--- Comment #4 from Robin Dapp <rdapp at gcc dot gnu.org> --- Richard has posted it and asked for reviews. I have tested it and we have several testsuite regressions with it but no severe ones. Most or all of them are dump fails because we combine into vx variants that would be vv variants before. I replied to Richard's post mentioning that we would very much like to see that go in because it helps us generate the code we want. To me it appears very likely that it will land.
