Thu Aug 28 10:10:35 UTC 2014


From: Julia Lawall <Julia.Lawall at lip6.fr>

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier lbl;
identifier rc;
constant c;
@@

- GOTO(lbl,\(rc\|c\));
+ goto lbl;

@@
identifier lbl;
expression rc;
@@

- GOTO(lbl,rc);
+ rc;
+ goto lbl;
// </smpl>

Signed-off-by: Julia Lawall <Julia.Lawall at lip6.fr>

---
This should be applied after the return-parenthesis patch.
