Method Detail

getOperands

public Operand[] getOperands()

Specified by:

getOperands in class Instr

toString

public String toString()

Overrides:

toString in class Instr

getResult

public Variable getResult()

Specified by:

getResult in interface ResultInstr

updateResult

public void updateResult(Variable v)

Specified by:

updateResult in interface ResultInstr

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 Instr

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.

interpret

public Object interpret(ThreadContext context,
               DynamicScope currDynScope,
               IRubyObject self,
               Object[] temp,
               Block block)

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
