Functions

createContinuationExceptFrame

@JvmStatic

fun createContinuationExceptFrame(function: A_Function, caller: A_Continuation, registerDump: AvailObject, pc: Int, stackp: Int, levelTwoChunk: L2Chunk, levelTwoOffset: Int): AvailObject

Create a mutable continuation with the specified fields. Fill the stack frame slots with nil.

createContinuationWithFrame

fun createContinuationWithFrame(function: A_Function, caller: A_Continuation, registerDump: AvailObject, pc: Int, stackp: Int, levelTwoChunk: L2Chunk, levelTwoOffset: Int, frameValues: List<A_BasicObject>, zeroBasedStartIndex: Int): AvailObject

Create a mutable continuation with the specified fields. Initialize the stack slot from the list of fields.

createDummyContinuation

@JvmStatic

fun createDummyContinuation(function: A_Function, boxedRegisters: Array<AvailObject>, unboxedRegisters: LongArray, levelTwoChunk: L2Chunk, levelTwoOffset: Int): AvailObject

Create a private continuation with the specified fields. The continuation will never be visible to level one code, but is used to carry register state (and L2Chunk& offset) during stack unwinding for a reification. It will be executed (in the reverse of stack order) to run L2 code that reconstitutes a real continuation, which is pushed on the Interpreter.getReifiedContinuation stack.

createLabelContinuation

fun createLabelContinuation(function: A_Function, caller: A_Continuation, startingChunk: L2Chunk, startingOffset: Int, args: List<AvailObject>): A_Continuation

Create a new continuation with the given data. The continuation should represent the state upon entering the new context - i.e., set the pc to the first instruction, clear the stack, and set up new local variables.

dumpStackThen

fun dumpStackThen(runtime: AvailRuntime, textInterface: TextInterface, availContinuation: A_Continuation, action: (List<String>) -> Unit)

Create a list of descriptions of the stack frames (A_Continuations) of the specified continuation. Invoke the specified Kotlin function with the resultant list. This list begins with the newest frame and ends with the base frame.

functionStatic

@JvmStatic

fun functionStatic(self: AvailObject): A_Function

nilSubstitute

fun nilSubstitute(): AvailObject

Answer a substitute for nil for a non-existent caller. This is primarily for use by P_ContinuationStackData.
