btw, for clarification of anyone who is confused by the names...the new
architecture is ARMv8. The 64-bit state is AArch64, during which the
processor executes A64 instructions. The 32-bit state is AArch32, during
which the processor executes either A32 ("ARM" version 7+) or T32
("Thumb" - I guess Thumb2+ really due to some of deprecation)
instructions. I've noticed that there appears to be a clarification
effort in which AArch64 is used as an architecture name when ARMv8 would
be confusing, which is most of the time if you don't know whether you're
referring to the new A64 instruction set or the older ones.
Perhaps this is useful if someone is trying to figure out heads or tails
of the different terms.
Jon.
