• ARMv8 in RPi4?

    Are the optional aspects of ARMv8, such as
    the AES encryption, in the RPi4?

    Thank-you, Richard.

    I know that I'm a bit of a dinosaur these days, but
    since my baptism in hands-on computing 50 years ago
    this year, assembler on a PDP11/20, my interest is in
    low level control of a processor with no other
    software present and the Pi4 with its 64 bit processing
    and (virtually) unlimited addressing capability
    seems to me to be the answer to a maiden's prayer.

    To that end I'm keen to know after browsing the
    ARMv8 docummentation what other aspects are not
    implemented on the RPi4.

    (Yes, I've touched on this repeatedly in this
    group in the past, but with many other interests,
    it's been a case of putting off today what can
    be put off until tomorrow! :-) )

    The C language, which I have used over many
    years as a real-time embedded softy has certain
    incorrectnesses (wrong precedences between
    logical and relational operations, and the
    stacking of procedure parameters in the wrong
    order to enable printf to work) and part of my
    interest is in language development which
    started in that same 50 year history with the
    formative work leading to SWEPSPEED and CUTLASS
    in the CEGB at Portishead SSD.
