+; Test for handlerdata when the function has landingpad and nounwind.
+
+; This test case checks whether the handlerdata is generated for the function
+; with landingpad instruction, even if the function has "nounwind" atttribute.
+;
+; For example, although the following function never throws any exception,
+; however, it is still required to generate LSDA, otherwise, we can't catch
+; the exception properly.
