2N/A In order to determine which object files aren't used in building the

2N/Astandalone boot applications, first build the standalone libraries

2N/A

2N/A $ cd $SRC/stand/lib ; make install

2N/A

2N/ANext, collect some information from the linking process:

2N/A

2N/A $ cd $SRC/psm/stand/boot/`uname -p`/`uname -m`

2N/A $ rm -f *.bin *boot *boot.elf

2N/A $ LD_OPTIONS="-Dbindings,files,symbols" make all > /dev/null 2> ld.debug

2N/A

2N/AThe following sort of information ends up in ld.debug (note that the debugging

2N/Aoutput from the link-editor is not considered a 'stable interface' and may

2N/Achange in the future):

2N/A

2N/A debug:

2N/A debug: file=/.../proto/root_sparc/stand/lib/libcrypto.a(cryptlib.o) [ ET_REL ]

2N/A debug:

2N/A debug: symbol table processing; input file=/.../proto/root_sparc/stand/lib/libcrypto.a(cryptlib.o) [ ET_REL ]

2N/A debug: symbol[1]=cryptlib.c

2N/A ...

2N/A

2N/ANow run the following script

2N/A

2N/A #!/bin/sh -

2N/A

2N/A for obj in $SRC/stand/lib/crypto/objs/*.o \

2N/A $SRC/stand/lib/fs/*/objs/*.o \

2N/A $SRC/stand/lib/sa/objs/*.o \

2N/A $SRC/stand/lib/ssl/objs/*.o \

2N/A $SRC/stand/lib/wanboot/objs/*.o

2N/A do

2N/A f=`basename $obj`

2N/A if egrep "^debug: file=.*\($f\)" ld.debug > /dev/null

2N/A then

2N/A :

2N/A else

2N/A echo $obj

2N/A fi

2N/A done

2N/A

2N/Ato determine which of the .o files appears in none of the loader debug output

2N/A(and therefore is unused).
