Constructor Detail

ToAryInstr

public ToAryInstr(Variable result,
                  Operand array)

Method Detail

getArray

public Operand getArray()

canBeDeletedFromScope

public boolean canBeDeletedFromScope(FullInterpreterContext fic)

Overrides:

canBeDeletedFromScope in class Instr

simplifyAndGetResult

public Operand simplifyAndGetResult(IRScope scope,
                                    java.util.Map<Operand,Operand> valueMap)

Description copied from class: Instr

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

Overrides:

simplifyAndGetResult in class Instr

Parameters:

scope - where this instr exists

valueMap - Mapping from operands to their simplified values

Returns:

simplified result / output of this instruction

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.

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class ResultBaseInstr

decode

public static ToAryInstr decode(IRReaderDecoder d)

interpret

public java.lang.Object interpret(ThreadContext context,
                                  StaticScope currScope,
                                  DynamicScope currDynScope,
                                  IRubyObject self,
                                  java.lang.Object[] temp)

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
