           Summary: "operand missing mode" warning on sparc
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jimis@gmx.net
              Host: sparc-unknown-linux-gnu


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

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")

I do confirm "operand %d missing mode" warinings on my side (PowerPC
GNU/uClibc/Linux).

By the way, I can't remember how long since these warings are from... Maybe
4.2.x or even earlier.
