<p>
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
bit). This changes, among other things, the sizes of integer types and the
macros defined for conditional compilation.

<p>
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,
as shown below. Also,
note that Solaris has trouble with various wide (multibyte) character
functions from C as referenced from C++, so we typically configure with
--disable-c-mbchar (cf. <a href="http://llvm.cs.uiuc.edu/PR206">Bug 206</a>).
