CS has this patch in SG++:
http://gcc.gnu.org/ml/gcc-patches/2008-12/msg00199.html

This patch improves code size in a useful, target independent way, but 
was not committed upstream. It's not clear why. Since the patch does not 
belong to CodeSourcery, we can't upstream it ourselves either.

Is that patch a suitable candidate for Linaro GCC?

It is not upstreamable due to copyright issues, but we have a policy 
that we can keep such patches, if we wish.

The principle of not letting Linaro and SG++ diverge too far also 
suggests keeping it.

Any thoughts? If nobody objects soon I shall merge it in.

Andrew
