Update the semantic patches to use new development ideas Co-Authored-By: Markus Elfring <Markus.Elfring@web.de> 2025-10-08 11:03:18 -04:00			`@rule1@`
Add semantic patch to find void f() { ... return ((void)g())); ... } When a function returns void, it can be used as an argument to return in function returning also void, e.g.: void in(void) { return; } void out(void) { return (in()); } while this is legal, it should be rewritten as: void out(void) { in(); return; } The semantic patch just find the occurrences, and they need to be fixed by hand. 2019-12-06 07:29:04 -05:00			`identifier f1;`
