| |
From: Julia Lawall <julia@diku.dk>
The variable num_group_tail_writes is initialized but never used otherwise.
The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl> @@ type T; identifier i; constant C; @@
( extern T i; | - T i; <+... when != i - i = C; ...+> ) // </smpl>
