--- Comment #6 from Ian Lance Taylor <ian at airs dot com> --- libgo is running behind right now, but in any case I personally don't have plans to add LoongARCH support. I would be happy to review any patches, which would ideally be sent using the process described at https://go.dev/doc/gccgo_contribute.
