| |
Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit.
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>
