-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.
