Hi.
I have been trying to use spatch to update c struct but haven't found a
way to do so yet.
For example, we have
struct old_thing {
uint8_t a;
uint16_t b[5];
};
which I'd like to replace with
struct new_thing {
uint8_t x1;
uint32_t x2;
uint8_t x3[11];
};
So pretty much replace every function parameter:
f1(... struct old_thing *t...) => f1(... struct new_thing *t...)
Replace the field access and variable definitions:
...
struct old_thing t1; => struct new_thing t1;
struct old_thing *t2; => struct new_thing *t2;
...
t1.a => t1.x1
t2->b => t2->x3
...
The thing which escapes me is how to make coccinelle treat it like a type?
Do I need to use @@typedef struct old_thing@@? Do I use it as
@@identifier old_stuff@@ or @@identifier struct old_stuff@@?
Doesn't seem to work for me.
Any links to .spatch examples playing around with structs would be
greatly appreciated.
