Inlining of methods (dictionary accessors) in GHC 7.10?

Did something about change with method inlining between GHC 7.8.2 and 7.10.3? I don't mean methods attached to instances, but rather the method name itself, which I understand is defined as simple field accessors into a dictionary. I do inlining indirectly via HERMIT, and the method names are no longer successfully inlining to the accessors. The dictionaries themselves inline fine, as do field accessors for algebraic types with named fields. -- Conal
