[Feature request] Rust symbol demangling

[milostosic]

Thanks! Just published MTuner v4.7 which includes Rust demangler. Seems to work with your example.

Hey, I did a quick & dirty integration of rust-demangle.c to rdebug, but would need some test cases - if you're can provide me with some simple rust programs for testing I could likely add that quickly.

Here you go: This binary does nothing but constantly reallocate 8 bytes in a uncapped loop without command-line arguments, and if you pass the leak argument it leaks those 8 bytes (never frees them)

there is basically no functions here, but it should work to test demangling (it shows them mangled in my mtuner install)

Code

use std::{env, hint::black_box};
fn main() {
    let args: Vec<_> = env::args().collect();
    if args.len() > 1 && args[1].contains("leak") {
        loop {
            let big: Vec<u8> = vec![0; 8];
            Box::new(black_box(big)).leak();
        }
    } else {
        loop {
            let big: Vec<u8> = vec![0; 8];
            let _ = black_box(big);
        }
    }
}
