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:
How to create a compiler
To create a compiler, one needs to implement two traits:
CompilerConfig
, that configures and creates a new compiler,Compiler
, the compiler itself that will compile a module.
/// The compiler configuration options.
pub trait CompilerConfig {
/// Gets the custom compiler config
fn compiler(&self) -> Box<dyn Compiler>;
}
/// 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 compile_module<'data, 'module>(
&self,
target: &Target,
compile_info: &'module CompileModuleInfo,
module_translation: &ModuleTranslationState,
// The list of function bodies
function_body_inputs: PrimaryMap<LocalFunctionIndex, FunctionBodyData<'data>>,
) -> Result<Compilation, CompileError>;
}
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.
