...hronization in such a critical datastructure would be badness... That said, I don't know just how horrible the impact is on the code. Maybe there is another way? Maybe the value table should be a first class datastructure that SelectionDAG contains. This would let you do things like: SD.getValueTable().getNumVectorElements(VT) but it would also allow clients to grab a reference to the valuetable and call into it directly if more convenient. Would this help at all? One nice thing about this is that the ValueTable datastructure would be very simple, and moving all the methods to operate...

Hello, Here's a quick update on where I'm at with the pre-legalize vector changes I'm working on. I hope to have an updated patch ready to a few days, assuming I don't get too busy with other projects going on. Here are some of the issues I've come across so far. Putting the table for extended ValueTypes in SelectionDAG seems quite involved. There are a lot of places that use
