- which initializes to read a symbol file; os9k_new_init, which
- discards existing cached information when all symbols are being
- discarded; and os9k_symfile_read, which reads a symbol table
- from a file.
-
- os9k_symfile_read 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. os9k_psymtab_to_symtab() is the function that does this */
