llvm-gcc on OpenSolaris for SPARC

Dear All,

Is anyone using llvm-gcc and LLVM on OpenSolaris compiling for the SPARC
architecture? I see that it's listed under supported platforms, but I
don't see a pre-built llvm-gcc front-end for it.

I know someone here at Illinois that needs it, but I'd like to know if
compiling llvm-gcc is likely to work before I try it.

Thanks in advance.

If it works, could you post instructions or make the binary available (if
there is anything special to be done)? Thanks!
