Thanks for your interest.

There are a number of general projects for gcc.  Google's Summer of
Code is not running right now, but the wiki page for it points to a
number of lists of open projects:

http://gcc.gnu.org/wiki/SummerOfCode

Most of those are not specifically related to cross-compiling, but of
course improvements to the general compiler will improve all targets.

The ARM target is in pretty good shape in general.  However, I do know
that the code size is not as good as that generated by ARM's
proprietary compiler.  So that would an area to investigate.

Also a quick bugzilla search for ARM turns up a number of open bug
reports.  I haven't looked at these at all so I don't know how
relevant they are.

Hope this helps.
