9 The attached patch makes sure that we create smaller object code for
10 simple switch statements. We just make sure to flatten the switch
11 statement into an if-else chain, basically.
13 This fixes a size-regression as compared to gcc-3.4, as can be seen
16 2007-04-15 Bernhard Fischer <..>
18 * stmt.c (expand_case): Do not create a complex binary tree when
19 optimizing for size but rather use the simple ordered list.
20 (emit_case_nodes): do not emit jumps to the default_label when
26 Attached is the test switch.c mentioned below.
