721 architecture.
722
723 GDB targets (*-tdep.c) can register an interest in a specific
724 architecture. Other GDB components can register a need to maintain
725 per-architecture data.
726
727 The mechanisms below ensures that there is only a loose connection
728 between the set-architecture command and the various GDB
0fa6923a 729 components. Each component can independently register their need
104c1213
JM
730 to maintain architecture specific data with gdbarch.
731
732 Pragmatics:
733
734 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
735 didn't scale.
736
737 The more traditional mega-struct containing architecture specific
738 data for all the various GDB components was also considered. Since
0fa6923a 739 GDB is built from a variable number of (fairly independent)
104c1213
JM
740 components it was determined that the global aproach was not
741 applicable. */

748 selected, the corresponding INIT function is called.
749
750 --
751
752 The INIT function takes two parameters: INFO which contains the
753 information available to gdbarch about the (possibly new)
754 architecture; ARCHES which is a list of the previously created
755 \`\`struct gdbarch'' for this architecture.
756
757 The INIT function parameter INFO shall, as far as possible, be
758 pre-initialized with information obtained from INFO.ABFD or
759 previously selected architecture (if similar). INIT shall ensure
760 that the INFO.BYTE_ORDER is non-zero.
761
762 The INIT function shall return any of: NULL - indicating that it
ec3d358c 763 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
764 gdbarch'' from the ARCHES list - indicating that the new
765 architecture is just a synonym for an earlier architecture (see
766 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
767 - that describes the selected architecture (see gdbarch_alloc()).
768
769 The DUMP_TDEP function shall print out all target specific values.
