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

[Chris Lattner]

Changes in directory llvm/lib/CodeGen:

MachineFunction.cpp updated: 1.22 -> 1.23
MachineBasicBlock.cpp (r1.4) removed

---
Log message:

Change MachineBasicBlock's to not be Annotations, instead they are kept as
part of a linked list tracked by MachineFunction.  MachineBasicBlock::get
is now linear time instead of constant time, and thus is deprecated!
