- * src/MachOReaderRelocatable.hpp: To handle duplicate labels properly, rework how atoms sizes are set
- by iterating through sorted fAtoms rather than fAddrToAtom, . Change default alignment of commons
- to be the natural alignment of the size rounded up to the closest power of two and max it at 12.
- Build atoms in reverse symbol table order so that global atoms are constructed before locals.
- This assures that if there is a global and local label at the same location, the global label
- will become the atom's name and the local will be an alias. Properly handle a label
- at the end of a section. Handle R_ABS in relocations. Handle sect-diff relocs with addends.
