Constructor & Destructor Documentation

◆ SlotTracker() [1/4]

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

explicit

Construct from a module.

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).

Definition at line 945 of file AsmWriter.cpp.

◆ 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).

Definition at line 950 of file AsmWriter.cpp.

◆ SlotTracker() [3/4]

SlotTracker::SlotTracker ( const ModuleSummaryIndex * Index )

explicit

Construct from a module summary index.

Definition at line 954 of file AsmWriter.cpp.

◆ SlotTracker() [4/4]

llvm::SlotTracker::SlotTracker ( const SlotTracker & )

delete

◆ purgeFunction()

void SlotTracker::purgeFunction ( )

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.
