Hi Edwin,

 The current subversion trunk produces _mostly_ working 32-bit SPARC code now with llvm-gcc, but as noted above it doesn't quite bootstrap gcc yet - there are still some bugs in the generated code. Which is to say, it's not at production level yet. I haven't tested clang, but I would expect it to behave similarly.

 I'd also like to see SPARC JIT working, but I don't know when/if anyone will have time to do the work.
