* Enable rematerialization of constants using ↵Dan Gohman2008-07-251-0/+8
| | | | | | | | | | | AliasAnalysis::pointsToConstantMemory, and knowledge of PseudoSourceValues. This unfortunately isn't sufficient to allow constants to be rematerialized in PIC mode -- the extra indirection is a complication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54000 91177308-0d34-0410-b5e6-96231b3b80d8

* provide def_* and use_* iterators in addition to reg_* iterators.Chris Lattner2008-01-101-12/+51

* switch the register iterator to act more like hte LLVM value iterator: ↵Chris Lattner2008-01-011-8/+26
| | | | | | | | | | | | dereferencing it now returns the machineinstr of the use. To get the operand, use I.getOperand(). Add a new MachineRegisterInfo::replaceRegWith, which is basically like Value::replaceAllUsesWith. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45482 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | operands. The lists are currently kept in MachineRegisterInfo, but it does not yet provide an iterator interface to them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45477 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-0/+118
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45467 91177308-0d34-0410-b5e6-96231b3b80d8
