[PATCH] [LoopVectorize]Teach Loop Vectorizer about interleaved memory access

[Adam Nemet]

Hi Hao,

Thinking about this a bit more, why are we collecting the InterLeaveGroups in LAA?  LAA provides loop dependence information and computing this additional, unrelated information comes at a cost.  Clients other than LV would pay for this without using it.  I think that the InterLeaveGroups analysis should probably live in LV.

What do you think?  Let me know if I am missing something from an earlier discussion.

Adam
