* Implement automatically updated def/use lists for all MachineInstr register Chris Lattner2008-01-011-1/+27
| | | | | | | operands. The lists are currently kept in MachineRegisterInfo, but it does not yet provide an iterator interface to them. llvm-svn: 45477
* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-0/+20
that "machine" classes are used to represent the current state of the code being compiled. Given this expanded name, we can start moving other stuff into it. For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from MachineFunction into it. Update all the clients to match. This also reduces some needless #includes, such as MachineModuleInfo from MachineFunction. llvm-svn: 45467
