L1InstructionDecoder

A mechanism for extracting consecutive operations and operands from an A_RawFunction.

Constructors

Answer whether the receiver has reached the end of its instructions.

Get one nybble from the stream of nybblecodes.

Consume the next nybblecode operand.

Consume the next nybblecode operation, but not operands.

Consume the next nybblecode operation, but not operands.

fun pc(): Int

Answer the current one-based program counter.

fun pc(pc: Int)

Set the pc. This can be done independently of the call to AvailObject.setUpInstructionDecoder.

open override fun toString(): String

The actual longSlots field from the current A_RawFunction being traced.

The long index just after consuming the last nybble.

The shift just after consuming the last nybble.

The current shift factor for extracting nybblecodes from the long at the current longIndex.
