Is it just me, or … (ARMARMs)

Probably just me, but …

When using the ARM ARMs, do you find that, even if using them to look up stuff for ‘modern” ARM32 (ARMv8 AARCH32), some are more useful than others?

I have them all in a reference folder. I am working with the RISC OS 5 source code, and, for example,

(condition codes encoding / relation to NZCV, and dataproc opcodes) : ARMARM (ARM610)

(ARM instruction set encoding) : ARMARMv4 for ‘classic’ ARM32, and ARMARMv6 for ‘next gen’ ARM32

(shifter carryout from shifter operands) : ARMARMv3 (ARM610) has the best explanation by far

(finer details of flag changes from operand2, and core instructions) : ARMARMv4

while I need to use ARMARMv8 / ARMARMv7 too, the older ones save a lot of time!)

All documentation is horrible.

Except the PostScript Red Book.
