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 locale_resource(&self) -> &'static str

Locale resources for diagnostic messages - a string the content of the Fluent resource. Called before init so that all other functions are able to emit translatable diagnostics.

fn init(&self, sess: &Session)

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

fn print( &self, req: &PrintRequest, out: &mut dyn PrintBackendInfo, sess: &Session )

fn print_passes(&self)

fn print_version(&self)

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

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, outputs: &OutputFilenames ) -> (CodegenResults, FxIndexMap<WorkProductId, WorkProduct>)

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

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

This is called on the returned CodegenResults 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.

fn metadata_loader( &self ) -> Box<dyn MetadataLoader + DynSync + DynSend + Send + Sync>

The metadata loader used to load rlib and dylib metadata.

fn supports_parallel(&self) -> bool

Returns true if this backend can be safely called from multiple threads.

impl ExtraBackendMethods for LlvmCodegenBackend

fn codegen_allocator<'tcx>( &self, tcx: TyCtxt<'tcx>, module_name: &str, kind: AllocatorKind, alloc_error_handler_kind: AllocatorKind ) -> ModuleLlvm

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.

fn target_machine_factory( &self, sess: &Session, optlvl: OptLevel, target_features: &[String] ) -> TargetMachineFactoryFn<Self>

fn spawn_named_thread<F, T>( time_trace: bool, name: String, f: F ) -> Result<JoinHandle<T>>

where F: FnOnce() -> T + Send + 'static, T: Send + 'static,

impl WriteBackendMethods for LlvmCodegenBackend

type Module = ModuleLlvm

type ModuleBuffer = ModuleBuffer

type TargetMachine = OwnedTargetMachine

type TargetMachineError = LlvmError<'static>

type ThinData = ThinData

type ThinBuffer = ThinBuffer

fn print_pass_timings(&self)

fn print_statistics(&self)

fn run_link( cgcx: &CodegenContext<Self>, dcx: &DiagCtxt, modules: Vec<ModuleCodegen<Self::Module>> ) -> Result<ModuleCodegen<Self::Module>, FatalError>

Merge all modules into main_module and returning it

fn run_fat_lto( cgcx: &CodegenContext<Self>, 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.

fn run_thin_lto( cgcx: &CodegenContext<Self>, modules: Vec<(String, Self::ThinBuffer)>, cached_modules: Vec<(SerializedModule<Self::ModuleBuffer>, WorkProduct)> ) -> Result<(Vec<LtoModuleCodegen<Self>>, Vec<WorkProduct>), FatalError>

Performs thin LTO by performing necessary global analysis and returning two lists, one of the modules that need optimization and another for modules that can simply be copied over from the incr. comp. cache.

unsafe fn optimize( cgcx: &CodegenContext<Self>, dcx: &DiagCtxt, module: &ModuleCodegen<Self::Module>, config: &ModuleConfig ) -> Result<(), FatalError>

fn optimize_fat( cgcx: &CodegenContext<Self>, module: &mut ModuleCodegen<Self::Module> ) -> Result<(), FatalError>

unsafe fn codegen( cgcx: &CodegenContext<Self>, dcx: &DiagCtxt, module: ModuleCodegen<Self::Module>, config: &ModuleConfig ) -> Result<CompiledModule, FatalError>

fn prepare_thin( module: ModuleCodegen<Self::Module> ) -> (String, Self::ThinBuffer)

fn serialize_module( module: ModuleCodegen<Self::Module> ) -> (String, Self::ModuleBuffer)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
