+Hi,
+
+The attached patch makes sure that we create smaller object code for
+simple switch statements. We just make sure to flatten the switch
+statement into an if-else chain, basically.
+
+This fixes a size-regression as compared to gcc-3.4, as can be seen
+below.
+
+2007-04-15  Bernhard Fischer  <..>
+
+	* stmt.c (expand_case): Do not create a complex binary tree when
+	optimizing for size but rather use the simple ordered list.
+	(emit_case_nodes): do not emit jumps to the default_label when
+	optimizing for size.
+
+Not regtested so far.
+Comments?
+
+Attached is the test switch.c mentioned below.
