--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- We'd probably need to change decl_to_stack_part from hash_map<tree, size_t> to hash_map<unsigned, size_t> that would just map DECL_UIDs which have DECL_RTL_IF_SET equal to pc_rtx to the partition numbers, rather than from decl, or have some other mapping from DECL_UIDs that appear in the points to info vars back to the decls.
