Subject: 2003-09-24  Dave Brolley  <brolley@redhat.com>

        * frv.cpu (u-commit): New modelling unit for fr500.
        (mwtaccg): Use frv_ref_SI to reference ACC40Sk as an input operand.
        (commit-r): Use u-commit model for fr500.
        (commit): Ditto.
        (conditional-float-binary-op): Take profiling data as an argument.
        Update callers.
        (ne-float-binary-op): Ditto.
