Nope, llvm's .s output is only compatible with GAS and other at&t  
syntax assemblers.  It turns out that MASM syntax is highly ambiguous  
and MASM is not production quality for use by a compiler.  This is why  
visual studio doesn't go through it.  Long term, we'd like LLVM to be  
able to write out .o files directly, if you're interested in adding  
PECOFF support, that would be very nice :)
