Changes in directory llvm/lib/Target:
TargetLowering.cpp updated: 1.13 -> 1.14
---
Log message:
Rather than attempting to legalize 1 x float, make sure the SD ISel never
generates it. Make MVT::Vector expand-only, and remove the code in
Legalize that attempts to legalize it.
The plan for supporting N x Type is to continually epxand it in ExpandOp
until it gets down to 2 x Type, where it will be scalarized into a pair of
scalars.
