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

[Chris Lattner]

Changes in directory llvm/include/llvm/CodeGen:

SelectionDAGISel.h updated: 1.28 -> 1.29
---
Log message:

Generalize CaseBlock a bit more:

Rename LHSBB/RHSBB to TrueBB/FalseBB.  Allow the RHS value to be null,
in which case the LHS is treated as a bool.
