| |
From: Julia Lawall <Julia.Lawall@lip6.fr>
Delete a variable that is at most only assigned to a constant, but never used otherwise.
A simplified version of the semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ type T; identifier i; constant c; @@
-T i; <... when != i -i = c; ...> // </smpl>
