-For Solaris/SPARC, LLVM only supports the SPARC V9 architecture.  Therefore,
-the configure command line should specify sparcv9, as shown below. Also,
+The GCC front-end can be configured for either SPARC V8 (32 bit) or SPARC V9 (64

+The SPARC V8 backend is still beta quality software.  Unless you are working on
+the SPARC V8 backend, you should specify sparcv9 on the configure command line,
