    HHH is an emulating termination analyzer that emulates
    the x86 machine code located at the address of a function
    using a fully functional x86 emulator.

    When HHH recognizes a non-terminating pattern in the
    execution trace of its emulated input it aborts this
    emulation and returns 0.

    typedef void (*ptr)();
    int HHH(ptr P);

    I challenged everyone here to provide the machine address
    by machine address (AKA line by line) execution trace
    of DD correctly emulated by HHH that reaches its own
    "ret" instruction.

    Olcott could as well challenge everyone to draw a correct square circle.


    No one made any attempt to do this because they know that
    this would prove that they are stupidly wrong to say that
    my trace is incorrect.


    No one will attempt to draw a square circle. Does that imply that it is wrong to say that another failed attempt to draw a square circle is incorrect?

    Similarly, HHH cannot possibly simulate itself correctly.

    This C code conclusively proves that HHH does correctly
    emulate self emulating DD correctly. https://github.com/plolcott/x86utm/blob/master/Halt7.c

    That you lack the technical capability to understand
    that code is far less than no actual rebuttal at all.

    Olcott's HHH
    is incorrect, but a correct HHH that simulates itself does not exist. Therefore, it is very stupid to challenge everyone to correct HHH.
