...vector lengths, which is needed by us. We needed to add v3f32 and v3i32 ValueTypes just to define our register file in the .td. -- Christopher Lamb -------------- next part -------------- An HTML attachment was scrubbed...

After doing a bunch of work for moving pre-legalize extended ValueTypes into a table in SelectionDAG, I may have just found a simpler approach. There are under 32 simple ValueType values, so we only really need 5 bits to represent those. ValueType is already a 32-bit type on most hosts; what if we make use of the remaining 27 bits instead of using an external table? If we can assume that vector
