* Reapply an improved version of r180816/180817.Adrian Prantl2013-07-091-0/+45
| | | | | | | | | | | | | | | Change the informal convention of DBG_VALUE machine instructions so that we can express a register-indirect address with an offset of 0. The old convention was that a DBG_VALUE is a register-indirect value if the offset (operand 1) is nonzero. The new convention is that a DBG_VALUE is register-indirect if the first operand is a register and the second operand is an immediate. For plain register values the combination reg, reg is used. MachineInstrBuilder::BuildMI knows how to build the new DBG_VALUES. rdar://problem/13658587 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185966 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an MF argument to MI::copyImplicitOps().Jakob Stoklund Olesen2012-12-201-0/+6
| | | | | | | | | This function is often used to decorate dangling instructions, so a context reference is required to allocate memory for the operands. Also add a corresponding MachineInstrBuilder method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170797 91177308-0d34-0410-b5e6-96231b3b80d8
* Use MachineInstrBuilder in InstrEmitter.Jakob Stoklund Olesen2012-12-201-0/+10
| | | | | | | | | | | | This is supposed to be a mechanical change with no functional effects. InstrEmitter can generate all types of MachineOperands which revealed that MachineInstrBuilder was missing a few methods, added by this patch. Besides providing a context pointer to MI::addOperand(), MachineInstrBuilder seems like a better fit for this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170712 91177308-0d34-0410-b5e6-96231b3b80d8
* Always use addOperand(MF, MO) from MachineInstrBuilder.Jakob Stoklund Olesen2012-12-191-25/+26
| | | | | | The single-argument MachineInstr::addOperand(MO) will be removed soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170599 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the explicit MachineInstrBuilder(MI) constructor.Jakob Stoklund Olesen2012-12-191-1/+0
| | | | | | | | | | | | | Use the version that also takes an MF reference instead. It would technically be possible to extract an MF reference from the MI as MI->getParent()->getParent(), but that would not work for MIs that are not inserted into any basic block. Given the reasonably small number of places this constructor was used at all, I preferred the compile time check to a run time assertion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170588 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an MF argument to MachineInstr::addOperand().Jakob Stoklund Olesen2012-12-191-12/+21
| | | | | | | | | | | | | | | | | | Just like for addMemOperand(), the function pointer provides a context for allocating memory. This will make it possible to use a better memory allocation strategy for the MI operand list, which is currently a slow std::vector. Most calls to addOperand() come from MachineInstrBuilder, so give that class an MF reference as well. Code using BuildMI() won't need changing at all since the MF reference is already required to allocate a MachineInstr. Future patches will fix code that calls MI::addOperand(Op) directly, as well as code that uses the now deprecated MachineInstrBuilder(MI) constructor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170574 91177308-0d34-0410-b5e6-96231b3b80d8
* Express prepend and append in terms of a more generic insert().Jakob Stoklund Olesen2012-12-131-11/+36
| | | | | | | | Also add an MIBundleBuilder constructor that takes an existing bundle. Together these functions make it possible to add instructions to existing bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170063 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a new kind of MachineOperand: MO_TargetIndex.Jakob Stoklund Olesen2012-08-071-0/+6
| | | | | | | | | | | | A target index operand looks a lot like a constant pool reference, but it is completely target-defined. It contains the 8-bit TargetFlags, a 32-bit index, and a 64-bit offset. It is preserved by all code generator passes. TargetIndex operands can be used to carry target-specific information in cases where immediate operands won't suffice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161441 91177308-0d34-0410-b5e6-96231b3b80d8

* Use <def,undef> operands when spilling NEON bundles.Jakob Stoklund Olesen2012-03-041-0/+1
| | | | | | | | | | | MachineOperands that define part of a virtual register must have an <undef> flag if they are not intended as read-modify-write operands. The old trick of adding an <imp-def> operand doesn't work any longer. Fixes PR12177. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152008 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a new kind of MachineOperand: MO_RegisterMask.Jakob Stoklund Olesen2012-01-161-0/+5
| | | | | | | | | | | | | | | | | | | | | Register masks will be used as a compact representation of large clobber lists. Currently, an x86 call instruction has some 40 operands representing call-clobbered registers. That's more than 1kB of useless operands per call site. A register mask operand references a bit mask of call-preserved registers, everything else is clobbered. The bit mask will typically come from TargetRegisterInfo::getCallPreservedMask(). By abandoning ImplicitDefs for call-clobbered registers, it also becomes possible to share call instruction descriptions between calling conventions, and we can get rid of the WINCALL* instructions. This patch introduces the new operand kind. Future patches will add RegMask support to target-independent passes before finally the fixed clobber lists can be removed from call instruction descriptions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148250 91177308-0d34-0410-b5e6-96231b3b80d8

* Improve MachineMemOperand handling.Dan Gohman2009-09-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | 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
