Detailed Description

Representation of each machine instruction.

This class isn't a POD type, but it must have a trivial destructor. When a MachineFunction is deleted, all the contained MachineInstrs are deallocated without having their destructor called.

Member Function Documentation

void MachineInstr::addMemOperand ( MachineFunction MF,
MachineMemOperand MO 
)

Add a MachineMemOperand to the machine instruction.

addMemOperand - Add a MachineMemOperand to the machine instruction.

This function should be used only occasionally. The setMemRefs function is the primary method for setting up a MachineInstr's MemRefs list.

Definition at line 829 of file MachineInstr.cpp.

References llvm::MachineFunction::allocateMemRefsArray().

Referenced by llvm::MachineInstrBuilder::addMemOperand(), llvm::TargetLoweringBase::emitPatchPoint(), llvm::TargetInstrInfo::foldMemoryOperand(), llvm::PPCInstrInfo::loadRegFromStackSlot(), and llvm::PPCInstrInfo::storeRegToStackSlot().

void MachineInstr::addOperand ( MachineFunction MF,
const MachineOperand Op 
)

Add the specified operand to the instruction.

addOperand - Add the specified operand to the instruction.

If it is an implicit operand, it is added to the end of the operand list. If it is an explicit operand it is added at the end of the explicit operand list (before the first implicit operand).

MF must be the machine function that was used to allocate this instruction.

MachineInstrBuilder provides a more convenient interface for creating instructions and adding operands.

If it is an implicit operand, it is added to the end of the operand list. If it is an explicit operand it is added at the end of the explicit operand list (before the first implicit operand).

void MachineInstr::addOperand ( const MachineOperand Op)

This only works for instructions that are inserted in a basic block.

MachineInstrBuilder and the two-argument addOperand(MF, MO) should be preferred.

bool llvm::MachineInstr::canFoldAsLoad ( QueryType  Type = IgnoreBundle) const
inline

Return true for instructions that can be folded as memory operands in other instructions.

The most common use for this is instructions that are simple loads from memory that don't modify the loaded value in any way, but it can also be used for instructions that can be expressed as constant-pool loads, such as V_SETALLONES on x86, to allow them to be folded when it is beneficial. This should only be set on instructions that return a value in their only virtual register definition.

Unlink 'this' form its basic block and delete it.

If the instruction is part of a bundle, the other instructions in the bundle remain bundled.

void MachineInstr::eraseFromParent ( )

Unlink 'this' from the containing basic block and delete it.

If this instruction is the header of a bundle, the whole bundle is erased. This function can not be used for instructions inside a bundle, use eraseFromBundle() to erase individual bundled instructions.

int MachineInstr::findFirstPredOperandIdx ( ) const
int MachineInstr::findInlineAsmFlagIdx ( unsigned  OpIdx,

Find the index of the flag word operand that corresponds to operand OpIdx on an inline asm instruction.

Returns -1 if getOperand(OpIdx) does not belong to an inline asm operand group.

If GroupNo is not NULL, it will receive the number of the operand group containing OpIdx.

The flag operand is an immediate that can be decoded with methods like InlineAsm::hasRegClassConstraint().

Returns the operand index that is a def of the specified register or -1 if it is not found.

findRegisterDefOperandIdx() - Returns the operand index that is a def of the specified register or -1 if it is not found.

If isDead is true, defs that are not dead are skipped. If Overlap is true, then it also looks for defs that merely overlap the specified register. If TargetRegisterInfo is non-null, then it also checks if there is a def of a super-register. This may also return a register mask operand when Overlap is true.

If isDead is true, defs that are not dead are skipped. If TargetRegisterInfo is non-null, then it also checks if there is a def of a super-register.

const TargetRegisterClass * MachineInstr::getRegClassConstraint ( unsigned  OpIdx,

Compute the static register class constraint for operand OpIdx.

For normal instructions, this is derived from the MCInstrDesc. For inline assembly it is derived from the flag words.

Returns NULL if the static register class constraint cannot be determined.

Applies the constraints (def/use) implied by the OpIdx operand to the given CurRC.

Returns the register class that satisfies both CurRC and the constraints set by OpIdx MI. Returns NULL if such a register class does not exist.

Precondition
CurRC must not be NULL.
The operand at OpIdx must be a register.

Applies the constraints (def/use) implied by this MI on Reg to the given CurRC.

If ExploreBundle is set and MI is part of a bundle, all the instructions inside the bundle will be taken into account. In other words, this method accumulates all the constraints of the operand of this MI and the related bundle if MI is a bundle or inside a bundle.

Returns the register class that satisfies both CurRC and the constraints set by MI. Returns NULL if such a register class does not exist.

CurRC must not be NULL.

bool llvm::MachineInstr::isConvertibleTo3Addr ( QueryType  Type = IgnoreBundle) const
inline

Return true if this is a 2-address instruction which can be changed into a 3-address instruction if needed.

Doing this transformation can be profitable in the register allocator, because it means that the instruction can use a 2-address form if possible, but degrade into a less efficient form if the source and dest register cannot be assigned to the same register. For example, this allows the x86 backend to turn a "shl reg, 3" instruction into an LEA instruction, which is the same speed as the shift but has bigger code size.

If this returns true, then the target must implement the TargetInstrInfo::convertToThreeAddress method for this instruction, which is allowed to fail if the transformation isn't valid for this specific instruction (e.g. shl reg, 4 on x86).

bool llvm::MachineInstr::readsVirtualRegister ( unsigned  Reg) const

Return true if the MachineInstr reads the specified virtual register.

Take into account that a partial define is a read-modify-write operation.

std::pair< bool, bool > MachineInstr::readsWritesVirtualRegister ( unsigned  Reg,

Return a pair of bools (reads, writes) indicating if this instruction reads or writes Reg.

readsWritesVirtualRegister - Return a pair of bools (reads, writes) indicating if this instruction reads or writes Reg.

This also considers partial defines. If Ops is not null, all operand indices for Reg are added.

This also considers partial defines.

bool llvm::MachineInstr::registerDefIsDead ( unsigned  Reg,

Returns true if the register is dead in this machine instruction.

If TargetRegisterInfo is passed, then it also checks if there is a dead def of a super-register.

MachineInstr * MachineInstr::removeFromBundle ( )

Unlink this instruction from its basic block and return it without deleting it.

If the instruction is part of a bundle, the other instructions in the bundle remain bundled.

MachineInstr * MachineInstr::removeFromParent ( )

Unlink 'this' from the containing basic block, and return it without deleting it.

This function can not be used on bundled instructions, use removeFromBundle() to remove individual instructions from a bundle.

void MachineInstr::tieOperands ( unsigned  DefIdx,
unsigned  UseIdx 
)

Add a tie between the register operands at DefIdx and UseIdx.

tieOperands - Mark operands at DefIdx and UseIdx as tied to each other.

The tie will cause the register allocator to ensure that the two operands are assigned the same physical register.

Tied operands are managed automatically for explicit operands in the MCInstrDesc. This method is for exceptional cases like inline asm.

Use and def operands can be tied together, indicated by a non-zero TiedTo field. TiedTo can have these values:

0: Operand is not tied to anything. 1 to TiedMax-1: Tied to getOperand(TiedTo-1). TiedMax: Tied to an operand >= TiedMax-1.

The tied def must be one of the first TiedMax operands on a normal instruction. INLINEASM instructions allow more tied defs.

bool llvm::MachineInstr::usesCustomInsertionHook ( QueryType  Type = IgnoreBundle) const

Return true if this instruction requires custom insertion support when the DAG scheduler is inserting it into a machine basic block.

If this is true for the instruction, it basically means that it is a pseudo instruction used at SelectionDAG time that is expanded out into magic code by the target when MachineInstrs are formed.

If this is true, the TargetLoweringInfo::InsertAtEndOfBasicBlock method is used to insert this into the MachineBasicBlock.
