emptyStackMap :: StackMap Source #
An empty stack map, with all slots available.
getStackSlotFor :: StackMap -> Unique -> (StackMap, Int) Source #
If this vreg unique already has a stack assignment then return the slot number, otherwise allocate a new slot, and update the map.
getStackUse :: StackMap -> Int Source #
Return the number of stack slots that were allocated
