[llvm-commits] CVS: llvm/lib/CodeGen/MachineBasicBlock.cpp

[Brian Gaeke]

Changes in directory llvm/lib/CodeGen:

MachineBasicBlock.cpp updated: 1.9 -> 1.10

---
Log message:

Add non-const MachineBasicBlock::getParent() accessor method.

MBBs start out as #-1. When a MBB is added to a MachineFunction, it
gets the next available unique MBB number. If it is removed from a
MachineFunction, it goes back to being #-1.
