A light-weight and efficient ARMv7/Thumb/Thumb2 disassembler written in C with Python bindings. VFP/Neon/SIMD (it's all the same) support is upcoming!

Warning: project is no longer maintained, a better alternative might be capstone.

Example code

Using the darm library is fairly straightforward - just call the right function with the right parameter and you're all set. Following is an example of disassembling an ARMv7 instruction in C and printing its string representation to stdout.

#include <stdio.h>
#include "darm.h"

int main()
    darm_t d; darm_str_t str;

    if(darm_armv7_disasm(&d, 0x42424242) == 0 &&
            darm_str2(&d, &str, 1) == 0) {

        printf("-> %s\n", str.total);

And the exact same program, but using the Python bindings.

import darm

print str(darm.disasm_armv7(0x42424242))


The darm library is released under the BSD 3-Clause License, also known as BSD Simplified.
