wasmer-compiler

This crate is the base for Compiler implementations.

It performs the translation from a Wasm module into a basic ModuleInfo, but leaves the Wasm function bytecode translation to the compiler implementor.

Here are some of the Compilers provided by Wasmer:

• Singlepass,
• Cranelift,
• LLVM.

How to create a compiler

To create a compiler, one needs to implement two traits:

1. CompilerConfig, that configures and creates a new compiler,
2. Compiler, the compiler itself that will compile a module.

```rust /// The compiler configuration options. pub trait CompilerConfig { /// Gets the custom compiler config fn compiler(&self) -> Box; }

/// An implementation of a compiler from parsed WebAssembly module to compiled native code. pub trait Compiler { /// Compiles a parsed module. /// /// It returns the [Compilation] or a [CompileError]. fn compilemodule<'data, 'module>( &self, target: &Target, compileinfo: &'module mut CompileModuleInfo, moduletranslation: &ModuleTranslationState, // The list of function bodies functionbody_inputs: PrimaryMap>, ) -> Result; } ```

Acknowledgments

This project borrowed some of the code strucutre from the [cranelift-wasm] crate, however it's been adapted to not depend on any specific IR and be abstract of any compiler.
