* remove #includageChris Lattner2008-01-071-1/+1
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45697 91177308-0d34-0410-b5e6-96231b3b80d8
* rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner2008-01-071-13/+13
| | | | | | | | Make MachineInstr::getDesc return a reference instead of a pointer, since it can never be null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45695 91177308-0d34-0410-b5e6-96231b3b80d8
* rename hasVariableOperands() -> isVariadic(). Add some comments.Chris Lattner2008-01-071-3/+2
| | | | | | | | Evan, please review the comments I added to getNumDefs to make sure that they are accurate, thx. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45687 91177308-0d34-0410-b5e6-96231b3b80d8
* Move a bunch more accessors from TargetInstrInfo to TargetInstrDescriptorChris Lattner2008-01-071-12/+12

* Add predicates methods to TargetOperandInfo, and switch all clients Chris Lattner2008-01-071-2/+2
| | | | | | | | over to using them, instead of diddling Flags directly. Change the various flags from const variables to enums. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45677 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner2008-01-071-7/+7
| | | | | | | | | | | | | | | | | | that it is cheap and efficient to get. Move a variety of predicates from TargetInstrInfo into TargetInstrDescriptor, which makes it much easier to query a predicate when you don't have TII around. Now you can use MI->getDesc()->isBranch() instead of going through TII, and this is much more efficient anyway. Not all of the predicates have been moved over yet. Update old code that used MI->getInstrDescriptor()->Flags to use the new predicates in many places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45674 91177308-0d34-0410-b5e6-96231b3b80d8
* Make MachineRegisterInfo::getVRegDef more efficient by aiming the keep the ↵Chris Lattner2008-01-011-4/+10
| | | | | | def of the vreg at the start of the list, so the list doesn't need to be traversed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45483 91177308-0d34-0410-b5e6-96231b3b80d8
* switch the register iterator to act more like hte LLVM value iterator: ↵Chris Lattner2008-01-011-1/+1
| | | | | | | | | | | | 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
* Implement automatically updated def/use lists for all MachineInstr register Chris Lattner2008-01-011-3/+249
| | | | | | | | 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
* properly encapsulate the parent field of MBB and MI with get/set accessors.Chris Lattner2007-12-311-6/+6
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45469 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-0/+1
| | | | | | | | | | | | | | | | 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
* Add new shorter predicates for testing machine operands for various types: Chris Lattner2007-12-301-9/+8
| | | | | | | | | | | | | | e.g. MO.isMBB() instead of MO.isMachineBasicBlock(). I don't plan on switching everything over, so new clients should just start using the shorter names. Remove old long accessors, switching everything over to use the short accessor: getMachineBasicBlock() -> getMBB(), getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45464 91177308-0d34-0410-b5e6-96231b3b80d8
* More cleanups for MachineOperand:Chris Lattner2007-12-301-110/+114
| | | | | | | | | | | - Eliminate the static "print" method for operands, moving it into MachineOperand::print. - Change various set* methods for register flags to take a bool for the value to set it to. Remove unset* methods. - Group methods more logically by operand flavor in MachineOperand.h git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45461 91177308-0d34-0410-b5e6-96231b3b80d8
* MachineOperand:Chris Lattner2007-12-301-57/+38
| | | | | | | | | | | | | | | | | | | - Add getParent() accessors. - Move SubReg out of the AuxInfo union, to make way for future changes. - Remove the getImmedValue/setImmedValue methods. - in some MachineOperand::Create* methods, stop initializing fields that are dead. MachineInstr: - Delete one copy of the MachineInstr printing code, now there is only one dump format and one copy of the code. - Make MachineOperand use the parent field to get info about preg register names if no target info is otherwise available. - Move def/use/kill/dead flag printing to the machineoperand printer, so they are always printed for an operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45460 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up sub-register implementation by moving subReg information back toEvan Cheng2007-11-141-0/+2
| | | | | | | | | | | | MachineOperand auxInfo. Previous clunky implementation uses an external map to track sub-register uses. That works because register allocator uses a new virtual register for each spilled use. With interval splitting (coming soon), we may have multiple uses of the same register some of which are of using different sub-registers from others. It's too fragile to constantly update the information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44104 91177308-0d34-0410-b5e6-96231b3b80d8

* EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG likeEvan Cheng2007-10-121-0/+18
| | | | | | | | | | (almost) a register copy. However, it always coalesced to the register of the RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub- register uses which adds subtle complications to load folding, spiller rewrite, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42899 91177308-0d34-0410-b5e6-96231b3b80d8
