reload problem:

[dimmy]

Well, for the code given

int *a, b;

void foo()
{
    b -= *a;
}

I'll get:

    mov &a, r12
    sub @r12, &b    <-- this is _2 pattern. zero_shifted() and 
indexed_location() both true.

the code will be exactly the same with no to highest optimization option.

Anyway, thanks.
It works now.

cheers,
Dmitry.
