Hi Russell / Nicolas,
thanks for the clarification on ARM history; there's a lot to learn for me about that still.
I'll reply to Rafael regarding state save/restore.

"push" was never an ARM instruction until someone decided to make r13

perfectly good alternative ways to say "push" to the assembler.
