Subject: [Cocci] Changing function pointer typedef
Date: Fri, 8 Mar 2019 13:19:55 -0500	[thread overview]
Message-ID: <20190308181954.GB5618@redhat.com> (raw)

Coccinelle seems to have issue with function pointer. For instance
if i want to add a new argument to a function pointer typdef i need
to replace the whole typedef as one line. For instance:

test.c:
typedef int (*filler_t)(void *, struct page *);

test.spatch:
@@
type T1, T2;
@@
-typedef int (*filler_t)(T1, T2);
+typedef int (*filler_t)(T1, struct address_space *, T2);

Anything else will not work and also if the function pointer typedef
spread accross multiple line then the above does not work, in fact
i have not found a work around for that case.

I am missing some syntax that make this work with coccinelle ?

Cheers,
Jérôme
