}

A trait that represents the functions needed to be implemented to generate code for a module.

Required methods

fn new() -> Self

Creates a new module code generator.

fn new_with_target(
    triple: Option<String>,
    cpu_name: Option<String>,
    cpu_features: Option<String>
) -> Self

Creates a new module code generator for specified target.

fn backend_id() -> &'static str

Returns the backend id associated with this MCG.

fn feed_import_function(&mut self, _sigindex: SigIndex) -> Result<(), E>

Adds an import function.

fn feed_signatures(
    &mut self,
    signatures: Map<SigIndex, FuncSig>
) -> Result<(), E>

Sets the signatures.

fn feed_function_signatures(
    &mut self,
    assoc: Map<FuncIndex, SigIndex>
) -> Result<(), E>

Sets function signatures.

fn check_precondition(&mut self, module_info: &ModuleInfo) -> Result<(), E>

Checks the precondition for a module.

fn next_function(
    &mut self,
    module_info: Arc<RwLock<ModuleInfo>>,
    loc: WasmSpan
) -> Result<&mut FCG, E>

Creates a new function and returns the function-scope code generator for it.

fn finalize(
    self,
    module_info: &ModuleInfo
) -> Result<(RM, Option<DebugMetadata>, Box<dyn CacheGen>), E>

Finalizes this module.

unsafe fn from_cache(
    cache: Artifact,
    _: Token
) -> Result<ModuleInner, CacheError>

Creates a module from cache.

Provided methods

fn requires_pre_validation() -> bool

It sets if the current compiler requires validation before compilation

fn feed_compiler_config(&mut self, _config: &CompilerConfig) -> Result<(), E>

Feeds the compiler config.
