Rust: `f32::round` fails to link with emscripten (llvm_round_f32 not found)

[jonas-schievink]

fn main() {
    let float = 0.5f32;
    float.round();
}

Compile with rustc test.rs --target=asmjs-unknown-emscripten and emcc will abort with an error:

error: unresolved symbol: llvm_round_f32

[jonas-schievink]

It is also complaining about unexpected EOF:

/home/jonas/emsdk_portable/clang/fastcomp/build_incoming_64/bin/llvm-nm: /home/jonas/.multirust/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/asmjs-unknown-emscripten/lib/libcompiler_builtins-e428224f6caf212a.rlib(rust.metadata.bin) The end of the file was unexpectedly encountered

This happens for every rlib in the standard library, but I'm assuming this is just spurious and will go away when the real bug is fixed.

I'm seeing only the latter in my experimentation:

(Etc.)

I have local path overrides for num_cpus and glutin.

[jeffparsons]

I'm running rustc 1.14.0-nightly (098d22845 2016-10-13).

[tomaka]

The missing symbol and the end of file errors should probably be two different issues.

error: unresolved symbol: llvm_round_f32

The symbol should be added to emscripten, since it doesn't seem to have it.
See this PR as an example of how to do it.

[badboy]

Fixed upstream: https://github.com/kripken/emscripten/pull/4662

[iximiuz]

So, what about The end of the file was unexpectedly encountered part? Having plenty of such warnings while trying to complile my app that uses rust-sdl2 with emscripten.
