707 | /* Mechanism for co-ordinating the selection of a specific | |
708 | architecture. | |
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 JM |
727 | components it was determined that the global aproach was not |
728 | applicable. */ | |

732 | ||
733 | Register support for the specified ARCHITECTURE with GDB. When | |
734 | gdbarch determines that the specified architecture has been | |
735 | selected, the corresponding INIT function is called. | |

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 | |
ec3d358c | 750 | doesn't recognize the selected architecture; an existing \`\`struct |
104c1213 JM |

752 | architecture is just a synonym for an earlier architecture (see | |
753 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
