Leon is a conforming implementation of the SPARC V7/V8 architecture so it 
should be possible to support it alongside the other SPARC implementations in 
the SPARC back-end of the mainline compiler.  I'd be happy to review patches 
to this effect (and I presume the other SPARC maintainers are OK with this).

So I'd suggest that Luís Vitório and/or Konrad do the required paperwork, and 
then start to post their patches on the gcc-patches@ list.  I'll sponsor them 
for write access at that point.
