public AbstractOpcode(PythonBytecodeInstruction instruction)

Method Details

getInstruction

public PythonBytecodeInstruction getInstruction()

getBytecodeIndex

public int getBytecodeIndex()

Description copied from interface: Opcode

Return the bytecode index of the instruction, which can be used to identify the instruction as the target of a jump.

Specified by:

getBytecodeIndex in interface Opcode

Returns:

The bytecode index of the instruction, which is defined as the number of instructions before it in the instruction listing.

isJumpTarget

public boolean isJumpTarget()

Specified by:

isJumpTarget in interface Opcode

Returns:

true if this opcode the target of a jump

getStackMetadataAfterInstructionForBranches

public List<StackMetadata> getStackMetadataAfterInstructionForBranches(FunctionMetadata functionMetadata,
 StackMetadata stackMetadata)

Description copied from interface: Opcode

Return a list of StackMetadata corresponding to each branch returned by Opcode.getPossibleNextBytecodeIndexList().

Specified by:

getStackMetadataAfterInstructionForBranches in interface Opcode

Parameters:

functionMetadata - Metadata about the function being compiled.

stackMetadata - the StackMetadata just before this instruction is executed.

Returns:

a new List, the same size as Opcode.getPossibleNextBytecodeIndexList(), containing the StackMetadata after this instruction is executed for the given branch in Opcode.getPossibleNextBytecodeIndexList().

getStackMetadataAfterInstruction

protected abstract StackMetadata getStackMetadataAfterInstruction(FunctionMetadata functionMetadata,
 StackMetadata stackMetadata)

lookupInstruction

public static OpcodeDescriptor lookupInstruction(String name)

toString

public String toString()

Overrides:

toString in class Object
