Detailed Description

MachineInstr - 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

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.

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.

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).

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

canFoldAsLoad - 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.

isConvertibleTo3Addr - 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).

Return true if this instruction behaves the same way as the generic REG_SEQUENCE instructions. E.g., on ARM, dX VMOVDRR rY, rZ is equivalent to dX = REG_SEQUENCE rY, ssub_0, rZ, ssub_1.

Note that for the optimizers to be able to take advantage of this property, TargetInstrInfo::getRegSequenceLikeInputs has to be override accordingly.

void MachineInstr::tieOperands ( unsigned  DefIdx,

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

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

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.
