Re: [Qemu-devel] [PATCH v6 00/26] tcg: generic vector operations

[Timothy Pearson]

Just as a note, I've been watching these series with great interest.
Once the changes settle down / are mergeable we will be looking to
implement vector <--> vector support between a couple of other
architectures.

Thanks for working on this!
