Hi Rafael,

I don't get the risk here, why would that risk any output?

I can see that the @llvm.annotation intrinsics use metadata for text,
but they discard them on use. It may be simpler to get an MDNode and
convert it into text, but if the intrinsic is *always*
converted-or-fail, I don't understand how it could output any unwanted
values.

cheers,
