示例1: EmitForDispose

		public override void EmitForDispose (EmitContext ec, Iterator iterator, Label end, bool have_dispatcher)
		{
			if (emitted_dispose)
				return;

			emitted_dispose = true;

			Label end_of_try = ec.DefineLabel ();

			// Ensure that the only way we can get into this code is through a dispatcher
			if (have_dispatcher)
				ec.Emit (OpCodes.Br, end);

			ec.BeginExceptionBlock ();

			ec.MarkLabel (dispose_try_block);

			Label [] labels = null;
			for (int i = 0; i < resume_points.Count; ++i) {
				ResumableStatement s = (ResumableStatement) resume_points [i];
				Label ret = s.PrepareForDispose (ec, end_of_try);
				if (ret.Equals (end_of_try) && labels == null)
					continue;
				if (labels == null) {
					labels = new Label [resume_points.Count];
					for (int j = 0; j < i; ++j)
						labels [j] = end_of_try;
				}
				labels [i] = ret;
			}

			if (labels != null) {
				int j;
				for (j = 1; j < labels.Length; ++j)
					if (!labels [0].Equals (labels [j]))
						break;
				bool emit_dispatcher = j < labels.Length;

				if (emit_dispatcher) {
					//SymbolWriter.StartIteratorDispatcher (ec.ig);
					ec.Emit (OpCodes.Ldloc, iterator.CurrentPC);
					ec.EmitInt (first_resume_pc);
					ec.Emit (OpCodes.Sub);
					ec.Emit (OpCodes.Switch, labels);
					//SymbolWriter.EndIteratorDispatcher (ec.ig);
				}

				foreach (ResumableStatement s in resume_points)
					s.EmitForDispose (ec, iterator, end_of_try, emit_dispatcher);
			}

			ec.MarkLabel (end_of_try);

			ec.BeginFinallyBlock ();

示例2: DoEmit

		protected sealed override void DoEmit (EmitContext ec)
		{
			EmitPreTryBody (ec);

			if (resume_points != null) {
				ec.EmitInt ((int) Iterator.State.Running);
				ec.Emit (OpCodes.Stloc, iter.CurrentPC);
			}

			ec.BeginExceptionBlock ();

			if (resume_points != null) {
				ec.MarkLabel (resume_point);

				// For normal control flow, we want to fall-through the Switch
				// So, we use CurrentPC rather than the $PC field, and initialize it to an outside value above
				ec.Emit (OpCodes.Ldloc, iter.CurrentPC);
				ec.EmitInt (first_resume_pc);
				ec.Emit (OpCodes.Sub);

				Label [] labels = new Label [resume_points.Count];
				for (int i = 0; i < resume_points.Count; ++i)
					labels [i] = resume_points [i].PrepareForEmit (ec);
				ec.Emit (OpCodes.Switch, labels);
			}

			EmitTryBody (ec);

			ec.BeginFinallyBlock ();

			Label start_finally = ec.DefineLabel ();
			if (resume_points != null) {
				ec.Emit (OpCodes.Ldloc, iter.SkipFinally);
				ec.Emit (OpCodes.Brfalse_S, start_finally);
				ec.Emit (OpCodes.Endfinally);
			}

			ec.MarkLabel (start_finally);
			EmitFinallyBody (ec);

			ec.EndExceptionBlock ();
