I tried this code:

[package]
name = "test5"
version = "0.1.0"
authors = ["Mateusz Mikuła <mati865@gmail.com>"]
edition = "2018"

[lib]
crate-type = ["cdylib"]
// LLVM unwind library from MSYS2 repo
#[link(name = "unwind", kind = "static")]
extern "C" {}

#[no_mangle]
pub fn foo() {
    println!("Hello, world!");
}

I expected to see this happen:

$ cargo +stage2 b && nm target/debug/libtest5.dll.a | grep foo || echo "not found"
   Compiling test5 v0.1.0 (D:\msys64\tmp\test5)
    Finished dev [unoptimized + debuginfo] target(s) in 0.87s
0000000000000000 I __imp_foo
0000000000000000 T foo

stage2 is #72049

Instead, this happened:

$ cargo b && nm target/debug/libtest5.dll.a | grep foo || echo "not found"
   Compiling test5 v0.1.0 (D:\msys64\tmp\test5)
    Finished dev [unoptimized + debuginfo] target(s) in 0.57s
not found
