Subject: [PATCH] 2005-05-26  David Ung  <davidu@mips.com>

        * mips.igen (mips32r2, mips64r2): New ISA models.  Add new model
        tags to all instructions which are applicable to the new ISAs.
        (do_ror, do_dror, ROR, RORV, DROR, DROR32, DRORV): Add, moved from
        vr.igen.
        * mips3264r2.igen: New file for MIPS 32/64 revision 2 specific
        instructions.
        * vr.igen (do_ror, do_dror, ROR, RORV, DROR, DROR32, DRORV): Move
        to mips.igen.
        * configure.ac (mipsisa32r2*-*-*, mipsisa64r2*-*-*): Add new targets.
        * configure: Regenerate.
