Misleading words when you change the meaning of diverging.
Mike showed the traces side by side. Even after many requests, you
still cannot show the first instruction that is interpreted differently
by HHH and HHH1. The only difference is that HHH gives up the
simulation too early.

Yes, that is exactly the point where HHH aborts.

Both the divergence and the abort are shown below.

The question is incorrect.
HHH emulates DDD two times and HHH1 emulates DDD one time
the whole second time is the divergence.

There is no divergence if the instructions are emulated exactly the same in both cases.

 HHH1(DDD) emulates DDD exactly one time.
HHH(DDD) emulates DDD exactly two times.
 The whole second time that HHH emulates DDD is
divergence.
 

Let the record show that Peter Olcott has failed to identify an instruction that HHH and HHH1 emulated differently.

>

What happened before either emulation started is irrelevant.
 The only way for the emulations to diverge is if there is a particular instruction such that X happens if HHH emulates it and Y happens if HHH1 emulates it.  Again, what happened before either emulation started is irrelevant.
  So I'll ask one more time:  how exactly do HHH and HHH1 emulate the first instruction of HHH, or *any* instruction that is part of the emulation of DDD, differently?
 Failure to provide the above explanation in your next reply or within
one hour of your next post in this newsgroup will be taken as your
official on-the-record admission that the emulations of DDD performed
by HHH and HHH1 do *not* diverge but are in fact the same up to the
point that HHH aborts.

Therefore, as per the above criteria:
Let The Record Show
That Peter Olcott
Has *officially* admitted:
That the emulations of DDD by HHH and HHH1 in fact do *not* diverge but are in fact the same up to the point that HHH aborts.
