class MetadataTracking

Detailed Description

Shared implementation of use-lists for replaceable metadata.

Most metadata cannot be RAUW'ed. This is a shared implementation of use-lists and associated API for the three that support it ( ValueAsMetadata, TempMDNode, and DIArgList).

◆ resolveAllUses()

void ReplaceableMetadataImpl::resolveAllUses ( bool  ResolveUsers = true)

Resolve all uses of this.
