        * ravenscar-thread.h (ravenscar_register_arch_ops): Delete.
        * ravenscar-thread.c (current_arch_ops): Delete.
        (ravenscar_fetch_registers): Get the ravenscar_arch_ops
        from the gdbarch.
        (ravenscar_store_registers, ravenscar_prepare_to_store): Likewise.
        (ravenscar_inferior_created): Add gdbarch_ravenscar_ops check.
        (ravenscar_register_arch_ops): Delete.
        * ravenscar-sparc-thread.h: New file.
        * ravenscar-sparc-thread.c: #include "ravenscar-sparc-thread.h".
        (ravenscar_sparc_ops): Define value statically.
        (_initialize_ravenscar_sparc): Delete.
        (register_sparc_ravenscar_ops): New function.
        * sparc-tdep.c: #include "ravenscar-sparc-thread.h".
