This isn't actually an error of transposition for Sparc/SunOS when using 
the "cc" compiler. This "save -96, %o6, %o6" (and the .bss section 
identifier) work when using SunOS "cc" but not "gcc" under SunOS.

My patches will assume that everyone is using "cc" under SunOS...because 
we can't check in llc whether someone will use "cc" or "gcc" to assemble 
and link in the future ;)

Thanks,
Kelly Wilson

P.S. I will post patches to llvm-dev.
