OperandRegisterTransformer

inner class OperandRegisterTransformer : L2Regenerator.AbstractOperandTransformer

An OperandRegisterTransformer is an L2OperandDispatcher suitable for copying operands for the enclosing L2Regenerator, when operand equivalency is via L2Register identity (i.e., when generatePhis is false).

Properties

var currentOperand: L2Operand?

The current operand being transformed. It gets set before a dispatch and read afterward, allowing the dispatch operation to replace it.

open override fun doOperand(operand: L2PcOperand)

Process an operand which is a constant level two offset into a L2Chunk's L2Instruction sequence.

open override fun doOperand(operand: L2PcVectorOperand)

Process an operand which is a vector of L2PcOperands.

open override fun doOperand(operand: L2PrimitiveOperand)

Process an operand which is a Primitive number.

open override fun doOperand(operand: L2ReadBoxedVectorOperand)

Process an operand which is a read of a vector of L2BoxedRegisters.

open override fun doOperand(operand: L2ReadFloatVectorOperand)

Process an operand which is a read of a vector of L2FloatRegisters.

open override fun doOperand(operand: L2ReadIntVectorOperand)

Process an operand which is a read of a vector of L2IntRegisters.

open override fun doOperand(operand: L2SelectorOperand)

Process an operand which is a literal A_Bundle which the resulting L2Chunk should be dependent upon for invalidation.

open override fun doOperand(operand: L2ReadBoxedOperand)

Process an operand which is a read of an AvailObject register.

open override fun doOperand(operand: L2ReadFloatOperand)

Process an operand which is a read of a double register.

open override fun doOperand(operand: L2ReadIntOperand)

Process an operand which is a read of an Int register.

open override fun doOperand(operand: L2WriteBoxedOperand)

Process an operand which is a write of an AvailObject register.

open fun mapBlock(block: L2BasicBlock): L2BasicBlock

Transform the given L2BasicBlock. Use the blockMap, adding an entry if necessary. Always produce the block representing the default code splitting path, the one with no conditions.

open fun mapSemanticValue(oldSemanticValue: L2SemanticValue): L2SemanticValue

Transform the given L2SemanticValue into another. By default this does nothing, but for a subclass that performs inlining, this can be useful for indicating that a semantic value is for the inlined frame rather than outer frame.
