[llvm-commits] CVS: llvm/lib/Target/PowerPC/PPCISelDAGToDAG.cpp PPCISelLowering.cpp PPCISelLowering.h

[Dan Gohman]

Changes in directory llvm/lib/Target/PowerPC:

PPCISelDAGToDAG.cpp updated: 1.230 -> 1.231
PPCISelLowering.cpp updated: 1.274 -> 1.275
PPCISelLowering.h updated: 1.65 -> 1.66
---
Log message:

Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits from
TargetLowering to SelectionDAG so that they have more convenient
access to the current DAG, in preparation for the ValueType routines
being changed from standalone functions to members of SelectionDAG for
the pre-legalize vector type changes.
