1007    didn't scale.

1010    data for all the various GDB components was also considered.  Since

1030    information obtained from INFO.ABFD or the global defaults.
1031

1033    of all the previously created architures for this architecture
1034    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1035    values from the previously selected architecture for this
1036    architecture family.  The global ``current_gdbarch'' shall not be
1037    used.
1038
1039    The INIT function shall return any of: NULL - indicating that it
1040    doesn't recognize the selected architecture; an existing ``struct
1041    gdbarch'' from the ARCHES list - indicating that the new
1042    architecture is just a synonym for an earlier architecture (see
1043    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1044    - that describes the selected architecture (see gdbarch_alloc()).
1045
