[llvm-commits] CVS: llvm/lib/Transforms/Scalar/InstructionCombining.cpp

[Reid Spencer]

Changes in directory llvm/lib/Transforms/Scalar:

InstructionCombining.cpp updated: 1.570 -> 1.571
---
Log message:

Convert the last uses of CastInst::createInferredCast to a normal cast
creation. These changes are still temporary but at least this pushes 
knowledge of signedness out closer to where it can be determined properly
and allows signedness to be removed from VMCore.

Diffs of the changes:  (+10 -3)
