Method Detail

run

protected void run(TargetDescription target,
                   LIRGenerationResult lirGenRes,
                   AllocationPhase.AllocationContext context)

colorLirOperand

protected Value colorLirOperand(LIRInstruction op,
                                Variable operand,
                                LIRInstruction.OperandMode mode)

Assigns the allocated location for an LIR instruction operand back into the instruction.

Parameters:

op - current LIRInstruction

operand - an LIR instruction operand

mode - the usage mode for operand by the instruction

Returns:

the location assigned for the operand

assignLocations

protected LIRInstruction assignLocations(LIRInstruction inputOp)

Assigns the operand of an LIRInstruction.

Parameters:

inputOp - The LIRInstruction that should be colored.

Returns:

the LIRInstruction that should be emitted. A null return deletes the instruction.
