◆ computeDestructuringInfo()

static std::optional<MemorySlotDestructuringInfo> computeDestructuringInfo	(	DestructurableMemorySlot &	slot,
		const DataLayout &	dataLayout
	)

static

Computes information for slot destructuring.

This will compute whether this slot can be destructured and data to perform the destructuring. Returns nothing if the slot cannot be destructured or if there is no useful work to be done.

		DestructurableAllocationOpInterface	allocator,
		RewriterBase &	rewriter,
		const DataLayout &	dataLayout,
		MemorySlotDestructuringInfo &	info,

	)

static

Performs the destructuring of a destructible slot given associated destructuring information.

The provided slot will be destructured in subslots as specified by its allocator.
