28	In order to determine which object files aren't used in building the
29standalone boot applications, first build the standalone libraries
30
31	$ cd $SRC/stand/lib ; make install
32
33Next, collect some information from the linking process:
34
35	$ cd $SRC/psm/stand/boot/`uname -p`/`uname -m`
36	$ rm -f *.bin *boot *boot.elf
37	$ LD_OPTIONS="-Dbindings,files,symbols" make all > /dev/null 2> ld.debug
38
39The following sort of information ends up in ld.debug (note that the debugging
40output from the link-editor is not considered a 'stable interface' and may
41change in the future):
42
43	debug:
44	debug: file=/.../proto/root_sparc/stand/lib/libcrypto.a(cryptlib.o)  [ ET_REL ]
45	debug:
46	debug: symbol table processing; input file=/.../proto/root_sparc/stand/lib/libcrypto.a(cryptlib.o)  [ ET_REL ]
47	debug: symbol[1]=cryptlib.c
48	...
49
50Now run the following script
51
52	#!/bin/sh -
53
54	for obj in	$SRC/stand/lib/crypto/objs/*.o	\
55			$SRC/stand/lib/fs/*/objs/*.o	\
56			$SRC/stand/lib/sa/objs/*.o	\
57			$SRC/stand/lib/ssl/objs/*.o	\
58			$SRC/stand/lib/wanboot/objs/*.o
59	do
60		f=`basename $obj`
61		if egrep "^debug: file=.*\($f\)" ld.debug > /dev/null
62		then
63			:
64		else
65			echo $obj
66		fi
67	done
68
69to determine which of the .o files appears in none of the loader debug output
70(and therefore is unused).
