  Can you explain why __umul_tmp1 should not be an "early-clobber output"?

Because it is not written to before we're done with the input.

(I wrote this code close to 30 years ago.  It is stll possible that it
is buggy, but it looks correct to me and it has been in use for a very
long time.  Sure, it is not much used today, as plain 68000 is not in
much use..)
