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
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 \
do
f=`basename $obj`
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).
