That everyone expects the behavior of the directly
executed DDD to be the same as DDD correctly emulated
by HHH1 is verified as a factually correct expectation.

That everyone expects the behavior of the directly
executed DDD to be the same as DDD correctly emulated
by HHH is verified as a factually incorrect expectation.

It is very common for people to be so well indoctrinated
that they reject verified facts out-of-hand without review.

For the first time in the history of mankind it proves
that a simulation of a virtual machine according to
the semantics of this machine language
DOES NOT ALWAYS HAVE THE SAME BEHAVIOR AS THE DIRECT
EXECUTION OF THIS SAME MACHINE

PATHOLOGICAL SELF REFERENCE DOES CHANGE SEMANTICS

"This sentence is not true"
is neither true nor false because of PSR

This sentence is not true: "This sentence is not true"
The exact same word-for-word sentence
IS TRUE IN THIS DIFFERING CONTEXT THAT DOES NOT HAVE PSR.

The emulator proves the actual behavior specified by the
INPUT INPUT INPUT INPUT INPUT

That people disagree with the semantics of the x86 language
proves how deeply indoctrinated they are.
