LLOIFF is an intermediate file format which exists only in memory. This format is generated by stage 1 of LLO. The design of this intermediate file format must be robust enough that it can handle file formats of all types
lifted to it. For example, PE-COFF (COFF meaning: including OBJ files), ELF, etc.
There can be multiple LLOIFF's at a given time, just as there can be multiple OBJ files in a LIB.
LLOIFF needs to provide a clean C++2017 interfacable class that contains all information possible about a given file. This information includes: symbols, sections, original file, size, virtual size, etc...
