Methods

Modifier and Type	Method and Description
Instr	cloneForInlining(InlinerInfo inlinerInfo) 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).
StringLiteral	getName()
Object	interpret(ThreadContext context, DynamicScope currDynScope, IRubyObject self, Object[] temp, Block block)
void	simplifyOperands(Map<Operand,Operand> valueMap, boolean force) This method takes as input a map of operands to their values, and outputs If the value map provides a value for any of the instruction's operands this method is expected to replace the original operands with the simplified values.

Method Detail

simplifyOperands

public void simplifyOperands(Map<Operand,Operand> valueMap,
                    boolean force)

Description copied from class: Instr

This method takes as input a map of operands to their values, and outputs If the value map provides a value for any of the instruction's operands this method is expected to replace the original operands with the simplified values. It is not required that it do so -- code correctness is not compromised by failure to simplify

Overrides:

simplifyOperands in class Instr

getName

public StringLiteral getName()

cloneForInlining

public Instr cloneForInlining(InlinerInfo inlinerInfo)

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:

inlinerInfo - 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.

toString

public String toString()

Overrides:

toString in class Instr

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
