unsigned int vn_ssa_aux::dfsnum

     SCC information.

tree vn_ssa_aux::expr

     Representative expression, if not a direct constant.

Referenced by simplify_binary_expression().

unsigned vn_ssa_aux::has_constants

     Whether the representative expression contains constants.

Referenced by simplify_binary_expression().

unsigned int vn_ssa_aux::low

unsigned vn_ssa_aux::needs_insertion

     Whether the SSA_NAME has no defining statement and thus an
     insertion of such with EXPR as definition is required before
     a use can be created of it.

unsigned vn_ssa_aux::on_sccstack

unsigned vn_ssa_aux::use_processed

     Whether the SSA_NAME has been value numbered already.  This is
     only saying whether visit_use has been called on it at least
     once.  It cannot be used to avoid visitation for SSA_NAME's
     involved in non-singleton SCC's.

tree vn_ssa_aux::valnum

     Value number. This may be an SSA name or a constant.

Referenced by create_component_ref_by_pieces(), DFS(), and vn_phi_eq().

unsigned int vn_ssa_aux::value_id

     Unique identifier that all expressions with the same value have.

Referenced by bitmap_find_leader(), create_component_ref_by_pieces(), DFS(), get_expr_type(), phi_translate_1(), and vn_nary_op_insert_into().
