physicalSuccessor	back to summary
public InstructionHandle physicalSuccessor() Returns an InstructionHandle to the physical successor of this JsrInstruction. For this method to work, this JsrInstruction object must not be shared between multiple InstructionHandle objects! Formally, there must not be InstructionHandle objects i, j where i != j and i.getInstruction() == this == j.getInstruction(). Returns:InstructionHandle an InstructionHandle to the "next" instruction that will be executed when RETurned from a subroutine.

physicalSuccessor

back to summary

public InstructionHandle physicalSuccessor()

Returns an InstructionHandle to the physical successor of this JsrInstruction. For this method to work, this JsrInstruction object must not be shared between multiple InstructionHandle objects! Formally, there must not be InstructionHandle objects i, j where i != j and i.getInstruction() == this == j.getInstruction().

Returns:InstructionHandle: an InstructionHandle to the "next" instruction that will be executed when RETurned from a subroutine.
