811 architecture.
812
813 GDB targets (*-tdep.c) can register an interest in a specific
814 architecture. Other GDB components can register a need to maintain
815 per-architecture data.
816
817 The mechanisms below ensures that there is only a loose connection
818 between the set-architecture command and the various GDB
819 components. Each component can independantly register their need
820 to maintain architecture specific data with gdbarch.
821
822 Pragmatics:
823
824 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
825 didn't scale.
826
827 The more traditional mega-struct containing architecture specific
828 data for all the various GDB components was also considered. Since
829 GDB is built from a variable number of (fairly independant)
830 components it was determined that the global aproach was not
831 applicable. */

834/* Register a new architectural family with GDB.
835
836 Register support for the specified ARCHITECTURE with GDB. When
837 gdbarch determines that the specified architecture has been
838 selected, the corresponding INIT function is called.
839
840 --
841
842 The INIT function takes two parameters: INFO which contains the
843 information available to gdbarch about the (possibly new)
844 architecture; ARCHES which is a list of the previously created
845 ``struct gdbarch'' for this architecture.
846
847 The INIT function parameter INFO shall, as far as possible, be
848 pre-initialized with information obtained from INFO.ABFD or
849 previously selected architecture (if similar). INIT shall ensure
850 that the INFO.BYTE_ORDER is non-zero.
851
852 The INIT function shall return any of: NULL - indicating that it
853 doesn't reconize the selected architecture; an existing ``struct
854 gdbarch'' from the ARCHES list - indicating that the new
855 architecture is just a synonym for an earlier architecture (see
856 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
857 - that describes the selected architecture (see
858 gdbarch_alloc()). */
