--- Comment #26 from Oleg Endo <olegendo at gcc dot gnu.org> ---
I don't think this is a 'target' issue, changed to 'other'.

I've just committed the following, which should fix the issue for 4.9.

http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=201513

    PR other/12081
    * recog.h (rtx (*insn_gen_fn) (rtx, ...)): Replace typedef with    new
    class insn_gen_fn.
    * expr.c (move_by_pieces_1, store_by_pieces_2): Replace argument
    rtx (*) (rtx, ...) with insn_gen_fn.
    * genoutput.c (output_insn_data): Cast gen_? function pointers to
    insn_gen_fn::stored_funcptr.  Add initializer braces.


Since 4.8 also uses C++ it could be backported.
