A pass to do RPO deduction and propagation of function attributes.
Synopsis
Declared in <llvm/Transforms/IPO/FunctionAttrs.h>
class ReversePostOrderFunctionAttrsPass
: public OptionalPassInfoMixin<ReversePostOrderFunctionAttrsPass>Description
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.
