Yes, find_synth_field() is used only once and is short, so I can just
add that into synth_event_add_val() directly. And looking at
synth_event_add_val() and synth_event_add_next_val(), they're almost
identical and so can be made into a single function with a param for
the different parts (but still need to be exported separately so they
can be used with the piecewise API).
It would also be possible to have synth_event_trace() and
synth_event_trace_array() use synth_event_add_next_val() instead of
writing the fields directly but that would be more overhead for those
functions, which is why I avoided doing that.
Let me know if it's something else you're referring to, or if you want
me to do a v5 or a follow-on patch to do the first part above.
Thanks,
Tom
