804 | architecture. | |
805 | ||
806 | GDB targets (*-tdep.c) can register an interest in a specific | |
807 | architecture. Other GDB components can register a need to maintain | |
808 | per-architecture data. | |
809 | ||
810 | The mechanisms below ensures that there is only a loose connection | |
811 | between the set-architecture command and the various GDB | |
0fa6923a | 812 | components. Each component can independently register their need |
104c1213 JM |
813 | to maintain architecture specific data with gdbarch. |
814 | ||
815 | Pragmatics: | |
816 | ||
817 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
818 | didn't scale. | |
819 | ||
820 | The more traditional mega-struct containing architecture specific | |
821 | data for all the various GDB components was also considered. Since | |
0fa6923a | 822 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
823 | components it was determined that the global aproach was not |

828 | ||
829 | Register support for the specified ARCHITECTURE with GDB. When | |
830 | gdbarch determines that the specified architecture has been | |
831 | selected, the corresponding INIT function is called. | |
832 | ||
833 | -- | |
834 | ||
835 | The INIT function takes two parameters: INFO which contains the | |
836 | information available to gdbarch about the (possibly new) | |
837 | architecture; ARCHES which is a list of the previously created | |
838 | \`\`struct gdbarch'' for this architecture. | |
839 | ||
0f79675b | 840 | The INFO parameter is, as far as possible, be pre-initialized with |
7a107747 | 841 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
842 | |
843 | The ARCHES parameter is a linked list (sorted most recently used) | |
844 | of all the previously created architures for this architecture | |
845 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
846 | values from the previously selected architecture for this | |
847 | architecture family. The global \`\`current_gdbarch'' shall not be | |
848 | used. | |
104c1213 JM |
849 | |
850 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 851 | doesn't recognize the selected architecture; an existing \`\`struct |
104c1213 JM |
852 | gdbarch'' from the ARCHES list - indicating that the new |
853 | architecture is just a synonym for an earlier architecture (see | |
854 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
855 | - that describes the selected architecture (see gdbarch_alloc()). |
856 | ||
