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

[Dan Gohman]

Changes in directory llvm/lib/Transforms/Scalar:

LoopStrengthReduce.cpp updated: 1.135 -> 1.136
---
Log message:

Use IntrinsicInst to test for prefetch instructions, which is ever so
slightly nicer than using CallInst with an extra check; thanks Chris.
