allocate

fun allocate( code: A_RawFunction?, numObjects: Int, numIntegers: Int, numFloats: Int, offsetAfterInitialTryPrimitive: Int, theInstructions: List<L2Instruction>, controlFlowGraph: L2ControlFlowGraph, contingentValues: A_Set): L2Chunk

Allocate and set up a new L2Chunk with the given information. If code is non-null, set it up to use the new chunk for subsequent invocations.

Return

The new level two chunk.

Parameters

code

The code for which to use the new level two chunk, or null for the initial unoptimized chunk.

numObjects

The number of object registers that this chunk will require.

numIntegers

The number of integer registers that this chunk will require.

numFloats

The number of floating point registers that this chunk will require.

offsetAfterInitialTryPrimitive

The offset into my instructions at which to begin if this chunk's code was primitive and that primitive has already been attempted and failed.

theInstructions

A List of L2Instructions that can be executed in place of the level one nybblecodes.

controlFlowGraph

The optimized, non-SSA L2ControlFlowGraph. Useful for debugging. Eventually we'll want to capture a copy of the graph prior to conversion from SSA to support inlining.

contingentValues

A Set of methods on which the level two chunk depends.
