It is certainly possible, but considered as not desirable.
As an engineer I can say that it wouldn't be too difficult to do the x86,
but I don't think it will happen any time soon.

Personally I'd like to arrange it as a gcc branch or contribute it
in some way, but my previous effort of much smaller scale (gcc2c) had
quite negative reception, so I don't expect any sort of approval.

Also I'd like to emphasize that "GCC for SPARC Systems" is trying to deliver
performance on SPARC cpus to those users who use plain GCC compiler there.
That's it.

I tried to explain my personal opinion of "gcc4ss vs gcc on sparc" on my blog:

Please don't hesitate to ask questions.
I'll be glad to share the details of implementation and hope that few things
may be useful to GCC developers as well.

Thank you.
