Constructor & Destructor Documentation

◆ SlotTracker() [1/4]

SlotTracker::SlotTracker	(	const Module *	M,
		bool	ShouldInitializeAllMetadata = false )

explicit

Construct from a module.

◆ SlotTracker() [2/4]

SlotTracker::SlotTracker	(	const Function *	F,
		bool	ShouldInitializeAllMetadata = false )

explicit

Construct from a function, starting out in incorp state.

If ShouldInitializeAllMetadata, initializes all metadata in all functions, giving correct numbering for metadata referenced only from within a function (even if no functions have been initialized).

Clean up after incorporating a function.

This will reset the state of the machine back to just the module contents.

This is the only way to get out of the function incorporation state that affects get*Slot/Create*Slot. Function incorporation state is indicated by TheFunction != 0.
