[LLVMdev] SSE intrinsic alignment bug?

[Dale Johannesen]

The intent here is that "in" and "out" are always aligned, by forcing  
the stack pointer in the function that defines them to be aligned.  On  
some targets (darwin) the stack pointer is always 16-byte aligned; on  
other targets there should be code in the function prologue to force  
it to be aligned.
