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

cryptography extensions are missing (which is a shame).

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.

Keep the number of passes in a compiler to a minimum. -- D. Gries
