// the next bb isn't found in the fast-cache; or if the current bb
|
|
// exited with a request for some special action before continuing; or
|
|
// if the current thread has used up its scheduling quantum.

/* Run translations, with the given guest state, and starting by
|
|
running the host code at 'host_addr'. It is almost always the case
|
|
that host_addr is the translation for guest_state.guest_IP, that
|
|
is, host_addr is what it would be if we looked up the address of
|
|
the translation corresponding to guest_state.guest_IP.
|
|
|
|
The only case where this isn't true is where we're running a
|
|
no-redir translation. In this case host_addr is the address of the
|
|
alternative (non-redirected) translation for guest_state.guest_IP.
|
|
|
|
The return value must indicate why it returned back to the scheduler.
|
|
It can also be exited if the executing code throws a non-resumable
|
|
signal, for example SIGSEGV, in which case control longjmp()s back past
|
|
here.
|
|
|
|
two_words holds the return values (two words). First is
|
|
a TRC value. Second is generally unused, except in the case
|
|
where we have to return a chain-me request.
