This solves my problem, but maybe creates one for Alibaba. They have apparently fabbed a chip using the 0.7.1 draft of the vector spec proposal. So for qemu to properly support their asic, the 0.7.1 draft support will have to be retained. But I think SiFive and everyone else is waiting for the official spec before building asics with vector support. If Alibaba will update their processor as the spec evolves, then maybe this isn't a problem for them. Jim
