pub fn new() -> Box<dyn CodegenBackend>

Trait Implementations

impl Clone for LlvmCodegenBackend

fn clone(&self) -> LlvmCodegenBackend

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CodegenBackend for LlvmCodegenBackend

fn init(&self, sess: &Session)

fn print(&self, req: PrintRequest, sess: &Session)

fn print_passes(&self)

fn print_version(&self)

fn target_features(&self, sess: &Session) -> Vec<Symbol>

fn metadata_loader(&self) -> Box<MetadataLoaderDyn>

fn provide(&self, providers: &mut Providers)

fn provide_extern(&self, providers: &mut Providers)

fn codegen_crate<'tcx>(
    &self,
    tcx: TyCtxt<'tcx>,
    metadata: EncodedMetadata,
    need_metadata_module: bool
) -> Box<dyn Any>

fn join_codegen(
    &self,
    ongoing_codegen: Box<dyn Any>,
    sess: &Session
) -> Result<(CodegenResults, FxHashMap<WorkProductId, WorkProduct>), ErrorReported>

This is called on the returned Box<dyn Any> from codegen_backend

fn link(
    &self,
    sess: &Session,
    codegen_results: CodegenResults,
    outputs: &OutputFilenames
) -> Result<(), ErrorReported>

This is called on the returned Box<dyn Any> from join_codegen

fn target_override(&self, _opts: &Options) -> Option<Target>

If this plugin provides additional builtin targets, provide the one enabled by the options here. Be careful: this is called before init() is called.

impl ExtraBackendMethods for LlvmCodegenBackend

fn new_metadata(&self, tcx: TyCtxt<'_>, mod_name: &str) -> ModuleLlvm

fn write_compressed_metadata<'tcx>(
    &self,

fn compile_codegen_unit(
    &self,
    tcx: TyCtxt<'_>,
    cgu_name: Symbol
) -> (ModuleCodegen<ModuleLlvm>, u64)

This generates the codegen unit and returns it along with a u64 giving an estimate of the unit’s processing cost.

    modules: Vec<FatLTOInput<Self>>,
    cached_modules: Vec<(SerializedModule<Self::ModuleBuffer>, WorkProduct)>
) -> Result<LtoModuleCodegen<Self>, FatalError>

Performs fat LTO by merging all modules into a single one and returning it for further optimization.
