2009-08-23remove various std::ostream version of printing methods fromChris Lattner
MachineInstr and MachineOperand. This required eliminating a bunch of stuff that was using DOUT, I hope that bill doesn't mind me stealing his fun. ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79813 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-30Add a bit IsUndef to MachineOperand. This indicates the def / use register ↵Evan Cheng
operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them. The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing. This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74518 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-18Teach DAGCombine to fold constant offsets into GlobalAddress nodes,Dan Gohman
and add a TargetLowering hook for it to use to determine when this is legal (i.e. not in PIC mode, etc.) This allows instruction selection to emit folded constant offsets in more cases, such as the included testcase, eliminating the need for explicit arithmetic instructions. This eliminates the need for the C++ code in X86ISelDAGToDAG.cpp that attempted to achieve the same effect, but wasn't as effective. Also, fix handling of offsets in GlobalAddressSDNodes in several places, including changing GlobalAddressSDNode's offset from int to int64_t. The Mips, Alpha, Sparc, and CellSPU targets appear to be unaware of GlobalAddress offsets currently, so set the hook to false on those targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57748 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-03Switch the MachineOperand accessors back to the short names likeDan Gohman
isReg, etc., from isRegister, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57006 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-24Next round of earlyclobber handling. Approach theDale Johannesen
RA problem by expanding the live interval of an earlyclobber def back one slot. Remove overlap-earlyclobber throughout. Remove earlyclobber bits and their handling from live internals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56539 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-17Add a bit to mark operands of asm's that conflictDale Johannesen
with an earlyclobber operand elsewhere. Propagate this bit and the earlyclobber bit through SDISel. Change linear-scan RA not to allocate regs in a way that conflicts with an earlyclobber. See also comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56290 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-13Remove isImm(), isReg(), and friends, in favor of Dan Gohman
isImmediate(), isRegister(), and friends, to avoid confusion about having two different names with the same meaning. I'm not attached to the longer names, and would be ok with changing to the shorter names if others prefer it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56189 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-12Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* andDan Gohman
ConstantFP* instead of APInt and APFloat directly. This reduces the amount of time to create ConstantSDNode and ConstantFPSDNode nodes when ConstantInt* and ConstantFP* respectively are already available, as is the case in SelectionDAGBuild.cpp. Also, it reduces the amount of time to legalize constants into constant pools, and the amount of time to add ConstantFP operands to MachineInstrs, due to eliminating ConstantInt::get and ConstantFP::get calls. It increases the amount of work needed to create new constants in cases where the client doesn't already have a ConstantInt* or ConstantFP*, such as legalize expanding 64-bit integer constants to 32-bit constants. And it adds a layer of indirection for the accessor methods. But these appear to be outweight by the benefits in most cases. It will also make it easier to make ConstantSDNode and ConstantFPNode more consistent with ConstantInt and ConstantFP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56162 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-12Pass "earlyclobber" bit through to machineDale Johannesen
representation; coalescer and RA need to know about it. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56161 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
2007-12-30Add new shorter predicates for testing machine operands for various types: Chris Lattner
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
2007-12-30- rename opType -> OpKind and contents -> Contents.Chris Lattner
- eliminate the auxInfo union, merging it into the contents union. This shaves 4 bytes off MachineOperand on a 32-bit machine. - Use accessors in ctor methods. - Add comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45462 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-30More cleanups for MachineOperand:Chris Lattner
- 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
2007-12-30MachineOperand:Chris Lattner
- 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
