--- Comment #6 from Tom Tromey <tromey at sourceware dot org> ---
I tend to think the cris one is a bug in cgen.
In particular /gen-extract-case does:

   (if (> (length (sfmt-iflds sfmt)) 0)
       (string-append
        "    CGEN_INSN_WORD insn = "
        (if (adata-integral-insn? CURRENT-ARCH)
            "entire_insn;\n"
            "base_insn;\n"))
       "")

... but I think in this case, because the ifield
is constant, later code doesn't emit any use of 'insn'.
