Changes in directory llvm/lib/CodeGen/SelectionDAG:
LegalizeDAG.cpp updated: 1.344 -> 1.345
---
Log message:
Scalarized vector stores need not be legal, e.g. if the vector element type
needs to be promoted or expanded. Relegalize the scalar store once created.
This fixes CodeGen/Generic/vector.ll:test1 on non-SSE x86 targets.
