Interface StackSlotAllocator

All Known Implementing Classes:

LSStackSlotAllocator, SimpleStackSlotAllocator

public interface StackSlotAllocator

A StackSlotAllocator is responsible for translating virtual stack slots into real stack slots. This includes changing all occurrences of VirtualStackSlot in the LIR to StackSlot.

Field Detail

allocatedSlots

static final DebugMetric allocatedSlots

The number of allocated stack slots.

reusedSlots

static final DebugMetric reusedSlots

The number of reused stack slots.

allocatedFramesize

static final DebugMetric allocatedFramesize

The size (in bytes) required for all allocated stack slots. Note that this number corresponds to the actual frame size and might include alignment.
