std: Add a new wasm32-unknown-unknown target This commit adds a new target to the compiler: wasm32-unknown-unknown. This target is a reimagining of what it looks like to generate WebAssembly code from Rust. Instead of using Emscripten which can bring with it a weighty runtime this instead is a target which uses only the LLVM backend for WebAssembly and a "custom linker" for now which will hopefully one day be direct calls to lld. Notable features of this target include: * There is zero runtime footprint. The target assumes nothing exists other than the wasm32 instruction set. * There is zero toolchain footprint beyond adding the target. No custom linker is needed, rustc contains everything. * Very small wasm modules can be generated directly from Rust code using this target. * Most of the standard library is stubbed out to return an error, but anything related to allocation works (aka `HashMap`, `Vec`, etc). * Naturally, any `#[no_std]` crate should be 100% compatible with this new target. This target is currently somewhat janky due to how linking works. The "linking" is currently unconditional whole program LTO (aka LLVM is being used as a linker). Naturally that means compiling programs is pretty slow! Eventually though this target should have a linker. This target is also intended to be quite experimental. I'm hoping that this can act as a catalyst for further experimentation in Rust with WebAssembly. Breaking changes are very likely to land to this target, so it's not recommended to rely on it in any critical capacity yet. We'll let you know when it's "production ready". ### Building yourself First you'll need to configure the build of LLVM and enable this target ``` $ ./configure --target=wasm32-unknown-unknown --set llvm.experimental-targets=WebAssembly ``` Next you'll want to remove any previously compiled LLVM as it needs to be rebuilt with WebAssembly support. You can do that with: ``` $ rm -rf build ``` And then you're good to go! A `./x.py build` should give you a rustc with the appropriate libstd target. ### Test support Currently testing-wise this target is looking pretty good but isn't complete. I've got almost the entire `run-pass` test suite working with this target (lots of tests ignored, but many passing as well). The `core` test suite is [still getting LLVM bugs fixed](https://reviews.llvm.org/D39866) to get that working and will take some time. Relatively simple programs all seem to work though! In general I've only tested this with a local fork that makes use of LLVM 5 rather than our current LLVM 4 on master. The LLVM 4 WebAssembly backend AFAIK isn't broken per se but is likely missing bug fixes available on LLVM 5. I'm hoping though that we can decouple the LLVM 5 upgrade and adding this wasm target! ### But the modules generated are huge! It's worth nothing that you may not immediately see the "smallest possible wasm module" for the input you feed to rustc. For various reasons it's very difficult to get rid of the final "bloat" in vanilla rustc (again, a real linker should fix all this). For now what you'll have to do is: cargo install --git https://github.com/alexcrichton/wasm-gc wasm-gc foo.wasm bar.wasm And then `bar.wasm` should be the smallest we can get it! --- In any case for now I'd love feedback on this, particularly on the various integration points if you've got better ideas of how to approach them!

// The wasm32-unknown-unknown target is currently a highly experimental version
|
||||
// of a wasm-based target which does *not* use the Emscripten toolchain. Instead
|
||||
// this is a pretty flavorful (aka hacked up) target right now. The definition
|
||||
// and semantics of this target are likely to change and so this shouldn't be
|
||||
// relied on just yet.
|
||||
//
|
||||
// In general everyone is currently waiting on a linker for wasm code. In the
|
||||
// meantime we have no means of actually making use of the traditional separate
|
||||
// compilation model. At a high level this means that assembling Rust programs
|
||||
// into a WebAssembly program looks like:
|
||||
//
|
||||
// 1. All intermediate artifacts are LLVM bytecode. We'll be using LLVM as
|
||||
// a linker later on.
|
||||
// 2. For the final artifact we emit one giant assembly file (WebAssembly
|
||||
// doesn't have an object file format). To do this we force LTO to be turned
|
||||
// on (`requires_lto` below) to ensure all Rust code is in one module. Any
|
||||
// "linked" C library is basically just ignored.
|
||||
// 3. Using LLVM we emit a `foo.s` file (assembly) with some... what I can only
|
||||
// describe as arcane syntax. From there we need to actually change this
|
||||
// into a wasm module. For this step we use the `binaryen` project. This
|
||||
// project is mostly intended as a WebAssembly code generator, but for now
|
||||
// we're just using its LLVM-assembly-to-wasm-module conversion utilities.
|
||||
//
|
||||
// And voila, out comes a web assembly module! There's some various tweaks here
|
||||
// and there, but that's the high level at least. Note that this will be
