| |
From: Julia Lawall <julia@diku.dk>
The indentation and behavior of the code below suggests that braces are intended around the if branch.
The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl> @r exists@ local idexpression x; statement S; expression E; identifier f,l; position p1,p2; expression *ptr != NULL; @@
( if ((x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...)) == NULL) S | x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S ) <... when != x when != if (...) { <+...x...+> } x->f = E ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; )
@script:python@ p1 << r.p1; p2 << r.p2; @@
print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl>
