No, spatch just does not find everything it should. Sample below:
--- test.cocci
virtual context

@r depends on context@
{unsigned char, unsigned short int, unsigned int, unsigned long int, unsigned
long long, size_t} v;
@@

*v
--- test.c
void f()
{
    unsigned long ul;
    unsigned long int uli;
    unsigned long long ull;
    unsigned long long int ulli;

    ul;
    uli;
    ull;
    ulli;
}
---
In the example above spatch finds ull, ulli, but not ul and uli.
If you add int to unsigned long long, it won't find anything.

Andrzej
