This project is not under development and does nothing useful. If you just want to compile Rust to WASM then the mainline Rust compiler can do that for you. Read https://rustwasm.github.io/book/
This doesn't do anything useful yet.
I recommend that you install rustup and then use it to install the current rustc nightly version:
Tested with nightly-2017-03-03
git clone https://github.com/brson/mir2wasm.git cd mir2wasm rustup override set nightly-2017-03-03
cargo run -q -- rust-examples/nocore-hello-world.rs
Do println debugging with
debug! so it goes to stderr and print it like:
RUST_LOG=mir2wasm cargo run -q -- rust-examples/nocore-hello-world.rs
rustc -Z unstable-options --unpretty=mir rust-examples/nocore-hello-world.rs
Plug this stuff into a wast file to print something:
(import $print_i32 "spectest" "print" (param i32)) (export "foo" $foo) ... (call_import $print_i32 (get_local $1))
- miri the MIR interpreter. mir2wasm is derived from it but shares no actual code. It probably should share code though, and there's lots to learn from miri.
