Also (see #5603) if you say case 3 of - S# x -> ... - J# _ _ -> ... -(where S#, J# are the constructors for Integer) we don't want the + IS x -> ... + IP _ -> ... + IN _ -> ... +(where IS, IP, IN are the constructors for Integer) we don't want the simplifier calling findAlt with argument (LitAlt 3). No no. Integer literals are an opaque encoding of an algebraic data type, not of an unlifted literal, like all the others. |
