class MachineModuleSlotTracker

Declaration

class MachineModuleSlotTracker : public ModuleSlotTracker { /* full declaration omitted */ };

Description

Manage lifetime of a slot tracker for printing IR. Wrapper around the \a SlotTracker used internally by \a 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 \a ModuleSlotTracker, strings like "<badref>" will be printed, or, worse, the wrong slots entirely.
