Method Summary

Modifier and Type	Method and Description
Instr	cloneForInlining(InlinerInfo ii) 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).
MethodHandle	getMethodHandle()
Operand[]	getOperands()
Variable	getResult()
java.lang.Object	interpret(ThreadContext context, DynamicScope currDynScope, IRubyObject self, java.lang.Object[] temp, Block block)
void	simplifyOperands(java.util.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.
java.lang.String	toString()
void	updateResult(Variable v)
void	visit(IRVisitor visitor)

simplifyOperands

public void simplifyOperands(java.util.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

toString

public java.lang.String toString()

Overrides:

toString in class Instr

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

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:
