One note (still like this in bpl21) is that in do_gen_tog,
    long result;
should be
    bitvector_t result;

If you have more than 32 PRF flags, it'll mess up on 'em.

Also, I found it a little easier just to define a macro in utils.h
#define BIT(x) (1LL << x)
just for readability mostly, but it does look better, ie:

#define PRF_ONETHING BIT(32)
#define PRF_TWOTHING BIT(33)
