    * optabs.h (trapv_unoptab_p): New function.
    (trapv_binoptab_p): Likewise.
    * optabs.c (expand_binop): Use emit_libcall_block_1 with
    a proper equiv_may_trap argument.
    (expand_unop): Likewise.
    (emit_libcall_block_1): Take extra argument whether the
    instruction may trap.  Renamed from ...
    (emit_libcall_block): ... this.  New wrapper.
