I was using some ad-hoc command line tricks, including
objcopy -j .init.data build/multi_v7_defconfig/vmlinux /tmp/initdata
nm initdata | sort -n | { read start b sym ; while read a b c ; do objdump -Dr
--start-address=0x$start --stop-address=0x$a initdata > initdata.d/$sym ;
start=$a ; sym=$c ; done }
(some manual sorting to delete the files that have pre-initialized symbols)
sum=0 ; nm /tmp/initdata | sort -n | { read start b sym ; while read a b c ;
do test -e ../$sym && { echo $[0x$a - 0x$start]\ $sym ; sum=$[$sum +
$[0x$a - 0x$start]] ; } ; start=$a ; sym=$c ; done ; echo $sum;}
I'm sure there are better ways to do this, and the manual step I used at
first was faulty.
