[llvm-commits] CVS: llvm/include/llvm/CodeGen/SelectionDAG.h

[Chris Lattner]

Changes in directory llvm/include/llvm/CodeGen:

SelectionDAG.h updated: 1.136 -> 1.137
---
Log message:

When SimplifySetCC was moved to the DAGCombiner, it was never removed from
SelectionDAG and it has since bitrotted.  Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.

This fixes obscure bugs.
