No the only thing that happens automatically is the generation of a rule
for a function prototype when a rule changes something about a function
parameter list.
Also, this idiom is common:
file a.c:
void f(void);
struct ops {
.someop = f;
};
void f(void)
{
}
a(){
b(dev)
}
file b.c:
b(dev)
{
dev->someop();
}
In other words, a is in an indirect fashion calling something it defines.
Have people found a nice way of "hoisting" that call to b() so that it
ends up just being a call to f()? in other words, a.c becomes:
void f(void)
{
}
a()
{
f();
}
This seems quite special purpose. Do you know about the relationship
between a.c and b.c in advance? If so, you can give them both on the
command line and they will be treated as one file. If not you can try
using iteration. See demos/iteration.cocci.
