    Returns the location – Stack, Register or NoExpression – where the value computed by this instruction is stored. In this case an instruction is only considered to be an expression if it puts a value on the stack or in a register that is the result of some kind of computation; i.e., just copying, duplicating or moving a value between the stack and the registers is not considered to be an expression.

    Note

    This is primarily a convenience method that delegates to the method indexOfNextInstrution(PC,Boolean). However, given that this is also the standard method called by clients, it is often meaningful to directly implement this. In particular since most instructions cannot be modified by wide.

  47. final def isIsomorphic(thisPC: PC, otherPC: PC)(implicit code: Code): Boolean

    Determines if this instruction is isomorphic to the given instruction.

    Determines if this instruction is isomorphic to the given instruction.

    Two instructions are isomporphic if they access the same operand and register values and if the instructions have the same bytecode representation, except of (A) (potential) padding bytes and (B) the branch offset of JSR(_W) instructions. In the first case the branch offsets are corrected by the number of padding bytes and in the second case the absolute addresses are compared (i.e., whether both instructions call the same subroutine).

    For example, an aload_0 instruction is only isomorphic to another aload_0 instruction and is not isomorphic to an aload(0) instruction – though the runtime effect is the same. However, a LOOKUPSWITCH (TABLESWITCH) instruction is considered isomorphic to another respective instruction if the only difference is the number of padding bytes. Furthermore, two JSR(_W) instructions are isomorphic if and only if they jump to the same subroutine.

    Definition Classes
    ImplicitLocalVariableIndexInstructionLike
    Note

    The number of padding bytes is generally calculated by (otherPC % 4) - (thisPC %4) (=== "padding other" - "padding this") and should be added to the branch offsets of this (XYZ)switch instruction when the branch targets are compared to the other instructions branchoffsets.

    // "padding b" - "padding a"
    // === (3 - (bPC % 4)) - (3 - (aPC % 4))
    // === (aPC % 4) - (bPC %4)
    ,

    this.isIsomorphic(thisPC,thisPC) is always true

    The exceptions that may be thrown by the JVM at runtime if the execution of this instruction fails.

    The exceptions that may be thrown by the JVM at runtime if the execution of this instruction fails. I.e., these are neither exceptions that are explicitly created and then thrown by user code nor errors that may arise due to an invalid code base (in particular LinkageErrors). However, OutOfMemoryErrors are possible.

    The returned types always precisely describe the thrown exception; they are not upper bounds. All instructions – except of the InvocationInstructions and the ATHROW$ instruction – will always either succeed, throw a linkage time related exception or throw one of the specified exceptions.

    Returns the pcs of the instructions that may be executed next at runtime.

    Returns the pcs of the instructions that may be executed next at runtime. This method takes potentially thrown exceptions into account. I.e., every instruction that may throw an exception checks if it is handled locally and – if so – checks if an appropriate handler exists and – if so – also returns the first instruction of the handler. The chain may contain duplicates, iff the state is potentially different when the target instruction is reached.

    regularSuccessorsOnly

    If true, only those instructions are returned which are not related to an exception thrown by this instruction.

    returns

    The absolute addresses of all instructions that may be executed next at runtime.

  67. final def numberOfPoppedOperands(ctg: (Int) => ComputationalTypeCategory): Int

    The number of values that are popped from the operand stack.

    The number of values that are popped from the operand stack. Here, long and double values are also counted as one value though they use two stack slots. E.g., IADD (integer add) and LADD (long add) both pop two values and push one value.

    ctg

    A function that returns the computational type category of the value on the operand stack with a given value index. E.g., The top value on the operand stack has index '0' and may occupy one (for category 1 values) or two stack slots (for category 2 values.)

    Definition Classes
    LoadLocalVariableInstructionInstructionLike
    Note

    In case of some of the StackManagementInstruction the number of popped values is not fixed. In that case the number depends on the concrete layout of the operand stack. E.g., the POP2 instruction may just pop one categeory 2 value (of type long or double) or two category 1 values.

    Note

    In case of some of the StackManagementInstruction this number is not fixed. In that case the number depends on the concrete layout of the operand stack.
