... and forgot to mention. Main reason why packing seemed worthwhile to
me are cases where early inlining inline many copies of same function
and introduces a lot of packing oppurtunities. This tends to happen for
C++ programs when inlined function has static temporary. But I guess we
can see how the simpler implementation works and solve problems only if
they appear.
