Hi,
The simple cocci rule:
--------
@@
@@
-foo
+bar
--------
Will replace function calls of foo wityh function calls of bar - and as a bonus
it will also update functionpointers to bar.
Unfortunately also other identifiers are matched.
Look at this example:
------------
void foo(int baz)
{
printf("foo %d",baz);
}
void baz(int foo)
{
int bar = 5;
switch (foo) {
case 1 :
break ;
case 2:
foo(2);
printf("two");
break ;
default:
printf("baz %d", bar);
break;
}
}
typedef void (Func)(int);
Func *funclist [] = { foo, baz };
void buh(int bah)
{
(funclist[0])(bah);
(funclist[1])(bah);
}
------------
This will generate this patch:

switch(foo) is changed to switch(bar). Not good. can I avoid this and still get
function pointers updated?
