◆ getReferencedTypeDieEntry()

const DWARFDebugInfoEntry * llvm::dwarf_linker::parallel::DependencyTracker::LiveRootWorklistItemTy::getReferencedTypeDieEntry ( ) const

inline

Returns: the DIE actually referenced by ReferencedByDieEntry, whose placement (rather than the enclosing RootDieEntry's) determines whether ReferencedByDieEntry may remain in the type table. Null when the referenced DIE is RootDieEntry itself, in which case RootDieEntry's placement is used instead.

Member Data Documentation

◆ ReferencedByCU

CompileUnit* llvm::dwarf_linker::parallel::DependencyTracker::LiveRootWorklistItemTy::ReferencedByCU = nullptr

protected

Another root entry which references this RootDieEntry.

ReferencedByDieEntry is kept to update placement. if RootDieEntry has placement incompatible with placement of ReferencedByDieEntry then it should be updated.

Definition at line 213 of file DependencyTracker.h.

Referenced by getReferencedByEntry(), hasReferencedByOtherEntry(), and LiveRootWorklistItemTy().

◆ ReferencedByDieEntry

const DWARFDebugInfoEntry* llvm::dwarf_linker::parallel::DependencyTracker::LiveRootWorklistItemTy::ReferencedByDieEntry = nullptr

protected

Definition at line 214 of file DependencyTracker.h.

Referenced by getReferencedByEntry(), and LiveRootWorklistItemTy().

◆ ReferencedTypeDieEntry

const DWARFDebugInfoEntry* llvm::dwarf_linker::parallel::DependencyTracker::LiveRootWorklistItemTy::ReferencedTypeDieEntry = nullptr

protected

The DIE actually referenced by ReferencedByDieEntry.

It lives in the same CU as RootDieEntry, but its placement can differ: RootDieEntry is the enclosing root that is marked as kept, whereas this DIE may be a nested type demoted independently. That placement, not RootDieEntry's, determines whether ReferencedByDieEntry may remain in the type table. Null when RootDieEntry is the referenced DIE itself.
