Well, I wopuld need to have the code for H to do that, since that is
PART of P.
It would begin as:
machine stack stack machine assembly
address address data code language
======== ======== ======== ========= =============
...[00001352][0021233e][00212342] 55 push ebp // enter P
...[00001353][0021233e][00212342] 8bec mov ebp,esp
...[00001355][0021233e][00212342] 8b4508 mov eax,[ebp+08]
...[00001358][0021233a][00001352] 50 push eax // push P
...[00001359][0021233a][00001352] 8b4d08 mov ecx,[ebp+08]
...[0000135c][00212336][00001352] 51 push ecx // push P
...[0000135d][00212332][00001362] e840feffff call 000011a2 // call H
At this point I don't have the data, but it would trace the instructions
that H executes as it simulates its copy of P until it reaches the point
it decides to abort its simulation and return to P
Then it would continue to:
...[00001362][00212332][00001362] 83c408 add esp,+08
...[00001365][0021233a][00001352] 85c0 test eax,eax
...[00001367][0021233a][00001352] 7402 jz 0000136b
...[0000136b][0021233a][00001352] 5d pop ebp
...[0000136c][0021233a][00001352] c3 ret
And P thus Halts.
(Disclaimer, Hand done so typeographical errors may exist)
YOU even have provided the basis of this trace when you published this
equivalent a while back (The trace of H_Hat(H_Hat)
This had the issue that it traces the simulated program that the
simulated H was simulating rather than H itself, but the rest shows what
happens.

Above decision was from the call the Halts inside H_Hat, deciding that
H_Hat(H_Hat) seems to be non-halting, it then returns that answer and is
processed below:
