[llvm-commits] CVS: llvm/include/llvm/Instructions.h

[Nate Begeman]

Changes in directory llvm/include/llvm:

Instructions.h updated: 1.24 -> 1.25
---
Log message:

Fix a fixme in CondPropagate.cpp by moving a PhiNode optimization into
BasicBlock's removePredecessor routine.  This requires shuffling around
the definition and implementation of hasContantValue from Utils.h,cpp into
Instructions.h,cpp
