I have a tool chain for an experimental processor, built starting with release or snapshot distributions of
binutils-2.21 cgen-20110901 gcc-4.6.1 newlib-1.19.0 gdb 7.2 I'm using SVN for version control locally. I'd like to upgrade it to a newer source base; but since it wasn't done by checking out from the FSF and Sourceware version-control systems, I'm wondering if there's any clever way to merge my tree or if I just have to bite the bullet and essentially take everything I've modified since version 1 in my source tree and import them into a new source tree?
