            Bug ID: 63905
           Summary: redundant fields left in gcc/cp/cp-tree.h:lang_decl_fn
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

svn commit 201994 (git commit fc3dabd5) changed
DECL_CONSTRUCTOR_P/DECL_DESTRUCTOR_P to use middle-end flags instead of
frontend flags however it didn't remove the now obsolete (unused) c++ frontend
flags constructor_attr and destructor_attr from lang_decl_fn. fixing this would
also free up 2 bits where there's only one left now.
