\t%s" %(i.address, i.mnemonic, i.op_str))

Output sample:

$ python test1.py

0x1000: push    rbp
0x1001: mov rax, qword ptr [rip + 0x13b8]

According to the docs they support MIPS and of course they have code on GitHub.

If you want to have quick access without installing anything, try The online disassembler.

Answer 3

you can try radare2

E:\R2>rasm2.exe -a mips -e -d -
25080268
addiu t0, t0, 0x268
40806800
mtc0 zero, t5, 0

use mips.gnu to get the output you queried

E:\R2>rasm2.exe -a mips.gnu -e -d -
25080268
addiu t0, t0, 616
40806800
mtc0 zero, $13

rasm2 -h should show the switches

-a = arch (use -L to list the numerous architectures it supports)
-e = to tell that the input is Big-Endian
-d = Disassemble 
-  = to provide input from Stdin
