+; This test is based on the following code:
+;
+; void test()
+; {
+;   try {
+;     may_throw();
+;   } catch (...) {
+;     handle_exception();
+;   }
+; }
+;
+; Parts of the IR have been hand-edited to simplify the test case.
+; The full IR will be restored when Windows C++ EH support is complete.
