This will always fail in Objective-C because ObjCMethodDecl does not inherit
from FunctionDecl. Would you add an Objective-C test to ensure this works? If
you're not super familiar with it, the declaration/use syntax should be:
```
#include <stdarg.h>
@interface Foo
-(void)myprintf:(const char *)fmt, ... __attribute__((format(printf, 1, 2)));
-(void)myvprintf:(const char *)fmt list:(va_list)ap
__attribute__((format(printf, 1, 0)));
@end
void bar(Foo *f) {
[f myprintf:"hello %i", 123];
}
void baz(Foo *f, const char *fmt, va_list ap) {
[f myvprintf:fmt list:ap];
}
```
Happy to answer other questions you may have.
