Methods

Modifier and Type	Method and Description
Instr	clone(CloneInfo 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).
void	decrementLVarScopeDepth()
LocalVariable	getLocalVar() This is the variable that is being stored into in this scope.
IRScope	getScope()
Operand	getValue()
Object	interpret(ThreadContext context, StaticScope currScope, DynamicScope currDynScope, IRubyObject self, Object[] temp)
void	simplifyOperands(Map<Operand,Operand> valueMap, boolean force) getLocalVar is saved for location and should not be simplified so we still know its original depth/offset.
String	toString()
void	visit(IRVisitor visitor)

Constructor Detail

StoreLocalVarInstr

public StoreLocalVarInstr(Operand value,
                  IRScope scope,
                  LocalVariable lvar)

Method Detail

getValue

public Operand getValue()

getLocalVar

public LocalVariable getLocalVar()

This is the variable that is being stored into in this scope. This variable doesn't participate in the computation itself. We just use it as a proxy for its (a) name (b) offset (c) scope-depth.

getScope

public IRScope getScope()

toString

public String toString()

Overrides:

toString in class Instr

decrementLVarScopeDepth

public void decrementLVarScopeDepth()

simplifyOperands

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

getLocalVar is saved for location and should not be simplified so we still know its original depth/offset.

Overrides:

simplifyOperands in class Instr

clone

public Instr clone(CloneInfo 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 might renaming variables and labels to eliminate naming conflicts. The implementation might vary on the cloning mode.

Specified by:

clone 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,
               StaticScope currScope,
               DynamicScope currDynScope,
               IRubyObject self,
               Object[] temp)

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
