Author: steven
Date: Mon Jul  9 08:45:12 2012
New Revision: 189366

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=189366
Log:
    * gensupport.c (init_rtx_reader_args_cb): Start counting code
    generating patterns from 1 to free up 0 for CODE_FOR_nothing.
    * gencodes.c (main): Give CODE_FOR_nothing the value 0.  Add
    the LAST_INSN_CODE marker at the end.
    * genoutput.c (nothing): New static struct data.
    (idata): Initialize to &nothing.
    (idata_end): Initialize to &nothing.next.
    (init_insn_for_nothing): New function to create dummy 'nothing' insn.
    (main): Use it.
    * genpeep.c (insn_code_number): Remove global variable.
    (gen_peephole): Take it as an argument instead.
    (main): Take insn_code_number from read_md_rtx.
    * optabs.h: Revert r161809:
    (optab_handlers): Change type of insn_code back to insn_code.
    (optab_handler, widening_optab_handler, set_optab_handler,
    set_widening_optab_handler, convert_optab_handler,
    set_convert_optab_handler, direct_optab_handler,
    set_direct_optab_handler): Remove int casts.
    Revert to treating the insn_code field as "insn_code".
