| |
From: Julia Lawall <julia@diku.dk>
In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test.
The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl> @@ type T; expression E; identifier i,fld; statement S; @@
- T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl>
