[cfe-dev] clang sparc backend

It sounds as if the sparc back end is not using the integrated assembler 
and so it will call out to the default assembler for your toolchain. 
Because you have not specified a -B option, the default search path will 
be /usr/bin, where it is finding an assembler.  This assembler, 
unfortunately, cannot handle SPARC assembly (it sounds as if it's an 
x86-64 build of gas).

If you want to assemble the output from clang, you will need to install 
a SPARC assembler (and, for it to be useful, also install a SPARC 
linker) and specify -B {path/to/tools} in the flags that you pass to clang.
