2008-09-23Now that DeadMachineInstructionElim is basically workingDan Gohman
correctly, it's not necessary to explicitly remove registers from their use-def lists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-23Arrange for FastISel code to have access to the MachineModuleInfoDan Gohman
object. This will be needed to support debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56508 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-23Track local physical register liveness. This is not the mostDan Gohman
efficient implementation possible, but it's pretty simple and good enough for the time being. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56504 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-23Replace the LiveRegs SmallSet with a simple counter that keepsDan Gohman
track of the number of live registers, which is all the set was being used for. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56498 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-23Fix these enums' starting values to reflect the way thatDan Gohman
instruction opcodes are now numbered. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56497 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-23Move the code for initializing the global base reg out ofDan Gohman
X86ISelDAGToDAG.cpp and into X86InstrInfo.cpp. This will allow it to be reused by FastISel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56494 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-22Significant improvements to the logic for merging live intervals. This code ↵Owen Anderson
