           Summary: "operand missing mode" warning on sparc
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target

I get the following warnings while building gcc on a sparcstation:

build/genrecog ../../gcc-trunk-109439-co/gcc/config/sparc/sparc.md \
  insn-conditions.md > tmp-recog.c
../../gcc-trunk-109439-co/gcc/config/sparc/sync.md:82: warning: operand 1
missing mode?
../../gcc-trunk-109439-co/gcc/config/sparc/sync.md:94: warning: operand 1
missing mode?



The relevant lines of sync.md are:

     82 (define_insn "*sync_compare_and_swap<mode>"
     83   [(set (match_operand:I48MODE 0 "register_operand" "=r")
     84         (mem:I48MODE (match_operand 1 "register_operand" "r")))
     85    (set (mem:I48MODE (match_dup 1))
     86         (unspec_volatile:I48MODE
     87           [(match_operand:I48MODE 2 "register_operand" "r")
     88            (match_operand:I48MODE 3 "register_operand" "0")]
