val run : constant_defining_value Variable.Tbl.t -> initialize_symbol_field list Symbol.Tbl.t -> Flambda.constant_defining_value Symbol.Tbl.t -> the_dead_constant:Symbol.t -> allocation_point Variable.Map.tSimple alias analysis working over information about which symbols have been assigned to variables; and which constants have been assigned to symbols. The return value gives the assignment of the defining values of constants to variables. Also see comments for
Lift_constants, whose input feeds this pass.Variables found to be ill-typed accesses to other constants, for example arising from dead code, will be pointed at
the_dead_constant.
