709
710 GDB targets (*-tdep.c) can register an interest in a specific
711 architecture. Other GDB components can register a need to maintain
712 per-architecture data.
713
714 The mechanisms below ensures that there is only a loose connection
715 between the set-architecture command and the various GDB
0fa6923a 716 components. Each component can independently register their need
104c1213
JM
717 to maintain architecture specific data with gdbarch.
718
719 Pragmatics:
720
721 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
722 didn't scale.
723
724 The more traditional mega-struct containing architecture specific
725 data for all the various GDB components was also considered. Since
0fa6923a 726 GDB is built from a variable number of (fairly independent)
104c1213

727 components it was determined that the global aproach was not

736
737 --
738
739 The INIT function takes two parameters: INFO which contains the
740 information available to gdbarch about the (possibly new)
741 architecture; ARCHES which is a list of the previously created
742 \`\`struct gdbarch'' for this architecture.
743
744 The INIT function parameter INFO shall, as far as possible, be
745 pre-initialized with information obtained from INFO.ABFD or
746 previously selected architecture (if similar). INIT shall ensure
747 that the INFO.BYTE_ORDER is non-zero.
748
749 The INIT function shall return any of: NULL - indicating that it
750 doesn't reconize the selected architecture; an existing \`\`struct
751 gdbarch'' from the ARCHES list - indicating that the new
752 architecture is just a synonym for an earlier architecture (see
753 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
754 - that describes the selected architecture (see gdbarch_alloc()).
755
756 The DUMP_TDEP function shall print out all target specific values.

758 multi-arch and non- multi-arch cases. */
