Required Methods§

source

fn vtables( &self, ) -> &RefCell<FxHashMap<(Ty<'tcx>, Option<PolyExistentialTraitRef<'tcx>>), Self::Value>>

source

fn get_fn(&self, instance: Instance<'tcx>) -> Self::Function

source

fn get_fn_addr(&self, instance: Instance<'tcx>) -> Self::Value

source

fn eh_personality(&self) -> Self::Value

source

fn sess(&self) -> &Session

source

fn codegen_unit(&self) -> &'tcx CodegenUnit<'tcx>

source

fn set_frame_pointer_type(&self, llfn: Self::Function)

source

fn apply_target_cpu_attr(&self, llfn: Self::Function)

source

fn declare_c_main(&self, fn_type: Self::Type) -> Option<Self::Function>

Declares the extern “C” main function for the entry point. Returns None if the symbol already exists.

Provided Methods§

source

fn apply_vcall_visibility_metadata( &self, _ty: Ty<'tcx>, _poly_trait_ref: Option<PolyExistentialTraitRef<'tcx>>, _vtable: Self::Value, )
