That's correct. MASM is too weak to represent even slightly non-trivial
program. In your particular case - LLVM IR can set up any alignment it
want. Also note the FIXME's in the X86IntelAsmPrinter.cpp wrt the

You might try to round up the alignment to the highest allowed value,
but this might be an overkill...
