About 10 years ago, Rask Ingemann Lambertsen sent a patch series to add
a 16-bit x86 (i.e. 8088, 8086, 80186 and 80286 CPUs) back end. This work
was never committed. Recently I've been doing some work on this back
end, and today we released a Sourcery CodeBench Lite distribution based
on it (see
https://blogs.mentor.com/embedded/blog/2017/04/01/announcing-sourcery-codebench-lite-for-ia16/
). Given this, I thought it would be a good idea to send these patches
upstream today (though obviously if I commit these it won't be until
we're in Stage 1 and more testing has been done on the middle-end changes).
I have not been able to contact Rask Ingemann Lambertsen, but he does
have a copyright assignment for GCC on file (dated 2006-11-16) so I do
not believe there are any copyright assignment issues that would block
this.
Note that with the trunk in stage4 and a release rapidly approaching,
it's unlikely that anyone will be looking in depth at this until after
the release branch is cut.
