[PATCH, i386]: Fix annoying "i386.md: operand 1 missing mode" warnings

[Uros Bizjak]

H.J.,

can you perhaps look at one remaining warning:

../../gcc-svn/trunk/gcc/config/i386/sse.md:12034: warning: operand 1 
missing mode?

This warning points to:

(define_insn "*avx_vzeroall"
   [(match_parallel 0 "vzeroall_operation"
     [(unspec_volatile [(const_int 0)] UNSPECV_VZEROALL)
      (set (match_operand 1 "register_operand" "=x")
           (match_operand 2 "const0_operand" "X"))])]
   "TARGET_AVX"
   "vzeroall"
   [(set_attr "type" "sse")
    (set_attr "modrm" "0")
    (set_attr "memory" "none")
    (set_attr "prefix" "vex")
    (set_attr "mode" "OI")])

Thanks,
Uros.
