Detailed Description

DwarfStringPoolEntryRef: Dwarf string pool entry reference.

Dwarf string pool entry keeps string value and its data. There are two variants how data are represented:

1. By value - StringMapEntry<DwarfStringPoolEntry>.
2. By pointer - StringMapEntry<DwarfStringPoolEntry *>.

The "By pointer" variant allows for reducing memory usage for the case when string pool entry does not have data: it keeps the null pointer and so no need to waste space for the full DwarfStringPoolEntry. It is recommended to use "By pointer" variant if not all entries of dwarf string pool have corresponding DwarfStringPoolEntry.
