Currently we can handle 10 SVE opcodes (out of 314) in the codec. Now that we are preparing to implement the rest of SVE, the notion of a variable vector...

Thanks for the detailed answer @derekbruening. > But, at least in our usage, it seems rare to run two separate DR clients at once: do you end up doing that?...
