README.md

I made a minimal Rust demo.

This needs a rebuild of the core library with xargo (https://github.com/japaric/xargo) for working soft floating-point support.

Steps:

$ rustup default nightly

$ rustup target add powerpc64le-unknown-linux-gnu

$ rustup component add rust-src

$ cargo install xargo

$ make $ make run

ln -sf hello_world.bin main_ram.bin ../core_tb > /dev/null Hello World Rust i 2 5 5 i 3 3.3333333333333335 3.3333333333333335 [-9, -6, 2, 3] !panicked at 'test', src/lib.rs:58:5
