I'm thinking of adding ARMv4 (not v4T) support, so I can test that
code needing to run on a real ARMv4 does not accidentally have any
unsupported instructions.
While looking into that, I found it quite difficult to find which
instructions are supported by different ARM architecture levels, and
especially how PC is treated by different instructions on the
different architectures.
Do you know of a good summary reference which lists which instructions
are available in each ARM architecture level from ARMv4 up to ARMv7
and it's variants?
(Preferably without an ARM licensing agreement or NDA).
