neither Wasm object file nor LLVM bitcode from all wasm cdylib builds #136109
Closed as duplicate of#132802
Description
Build a cdylib for wasm32-unknown-unknown using nightly-2025-01-26 (rustc 1.86.0-nightly (f7cc13af8 2025-01-25)) — no Rust code needed in the library:
[package]
name = "foo"
version = "0.1.0"
edition = "2021"
[lib]
crate-type = ["cdylib"]This produces these warnings:

= note: `#[warn(linker_messages)]` on by defaultnightly-2025-01-25 and earlier does not produce these warnings, presumably because they are new in #119286. Built cdylibs still function as intended, but I don't know whether any of my code would be attempting to use the code mentioned in the warnings.
