	In order to determine which object files aren't used in building the
standalone boot applications, first build the standalone libraries

	$ cd $SRC/stand/lib ; make install

Next, collect some information from the linking process:

	$ cd $SRC/psm/stand/boot/`uname -p`/`uname -m`
	$ rm -f *.bin *boot *boot.elf
	$ LD_OPTIONS="-Dbindings,files,symbols" make all > /dev/null 2> ld.debug

The following sort of information ends up in ld.debug (note that the debugging
output from the link-editor is not considered a 'stable interface' and may
change in the future):

	debug:
	debug: file=/.../proto/root_sparc/stand/lib/libcrypto.a(cryptlib.o)  [ ET_REL ]
	debug:
	debug: symbol table processing; input file=/.../proto/root_sparc/stand/lib/libcrypto.a(cryptlib.o)  [ ET_REL ]
	debug: symbol[1]=cryptlib.c
	...

Now run the following script

	#!/bin/sh -

	for obj in	$SRC/stand/lib/crypto/objs/*.o	\
			$SRC/stand/lib/fs/*/objs/*.o	\
			$SRC/stand/lib/sa/objs/*.o	\
			$SRC/stand/lib/ssl/objs/*.o	\
			$SRC/stand/lib/wanboot/objs/*.o
	do
		f=`basename $obj`
		if egrep "^debug: file=.*\($f\)" ld.debug > /dev/null
		then
			:
		else
			echo $obj
		fi
	done

to determine which of the .o files appears in none of the loader debug output
(and therefore is unused).
