Drop static on a local variable, when the variable is initialized before any use on every possible execution path through the function. The static has no benefit, and dropping it reduces the code size. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> The change in code size is indicates by the following output from the size command. before: text data bss dec hex filename 835 80 8 923 39b drivers/mtd/maps/physmap_of_gemini.o after: text data bss dec hex filename 823 80 0 903 387 drivers/mtd/maps/physmap_of_gemini.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Brian Norris <computersforpeace@gmail.com> |
