Manage lifetime of a slot tracker for printing IR.

Wrapper around the SlotTracker used internally by AsmWriter. This class allows callers to share the cost of incorporating the metadata in a module or a function.

If the IR changes from underneath ModuleSlotTracker, strings like "" will be printed, or, worse, the wrong slots entirely.

ModuleSlotTracker::ModuleSlotTracker ( const Module * M, bool ShouldInitializeAllMetadata = true ) explicit

Construct a slot tracker from a module.

If M is nullptr, uses a null slot tracker. Otherwise, initializes a slot tracker, and initializes all metadata slots. ShouldInitializeAllMetadata defaults to true because this is expected to be shared between multiple callers, and otherwise MDNode references will not match up.

◆ incorporateFunction()

void ModuleSlotTracker::incorporateFunction ( const Function & F )

Incorporate the given function.

Purge the currently incorporated function and incorporate F. If F is currently incorporated, this is a no-op.
