[llvm-commits] CVS: llvm/include/llvm/Analysis/ProfileInfo.h

[Chris Lattner]

Changes in directory llvm/include/llvm/Analysis:

ProfileInfo.h updated: 1.2 -> 1.3

---
Log message:

We don't want to make this a pure interface, as it makes all implementors
bear the burden of implementing what will be all exactly the same methods.
They just want to provide the information in differing ways.
