getOperands in class Instr

getResult

Specified by:

getResult in interface ResultInstr

updateResult

public void updateResult(Variable v)

Specified by:

updateResult in interface ResultInstr

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.

newClass

private RubyModule newClass(ThreadContext context,
                            IRubyObject self,
                            RubyModule classContainer,
                            DynamicScope currDynScope,
                            java.lang.Object[] temp)

interpret

                                  DynamicScope currDynScope,

                                  java.lang.Object[] temp,
                                  Block block)
