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

[Chris Lattner]

Changes in directory llvm/lib/Transforms/Scalar:

LoopStrengthReduce.cpp updated: 1.74 -> 1.75
---
Log message:

Use SCEVExpander::InsertCastOfTo instead of our own code.  This reduces 
#LLVM LOC, and auto-cse's cast instructions.
