Hi,
According to the schematic
(https://loongson.github.io/LoongArch-Documentation/Loongson-3A5000-usermanual-EN.html#la464-processor-core,
Figure 5) we have 4 ALUs in LA464, but in la464.md we only define
la464_alu1 and la464_alu2.
Should we add la464_alu{3,4} as well, or am I missing something here?

You are right, I just added it before, but I didn't see the performance
improvement,
so I didn't change this place.

Alright, so just left la464.md as-is for now.
I'll try Phoronix bench suite on LoongArch once a binary distro is in a
good shape (Phoronix bench suite uses package managers like apt or dnf
but they are not in Linux From Scratch, and I don't have access to
expensive SPEC CPU suite).
