        * ia64-tdep.c (pseudo_regs): New enum that lists gr32-gr127, p0-p63,
        bof, and nat0-nat127 as pseudo-registers.
        (ia64_frame_cache): New struct used to cache frame info.
        (ia64_register_reggroup_p): New routine used to override default
        register grouping so registers without names are still saved and
        restored.
        (ia64_dwarf_reg_to_regnum): New routine to map gr32-gr127 to their
        pseudo values.
        (ia64_pseudo_register_read): New routine to read pseudo-registers.
        (ia64_pseudo_register_write): New routine to write pseudo-registers.
        (ia64_alloc_frame_cache): New routine to create a new
        ia64_frame_cache.
        (examine_prologue): Change prototype to add next_frame pointer.
        Assume frameless until otherwise proven.  Verify that the cfm for
        current frame matches the cfm that should occur for the prologues
        alloc insn and if equal, mark as not frameless.  At end of routine,
        if not frameless, calculate registers for the previous frame and store
        in the cache, if a cache is provided.
        (ia64_skip_prologue):  Use new prototype when calling examine_prologue
        and pass 0 for next_frame.
        (ia64_store_return_value): Change to use convert_typed_floating()
        instead of calling ia64_convert_to_raw().
        (ia64_extract_return_value): Change to use convert_typed_floating()
        instead of calling ia64_convert_to_virtual().
        (ia64_frame_cache): New routine to support new frame model.
        (ia64_frame_this_id, ia64_frame_prev_register): Ditto.
        (ia64_frame_sniffer): Ditto.

        (ia64_extract_struct_value_address): Change to issue error message.
        (ia64_frame_align): New routine to align sp.
        (ia64_push_dummy_call): New routine based on ia64_push_arguments().
        (ia64_push_arguments): Removed.  Logic moved to
        ia64_push_dummy_call().
        (ia64_push_return_address): Ditto.
        (ia64_unwind_dummy_id): New function.

        (ia64_gdbarch_init): Remove registering of deprecated functions that
        are no longer used.  Add registration of new gdbarch functions.
        Remove registering deprecated_write_sp.  Replace
        set_gdbarch_register_virtual_type() with set_gdbarch_register_type().
        Delete set_gdbarch_deprecated_register_convertible(),
        set_gdbarch_deprecated_register_convert_to_virtual(), and
        set_gdbarch_deprecated_register_convert_to_raw() calls.  Remove
        set_gdbarch_deprecated_register_size(),

        set_gdbarch_deprecated_register_virtual_size(),
        and set_gdbarch_deprecated_max_register_virtual_size() calls.
        Replace set_gdbarch_deprecated_extract_return_value() with
        set_gdbarch_extract_return_value().  Remove calls to:
        set_gdbarch_deprecated_saved_pc_after_call();
        set_gdbarch_deprecated_frame_chain(),
        set_gdbarch_deprecated_frame_saved_pc(),

        set_gdbarch_deprecated_frame_locals_address(),
        and set_gdbarch_deprecated_dummy_write_sp().
        Add set_gdbarch_convert_register_p(),
