Hello,
I was looking to make ``struct thread_info'' opaque again but, noticed this:
thread-db.c contains:
struct private_thread_info
{
/* Cached LWP id. Must come first, see lin-lwp.c. */
lwpid_t lwpid;
};
....
tp = add_thread (ptid);
tp->private = xmalloc (sizeof (struct private_thread_info));
tp->private->lwpid = ti_p->ti_lid;
but no obvious reference to ->private.
Meanwhile, lin-lwp.c contains:
struct private_thread_info
{
int lwpid;
};
....
if (tp->private->lwpid == GET_LWP (lp->ptid))
but no obvious initialization of ->private when adding threads.
It turns out that the main thing keeping this working is that the
lin-lwp.c code is in an unreachable function (find_lwp_callback()).
