Semantics for averaging add/sub

Overlapping P and V opcodes

Hi Krste, At the summit, you mentioned that the V opcode space would be extended by using P opcodes since an implementation would not have both P and V. Andes vector cores do have the P extension and

Internal review of Zvfhmin/Zvfh extensions before public review
10 messages
These RISC-V vector extensions to handle IEEE FP16 were defined prior to ratification of the vector specification, but were left out of RVV 1.0 as they were not to be included in the base V extension.
