- * Modularized symtab info into a new db_symtab_t type.
- * Modified db_add_symbol_table and others accordingly.
- * Defined db_sym_t, a new (opaque) type used to represent
- * symbols. This should support all sort of future symtable
- * formats. Functions like db_qualify take a db_sym_t now.
- * New db_symbol_values() function to explode the content
- * of a db_sym_t.
- * db_search_symbol() replaces db_find_sym_and_offset(), which is
- * now a macro defined in our (new) header file. This new
- * function accepts more restrictive searches, which are
- * entirely delegated to the symtab-specific code.
- * Accordingly, db_printsym() accepts a strategy parameter.
- * New db_line_at_pc() function.
- * Renamed misleading db_eqsym into db_eqname.
