fun L2ReadIntVectorOperand(elements: List<L2ReadIntOperand>)

Construct a new L2ReadIntVectorOperand with the specified List of L2ReadIntOperands.

Functions

open fun addDestinationRegistersTo(destinationRegisters: MutableList<L2Register>)

Move any registers used as destinations within me into the provided list.

Link copied to clipboard
open override fun addReadsTo(readOperands: MutableList<L2ReadOperand<*>>)

Capture all L2ReadOperands within this operand into the provided List.

Link copied to clipboard
open override fun addSourceRegistersTo(sourceRegisters: MutableList<L2Register>)

Move any registers used as sources within me into the provided list.

Link copied to clipboard
open fun addWritesTo(writeOperands: MutableList<L2WriteOperand<*>>)

Capture all L2WriteOperands within this operand into the provided List.

open fun adjustCloneForInstruction(theInstruction: L2Instruction)

This is a freshly cloned operand. Adjust it for use in the given L2Instruction. Note that the new instruction has not yet been installed into an L2BasicBlock.

Link copied to clipboard
open override fun appendTo(builder: StringBuilder)

Write a description of this operand to the given StringBuilder.

Link copied to clipboard
fun appendWithWarningsTo(    builder: StringBuilder,     indent: Int,     warningStyleChange: (Boolean) -> Unit)

Append a textual representation of this operand to the provided StringBuilder. If a style change is appropriate while building the string, invoke the warningStyleChange lambda with true to enable the warning style, and false to turn it off again.

open override fun assertHasBeenEmitted()

Assert that this operand knows its instruction, which should always be the case if the instruction has already been emitted.

open override fun clone(): L2ReadIntVectorOperand

open override fun clone(replacementElements: List<L2ReadIntOperand>): L2ReadIntVectorOperand

Create a vector like this one, but using the provided elements.

Link copied to clipboard
open override fun dispatchOperand(dispatcher: L2OperandDispatcher)

Dispatch this L2Operand to the provided L2OperandDispatcher.

Link copied to clipboard
fun elements(): List<L2ReadIntOperand>

Answer my List of L2ReadOperands.

Link copied to clipboard
open override fun instructionWasAdded(manifest: L2ValueManifest)

This is an operand of the given instruction, which was just added to its basic block. Its instruction was just set.

Link copied to clipboard
fun instructionWasAddedForPhi(predecessorEdges: List<L2PcOperand>)

This vector operand is the input to an L2_PHI_PSEUDO_OPERATION instruction that has just been added. Update it specially, to take into account the correspondence between vector elements and predecessor edges.

Link copied to clipboard
open override fun instructionWasInserted(newInstruction: L2Instruction)

This is an operand of the given instruction, which was just inserted into its basic block as part of an optimization pass.

Link copied to clipboard
open override fun instructionWasRemoved()

This is an operand of the given instruction, which was just removed from its basic block.

Link copied to clipboard
open override fun postOptimizationCleanup()

Now that chunk optimization has completed, remove information from this instruction that will no longer be needed in the finished chunk. Note that during subsequent inlining of this chunk at a call site, the type and synonym information will be reconstructed without too much cost.

Link copied to clipboard
fun registers(): List<L2IntRegister>

Answer a List of my elements' L2Registers.

open override fun replaceRegisters(registerRemap: Map<L2Register, L2Register>, theInstruction: L2Instruction)

Replace occurrences in this operand of each register that is a key of this map with the register that is the corresponding value. Do nothing to registers that are not keys of the map. Update all secondary structures, such as the instruction's source/destination collections.

Link copied to clipboard
open override fun setInstruction(theInstruction: L2Instruction?)

Set the instructionOrNull field.

open override fun toString(): String
Link copied to clipboard
open override fun transformEachRead(transformer: (L2ReadOperand<*>) -> L2ReadOperand<*>): L2ReadVectorOperand<L2IntRegister, L2ReadIntOperand>

Transform each L2ReadOperand through the given lambda, producing either a new L2Operand of the same type, or the receiver.
