/* This module provides definitions used for creating and adding to
the symbol table. These routines are called from various symbol-
file-reading routines. This file holds the legacy API, which
relies on a global variable to work properly. New or maintained
symbol readers should use the builder API in buildsym.h.
The basic way this module is used is as follows:
scoped_free_pendings free_pending;
cust = start_symtab (...);
... read debug info ...
cust = end_symtab (...);
The compunit symtab pointer ("cust") is returned from both start_symtab
and end_symtab to simplify the debug info readers.
dbxread.c and xcoffread.c use another variation:
scoped_free_pendings free_pending;
cust = start_symtab (...);
... read debug info ...
cust = end_symtab (...);
... start_symtab + read + end_symtab repeated ...
