We would very much like to continue this work, because even in this
simple code motion algorithm we have extra gain beside the mentioned
algorithm when optimizing for size. I expect significant reductions
the more sophisticated factorings. Do you support this?
I have taken no position on this work. I simply pointed out that it
appeared to be a generalization of cross-jumping, which is something
didn't mention, so I wasn't sure if you were aware of it.
