Windows support is broken on the latest stable Rust version

[gnzlbg]

Why? no idea.

I'm not sure what you mean by "is broken", but on my machine, it works but doesn't show any relevant symbols from my crate, only dependencies. and strangely, a fmt implementation.

Hi Steve,

it works but doesn't show any relevant symbols from my crate, only dependencies.

do you have a reproducer ? Is that the output of calling cargo asm without a path? Are you sure that the symbols are there (e.g. they are not #[inline] functions, generic functions, etc. ?)

I should have added a link to the latest appveyor builds: https://ci.appveyor.com/project/gnzlbg/cargo-asm/branch/master

Basically, for our test crate, it is able to find the right function, but printing the function name appears to be failing, and detecting the end of a function appears to be failing too sometimes.

Without a windows machine it is hard to debug this :/

generic functions

Ah, so this is

struct List<T> {
    item: T,
}

impl<T> List<T> {
   fn push_back<T>(&mut self, T)

So yeah, that'd be generic. Oops, I must have missed this restriction. Sorry about the spam :/

Don't worry, so yes, generic functions do not exist in the emitted machine code unless they are actually used (how could they when types are not specified?). If you want to generate the assembly for one you can just create a temporary function for that, e.g.,

pub fn list_push_back(l: &mut List<i32>, x: i32) {
    l.push_back(x);
}

you need to make it pub so that the compiler must actually generate it, otherwise dead code elimination will remove it.

I did that and it works!
