Detailed Description
A pass to do RPO deduction and propagation of function attributes.
This pass provides a general RPO or "top down" propagation of function attributes. For a few (rare) cases, we can deduce significantly more about function attributes by working in RPO, so this pass provides the complement to the post-order pass above where the majority of deduction is performed.
