- To handle extremely large binaries, we want to use a more efficient data
- structure than a singly-linked list to represent aranges. So instead we
- use an arange-set, which supports efficient insertions and queries. We
- use a simple arange-set with no values attached to represent the aranges
- in a compilation unit and we also use a global arange-set to store all
- the aranges in all the compilation units. The global arange-set stores
- values which are pointers to the compilation units.
-
- Normally aranges in the global set do not overlap, but this can happen.
- To simplify things and to prevent excessive memory usage, an arange in
- the global set can only point to at most one compilation unit. In case
- of an overlap, the pointer is set to NULL, meaning that there are more
- than one compilation units containing that arange. Code that looks up
- the global set should fall back to searching all compilation units if
