de8086

A 8086/8088 disassembler written in Rust. It is by no means perfect; it can not disassemble every instruction at the moment.

CLI

The CLI takes a filename as input, i.e.

de8086 ./test/kitchen_sink

Outputs:

; kitchen_sink

bits 16
mov cx, bx
mov ch, ah
mov dx, bx
...

Specifying the --verbose flag includes additional output.

de8086 ./test/kitchen_sink --verbose

Outputs:

; kitchen_sink

bits 16
; 10001001 11011001
mov cx, bx
; 10001000 11100101
mov ch, ah
; 10001001 11011010
mov dx, bx

API

de8086 comes with Parser and Writer structs for disassembly:

use de8086::{
    parser::Parser,
    writer::{Writer, WriterOptions},
};
use std::io::{stdout, Write};

fn run(bytes: &[u8]) {
    let mut writer = Writer::new(WriterOptions { verbose: false });
    let parser = Parser::build(bytes).unwrap();

    for instruction in parser {
        instruction.write(&mut writer);
    }

    stdout().write_all(writer.as_slice()).unwrap();
}
