public PopJumpIfTrueOpcode(PythonBytecodeInstruction instruction,
 int jumpTarget)

Method Details

getPossibleNextBytecodeIndexList

public List<Integer> getPossibleNextBytecodeIndexList()

Description copied from interface: Opcode

Return the possible next bytecode index after this instruction is executed. The default simply return [getBytecodeIndex() + 1], but is typically overwritten in jump instructions.

Returns:

the possible next bytecode index after this instruction is executed

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().

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().

implement

public void implement(FunctionMetadata functionMetadata,
 StackMetadata stackMetadata)

Description copied from interface: Opcode

Implements the opcode.

Parameters:

functionMetadata - Metadata about the function being compiled.

stackMetadata - Metadata about the state of the stack when this instruction is executed.
