Hi, great!

There is a couple of tasks related to the generated assembler that can
be improved. The long-waiting large size task is improving the current
register allocator. A bit less demanding one is investigating whether
reordering instructions makes sense on modern machines (also not very
small though).

If you want to know more, we usually hang out on IRC #pypy on
freenode, otherwise feel free to ask more questions here.
