22 which initializes to read a symbol file; os9k_new_init, which
23 discards existing cached information when all symbols are being
24 discarded; and os9k_symfile_read, which reads a symbol table
27 os9k_symfile_read only does the minimum work necessary for letting the
28 user "name" things symbolically; it does not read the entire symtab.
29 Instead, it reads the external and static symbols and puts them in partial
30 symbol tables. When more extensive information is requested of a
31 file, the corresponding partial symbol table is mutated into a full
32 fledged symbol table by going back and reading the symbols
33 for real. os9k_psymtab_to_symtab() is the function that does this */

1030 to here via the misc_info field. Therefore, we can fill in
1031 a reliable texthigh by taking the address plus size of the
1032 last function in the file.

1035 in the file is static. See the paragraph below for more comments
