Apple ARM M1/M2 is not supported

[mike-code]

So I've tried to use the lib on my machine, using minimal example from your test suite, namely

src/main.rs

fn main() {
    println!("Hello, world!");
}

#[cfg(test)]
#[inline(never)]
fn the_ultimate_question() -> u32 {
    42
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_patch() {
        assert_eq!(the_ultimate_question(), 42);

        {
            let _guard = guerrilla::patch0(the_ultimate_question, || 24);

            assert_eq!(the_ultimate_question(), 24);
        }

        assert_eq!(the_ultimate_question(), 42);
    }
}

test result

I figured I'll show full trace as this is some low-level stuff
