--- Comment #37 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So the remaining issue is that for one function emitted in the
-fdump-final-insns= the cgraph uid is the same, but symbol_order= is different
(on the testcase by 1). This is the function with the highest node->order in
the file, so potentially it could affect more than that.
So, if we really want to make sure that node->order is the same regardless of
GC, we should either make sure the cgraph nodes for the constexpr function
copies needed for constexpr processing aren't created at all, or ae always
created freshly (e.g. by unregistering the cgraph nodes for them when we put
them into the freelist), or perhaps just by making sure we always update the
order. Let me find out where exactly is the cgraph node creation called from.
