Extended Description
On linux/ppc llvm 2.9 (using clang) generates assembler in darwin style that gnu as does not accept. A simple testcase with llvm and gcc output is attached.
It seems to be a simple case of ha16(x) versus x@ha and lo16(x) versus x@l where the formers are darwin style and latters gnu style. Using corresponding #defines and preprocessing clang's assembler will enable us to make a functioning program.
