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

[Misha Brukman]

Changes in directory llvm/include/llvm/CodeGen:

SSARegMap.h added (r1.1)
MachineFunction.h updated: 1.19 -> 1.20

---
Log message:

SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.
