- or not (may be shared library for example), add all the global
- function and data symbols to the minimal symbol table.

-/* Scan and build partial symbols for a symbol file.
- We have been initialized by a call to nlm_symfile_init, which

-
- SECTION_OFFSETS is a set of offsets to apply to relocate the symbols
- in each section. We simplify it down to a single offset for all
- symbols. FIXME.
-
- MAINLINE is true if we are reading the main symbol
- table (as opposed to a shared lib or dynamically loaded file).
-
- This function only does the minimum work necessary for letting the
- user "name" things symbolically; it does not read the entire symtab.
- Instead, it reads the external and static symbols and puts them in partial
- symbol tables. When more extensive information is requested of a
- file, the corresponding partial symbol table is mutated into a full
- fledged symbol table by going back and reading the symbols
- for real.
-
- Note that NLM files have two sets of information that is potentially
- useful for building gdb's minimal symbol table. The first is a list
- of the publically exported symbols, and is currently used to build
- bfd's canonical symbol table. The second is an optional native debugging
- format which contains additional symbols (and possibly duplicates of
- the publically exported symbols). The optional native debugging format
- is not currently used. */
