I'm sure I missed something, I only checked the stats on github, I didn't actually browse all the code to find out where asm was used.
You're right that on a touch screen Android device, emulation is not very attractive. I was thinking more about Android TV boxes (e.g. Minix).
I was also thinking about handheld gaming devices based on ARM9 (e.g. AllWinner) or MIPS (e.g. Ingenic jz47xx), but as far as I know those are all using 32bits CPU cores, so not much chance of porting the 64 bits version to them.
