Changes in directory llvm/lib/Target:
TargetData.cpp updated: 1.58 -> 1.59
---
Log message:
TargetData.cpp::getTypeInfo() was returning alignment of element type as the
alignment of a packed type. This is obviously wrong. Added a workaround that
returns the size of the packed type as its alignment. The correct fix would
be to return a target dependent alignment value provided via TargetLowering
(or some other interface).
