--- Comment #147 from Alexandre Oliva <oliva at gnu.org> ---
in the pseudo code of phase 1, since we're talking about two separate insns, it
would be desirable to make it explicit whether the Ms, Ns, and extc_id that
appear there are taken from previ or from nexti.
I'm also missing code to handle previ.mode == v3.0B_then_16bit. it's
particularly important to specify how the conflict is resolved when nexti is a
10-bit insn: does the return-to-16-bit direction prevail over the M bit in
nexti, or vice-versa, or is that conflict to be rejected?
