| |
From: Julia Lawall <julia@diku.dk>
fcf is tested in the line just below, so the first test is not needed.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @r@ expression *x; expression e; identifier l; @@
if (x == NULL || ...) { ... when forall return ...; } ... when != goto l; when != x = e when != &x *x == NULL // </smpl>
