Unicorn-engine

Rust bindings for the Unicorn emulator with utility functions.

Checkout Unicorn2 source code at dev branch.

use unicorn_engine::{Arch, Mode, Prot, SECOND_SCALE, Unicorn, RegisterARM};

fn main() {
    let arm_code32: Vec<u8> = vec![0x17, 0x00, 0x40, 0xe2]; // sub r0, #23

    let mut emu = Unicorn::new(Arch::ARM, Mode::LITTLE_ENDIAN).expect("failed to initialize Unicorn instance");
    emu.mem_map(0x1000, 0x4000, Prot::ALL).expect("failed to map code page");
    emu.mem_write(0x1000, &arm_code32).expect("failed to write instructions");

    emu.reg_write(RegisterARM::R0, 123).expect("failed write R0");
    emu.reg_write(RegisterARM::R5, 1337).expect("failed write R5");

    emu.emu_start(0x1000, (0x1000 + arm_code32.len()) as u64, 10 * SECOND_SCALE, 1000).expect("failed to start emulation");
    assert_eq!(emu.reg_read(RegisterARM::R0).unwrap(), 100);
    assert_eq!(emu.reg_read(RegisterARM::R5).unwrap(), 1337);
}

Further sample code can be found in tests.

Acknowledgements

These bindings were once based on Sébastien Duquette's (@ekse) unicorn-rs. We picked up the project, as it is no longer maintained. Thanks to all contributors.
