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.
Perhaps it would be easiest to re-use the decodetree description?
See e.g. target/openrisc/disas.c.
Indeed; I didn't thought of disassemblers in target/ instead of disas/. That would be the
most elegant way forward!
The one quirk will be that so far using decodetree for disas is limited to the target,
whereas you'll want this for host as well. It shouldn't be a big deal, just a small
matter of the correct build rules.
