I love it :-)

Back in the distant past I wrote some really big ARM 32 assembly projects. 64 bit ARM is really very similar!

I had a look through the code. Some ENTRY/EXIT macros to help with the drudgery of save restore registers & stack frame would probably help. Also some register renaming would help readability (eg if a register points to incoming data throughout a subroutine rename it pdata).

I salute your effort and please enjoy the core dumps :-)

Thank you! Definitely, some macros would probably be super helpful. Register renaming, too, I'm sure. When I started this project I didn't even know about register renaming lol, and at this point it's so big I'd have to dig pretty deep to find 'em all. Definitely worth doing, though, I'm sure.

RISC OS had some amazing apps written ARM26/32 -- my teenage mind was boggled
