public AttrAssignInstr(Operand obj,

                       Operand value)
Method Detail

getOperands

public Operand[] getOperands()
Specified by:
getOperands in class Instr

simplifyOperands

public void simplifyOperands(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 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

Specified by:
simplifyOperands in class Instr

cloneForInlining

public Instr cloneForInlining(InlinerInfo ii)
Description copied from class: Instr
Clone the instruction for inlining -- this will rename all variables (including local variables and self!) and replace RECV_ARG and RETURN instructions to regular copy instructions,

Specified by:
cloneForInlining in class Instr

interpret

public Label interpret(InterpreterContext interp,
                       IRubyObject self)
Overrides:
interpret in class Instr
