* Bug #165: Deletion of unnecessary null pointer checksMarkus Elfring2014-08-223-19/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function "free" performs input parameter validation. http://pubs.opengroup.org/onlinepubs/9699919799/functions/free.html It is therefore not needed to check a passed pointer before this function call. A corresponding update suggestion was generated by the software "Coccinelle" from the following semantic patch approach. http://coccinelle.lip6.fr/ @Remove_unnecessary_pointer_checks1@ expression x; @@ -if (x != \(0 \| NULL\)) free(x); @Remove_unnecessary_pointer_checks2@ expression x; @@ -if (x != \(0 \| NULL\)) { free(x); x = \(0 \| NULL\); -} @Remove_unnecessary_pointer_checks3@ expression a, b; @@ -if (a != \(0 \| NULL\) && b != \(0 \| NULL\)) +if (a) free(b); @Remove_unnecessary_pointer_checks4@ expression a, b; @@ -if (a != \(0 \| NULL\) && b != \(0 \| NULL\)) { +if (a) { free(b); b = \(0 \| NULL\); } Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
