I consider that an experimental commit. It's meant to solve the problems we're having on a few very large compilation units with the limited length of branches. But if the cure turns out to be worse than the illness I'm ready to pull it again. A more proper patchset should modify the linker scripts to avoid the excessive large number of sections you've noticed. Somebody else is currently working on a patchset to allow the --gc-sections ld option so I decieded to take the path of least resistance for now. Ralf
