[PATCH] D48193: [LoopVectorizer] Use an interleave count of 1 when using a vector library call

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

The register allocator is very constrained on its ability to rematerialize the loads to avoid the spill and reload. It would require the pointers for the address computation to be available on the other side of the call which may require spills/reloads of that register.
