AttrAssignInstr

public AttrAssignInstr(Operand obj,

                       Operand[] args)

AttrAssignInstr

public AttrAssignInstr(AttrAssignInstr instr)

Method Detail

cloneForInlining

public Instr cloneForInlining(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope). This requires renaming variables and labels to eliminate naming conflicts.

Overrides:

cloneForInlining in class NoResultCallInstr

Parameters:

ii - This object manages renaming of variables and labels, handles args and return values.

Returns:

a new instruction that can be used in the target scope.

specializeForInterpretation

public CallBase specializeForInterpretation()

Description copied from class: CallBase

Interpreter can ask the instruction if it knows how to make a more efficient instruction for direct interpretation.

Specified by:

specializeForInterpretation in interface Specializeable

Overrides:

specializeForInterpretation in class NoResultCallInstr

Returns:

itself or more efficient but semantically equivalent instr

interpret

public java.lang.Object interpret(ThreadContext context,
                                  DynamicScope dynamicScope,
                                  IRubyObject self,
                                  java.lang.Object[] temp,
                                  Block block)

Overrides:

interpret in class CallBase

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class NoResultCallInstr
