I already dropped LABEL_NUSES in compact mode in r241120; I think it's
possible to regenerate that information.
But how would we go about recreating the JUMP_LABEL data? As far as I
can tell, it can be set up by reorg.c:make_return_insns
via comparison against function_return_label and
function_simple_return_label, which are set up by find_end_label; the
functions in question are non-trivial, and can lead to extra insns
being emitted. Also, in shrink-wrap.c:handle_simple_exit, which has
similar state considerations.
It seems simpler to serialize this information.
Or am I missing something?
Thanks
Dave
