    This adds a simple perl script for reading two files as produced by
    the stackusage script and computing the changes in stack usage. For
    example:

    $ scripts/stackusage -o /tmp/old.su CC=gcc-4.7 -j8 fs/ext4/
    $ scripts/stackusage -o /tmp/new.su CC=gcc-5.0 -j8 fs/ext4/
    $ scripts/stackdelta /tmp/{old,new}.su | sort -k5,5g

    shows that gcc 5.0 generally produces less stack-hungry code than gcc
    4.7. Obviously, the script can also be used for measuring the effect
    of commits, .config tweaks or whatnot.
