Hi Xi,

Thanks for posting this! That's very nice to see.

I'm currently traveling without my laptop (actually in Yunnan, China!),
so I'll be able to take a look at this for real starting the 26th, as
right now I'm just on my cellphone using lore+mutt.

One thing I wanted to ask, though, is - doesn't LoongArch have 32 8-byte
registers? Shouldn't that be enough to implement ChaCha without spilling
and without using LSX?

Jason
