Detailed Description

Base class for tracking ValueAsMetadata/DIArgLists with user lookups and Owner callbacks outside of ValueAsMetadata.

Currently only inherited by DPValue; if other classes need to use it, then a SubclassID will need to be added (either as a new field or by making DebugValue into a PointerIntUnion) to discriminate between the subclasses in lookup and callback handling.

◆ handleChangedValue()

void DebugValueUser::handleChangedValue ( void *  Old,

To be called by ReplaceableMetadataImpl::replaceAllUsesWith, where Old is a pointer to one of the pointers in DebugValues (so should be type Metadata**), and NewDebugValue is the new Metadata* that is replacing *Old.

For manually replacing elements of DebugValues, resetDebugValue(Idx, NewDebugValue) should be used instead.
