Operand	simplifyAndGetResult(IRScope scope, Map<Operand,Operand> valueMap) This method takes as input a map of operands to their values, and outputs the result of this instruction.

simplifyOperands

public void simplifyOperands(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

simplifyAndGetResult

public Operand simplifyAndGetResult(IRScope scope,
                           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

valueMap - Mapping from operands to their simplified values
