 948
 949    The more traditional mega-struct containing architecture specific
 950    data for all the various GDB components was also considered.  Since

 975    values from the previously selected architecture for this

 980    doesn't recognize the selected architecture; an existing ``struct
 981    gdbarch'' from the ARCHES list - indicating that the new
 982    architecture is just a synonym for an earlier architecture (see
 983    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
 984    - that describes the selected architecture (see gdbarch_alloc()).
