llvm dev - Jan 2015 - [LLVMdev] Heads up! Planning to remove old vector shuffle lowering this week...

I'll be skimming the PRs to see if there are any really critical
regressions, but so far it looks pretty good.

If you are actively disabling the new vector shuffling and have some PR
that blocks you, please reply here. Later this week, the flag will go away
unless I hear strenuous objections. There is a really staggering amount of
cleanup and tidying that needs to take place and can't until we remove the
old code paths.

It doesn’t look like there has been any changes for this yet - is the plan for
the old shuffle code to be removed before the branch for 3.6? If so do you have
this in hand or do you want assistance to get it done in time?

I just got distracted by other things. I should be able to take care of it
now that folks are back from the holidays.

One question -- do you see any regressions that need fixing first? I don't
see any, but I'm curious about others. The silence on this thread didn't
inspire confidence, but perhaps its just that nothing is broken with the
new stuff?
