public class GetConstInstr
extends GetInstr

A constant which we is not lexically scoped. This instruction will ask the source operand to get it directly.

Constructor Detail

GetConstInstr

public GetConstInstr(Variable dest,
                     Operand scopeOrObj,
                     java.lang.String constName)
Method Detail

simplifyAndGetResult

public Operand simplifyAndGetResult(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:
valueMap - Mapping from operands to their simplified values

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
