Can you add something to the effect of: This constant is a valid calling convention identifier (http://llvm.org/docs/LangRef.html#calling-conventions) for the version of LLVM used to generate the stackmap.  There are no additional compatibility guarantees made for this field over what LLVM provides elsewhere w.r.t. these indentifiers.
