+	* objfiles.h (struct objfile): New fields: separate_debug_objfile
+	and separate_debug_objfile_backlink.
+	(put_objfile_before): New declaration.
+	* symfile.c (symbol_file_add_with_addrs_or_offsets): If this
+	objfile has its debug info in a separate file, read that,
+	too. Save the addrs argument, so we can use it again to read the

+	it.
+	(reread_symbols): After re-reading an objfile, call

+	objfile, if it has one.
+	(reread_separate_symbols, find_separate_debug_file,
+	get_debug_link_info, separate_debug_file_exists): New functions.
+	(debug_file_directory): New global var.
+	(_initialize_symfile): Initialize debug_file_directory, and
+	provide the new `set debug-file-directory' command to let the user
+	change it.
+	* objfiles.c (free_objfile): If this objfile has its debug info in
+	a separate objfile, free that one too.  If this is itself a

+On @sc{elf} based systems, @value{GDBN} supports automatically loading
+symbol tables and debug information from a file separate from the
+executable.  This works by putting information in the executable about
+the name and checksum of the file with debug information.  When
+@value{GDBN} reads such an executable it automatically tries to locate
+the debug file and load it. 
+
+@value{GDBN} searchs for the file first in the same directory as the
+executable, and then in a subdirectory called @file{.debug}. 
+If both these fail @value{GDBN} looks in the global debug directory, with the
+full pathname of the executable.  So if you are loading
+@file{/usr/bin/ls} and it references the debug file @file{ls.debug}
+@value{GDBN} will look for @file{usr/bin/ls.debug} in the global debug
+directory.
