I don't think that makes much sense. Most of the time, the loops in a 
single source file will be quite different and need different explicit 
unroll instructions, if any. There is a reason why they only apply to 
the next loop in clang.

It's just that directives don't work very well in that context, and 
hence my initial suggestion to use attributes instead. I'm by no means 
married to that proposal, but I don't think directives are a good 
approach either.
