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

[Chris Lattner]

Changes in directory llvm/include/llvm/CodeGen:

MachineBasicBlock.h updated: 1.7 -> 1.8
MachineFunction.h updated: 1.12 -> 1.13

---
Log message:

Add BasicBlock list to MchineFunction that will eventually be the only
way to access MachineBasicBlocks.  For now, it is never filled.
