10990 * expr.c (expand_assignment): Fix up a typo in simplify_gen_subreg
10991 last argument when extracting from CONCAT. If either from_real or
10992 from_imag is NULL, use expansion through memory. If result is not
10993 a CONCAT and simplify_gen_subreg fails, try to simplify_gen_subreg
10994 the parts directly to inner mode, if even that fails, use expansion
10995 through memory.
