670 | architecture. | |
671 | ||
672 | GDB targets (*-tdep.c) can register an interest in a specific | |
673 | architecture. Other GDB components can register a need to maintain | |
674 | per-architecture data. | |
675 | ||
676 | The mechanisms below ensures that there is only a loose connection | |
677 | between the set-architecture command and the various GDB | |
678 | components. Each component can independantly register their need | |
679 | to maintain architecture specific data with gdbarch. | |
680 | ||
681 | Pragmatics: | |
682 | ||
683 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
684 | didn't scale. | |
685 | ||
686 | The more traditional mega-struct containing architecture specific | |
687 | data for all the various GDB components was also considered. Since | |
688 | GDB is built from a variable number of (fairly independant) | |
689 | components it was determined that the global aproach was not | |

694 | ||

696 | gdbarch determines that the specified architecture has been | |
697 | selected, the corresponding INIT function is called. | |
698 | ||
699 | -- | |
700 | ||
701 | The INIT function takes two parameters: INFO which contains the | |
702 | information available to gdbarch about the (possibly new) | |
703 | architecture; ARCHES which is a list of the previously created | |
704 | \`\`struct gdbarch'' for this architecture. | |

706 | The INIT function parameter INFO shall, as far as possible, be | |
707 | pre-initialized with information obtained from INFO.ABFD or | |
708 | previously selected architecture (if similar). INIT shall ensure | |
709 | that the INFO.BYTE_ORDER is non-zero. | |
710 | ||
711 | The INIT function shall return any of: NULL - indicating that it | |
712 | doesn't reconize the selected architecture; an existing \`\`struct | |
713 | gdbarch'' from the ARCHES list - indicating that the new | |
714 | architecture is just a synonym for an earlier architecture (see | |
715 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
716 | - that describes the selected architecture (see gdbarch_alloc()). |
717 | ||
718 | The DUMP_TDEP function shall print out all target specific values. | |
719 | Care should be taken to ensure that the function works in both the | |
720 | multi-arch and non- multi-arch cases. */ | |
