Someone may have been thorough when adding arches to certain 
files, but that in no way implies much actual support.  The gdc 
section of the download page claims sparc support, so you could 
look at what they've done.

You may be able to combine the existing Solaris support and the 
sparc backend of llvm or gcc and get pretty far.  A lot of the 
work should just be translating headers needed for the 
solaris/sparc sections in druntime.  You could look at the 
linux/powerpc work Kai did with ldc for an idea of the changes 
necessary for a new arch.

As kagamin said, dmd's backend is i386/x86_64 only, so you have 
to use ldc or gdc.
