                   Operand v)

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class OneOperandInstr

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:
