[llvm-commits] CVS: llvm/include/llvm/Target/MRegisterInfo.h

[Alkis Evlogimenos]

Changes in directory llvm/include/llvm/Target:

MRegisterInfo.h updated: 1.28 -> 1.29

---
Log message:

Change MachineBasicBlock's vector of MachineInstr pointers into an
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.
