basic_block index negative?


Hija,

I'm heftyly whacking the gcc sources at the moment because of all this
signedness in the sources. Can someone please explain to me how the
index of a basic_block is supposed to become negative? And if not,
how can the return in this snippet

if (then_bb->index < 0)
    return FALSE;

ever be triggered?
