*	Bug #165: Deletion of unnecessary null pointer checks	Markus Elfring	2014-08-22	1	-11/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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>
