| |
From: Julia Lawall <julia@diku.dk>
The pattern !E && !E->fld is nonsensical. The patch below updates this according to the assumption that && should be ||. But perhaps another solution was intended.
The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl> @disable and_comm@ expression E; identifier fld; @@
- !E && !E->fld + !E || !E->fld // </smpl>
