Provided Methods

fn emulate_foreign_item( &mut self, link_name: Symbol, abi: Abi, args: &[OpTy<'tcx>], dest: &MPlaceTy<'tcx>, ret: Option<BasicBlock>, unwind: UnwindAction, ) -> InterpResult<'tcx, Option<(&'tcx Body<'tcx>, Instance<'tcx>)>>

Emulates calling a foreign item, failing if the item is not supported. This function will handle goto_block if needed. Returns Ok(None) if the foreign item was completely handled by this function. Returns Ok(Some(body)) if processing the foreign item is delegated to another function.

fn is_dyn_sym(&self, name: &str) -> bool

fn emulate_dyn_sym( &mut self, sym: DynSym, abi: Abi, args: &[OpTy<'tcx>], dest: &MPlaceTy<'tcx>, ret: Option<BasicBlock>, unwind: UnwindAction, ) -> InterpResult<'tcx>

Emulates a call to a DynSym.

fn lookup_exported_symbol( &mut self, link_name: Symbol, ) -> InterpResult<'tcx, Option<(&'tcx Body<'tcx>, Instance<'tcx>)>>

Lookup the body of a function that has link_name as the symbol name.
