This hasn't been tested much at all; I need to either get FVP up and running for RISU comparison, or write some stand-alone test cases. But in the meantime this could use some eyes. SME2 is the first vector-like extension we've had that has dynamic indexing of registers: ZArray[(rv + offset) % svl], where RV is a general register. So the first thing I do is extend TCG's gvec support to handle TCGv_ptr base + offset addressing. I only changed enough to handle what I needed within SME2; changing it all would be a big job, and it would (at least for the moment) remain unused. Still to-do are few more extensions for SME2p1.
Ho hum. I've missed the entire set of counted predicate insns. Hooray for Arm sample code! r~
