2175    GDB targets (*-tdep.c) can register an interest in a specific

2177    per-architecture data.
2178

2186    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2187    didn't scale.
2188
2189    The more traditional mega-struct containing architecture specific
2190    data for all the various GDB components was also considered.  Since

2210    pre-initialized with information obtained from INFO.ABFD or

2212    that the INFO.BYTE_ORDER is non-zero.
2213
2214    The INIT function shall return any of: NULL - indicating that it
2215    doesn't recognize the selected architecture; an existing ``struct
2216    gdbarch'' from the ARCHES list - indicating that the new
2217    architecture is just a synonym for an earlier architecture (see
2218    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2219    - that describes the selected architecture (see gdbarch_alloc()).
2220
