Required Associated Types§

Required Methods§

Merge all modules into main_module and returning it

Source

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.

Source

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.

Source

fn print_pass_timings(&self)

Source

fn print_statistics(&self)

Source

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

Source

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

Source

unsafe fn optimize_thin( cgcx: &CodegenContext<Self>, thin: ThinModule<Self>, ) -> Result<ModuleCodegen<Self::Module>, FatalError>

Source

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

Source

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

Source

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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
