Subject:         * interp.c (hash): Fix.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=83fc3bac9fd75bd785cf0016ca429b301c30fabd;p=binutils-gdb.git

    * interp.c (hash): Fix.
        * interp.c (do_format_8): Get operands correctly and
        call the target function.
        * simops.c: Rough cut at "clr1", "not1", "set1", and "tst1".
