-/* This module provides subroutines used for creating and adding to
- the symbol table. These routines are called from various symbol-
- file-reading routines.
-
- Routines to support specific debugging information formats (stabs,
- DWARF, etc) belong somewhere else.
-
- 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.
-
- There are minor variations on this, e.g., dwarf2read.c splits end_symtab
- into two calls: end_symtab_get_static_block, end_symtab_from_static_block,
- but all debug info readers follow this basic flow.
-
- Reading DWARF Type Units is another variation:
-
- scoped_free_pendings free_pending;
- cust = start_symtab (...);
- ... read debug info ...
- cust = end_expandable_symtab (...);
-
- And then reading subsequent Type Units within the containing "Comp Unit"
- will use a second flow:
-
- scoped_free_pendings free_pending;
- cust = restart_symtab (...);
- ... read debug info ...
- cust = augment_type_symtab (...);
-
- 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 ...
