That's right, it's not implemented yet. The work-around is to use
ucontext. uc_mcontext contains the trapframe which has tf_err
(uc.uc_mcontext.mc_tf.tf_err).
I haven't paid any attention to implement any of the fields in siginfo_t
because that may only have complicated matters. It may be required to do
some non-trivial rewriting to get all the information at the right
place. Since real-time signals are also in the pipeline and also may
have specific needs, both "problems" can best be considered at the same
time (IMO).
