I didn't see similarities between this and the binutils support being upstreamed. For now any implementation would suffice, and I already saw one or two bugs in the output during my TCG host work, but it surely would be nice to switch to generated decoder in the future. The loongarch-opcodes tables could be extended to support peculiarities as exhibited in the v1.00 ISA manual and binutils implementation, via additional attributes, and I'm open to such contributions.
