883 | ||
884 | GDB targets (*-tdep.c) can register an interest in a specific | |
885 | architecture. Other GDB components can register a need to maintain | |
886 | per-architecture data. | |
887 | ||
888 | The mechanisms below ensures that there is only a loose connection | |
889 | between the set-architecture command and the various GDB | |

104c1213 JM |
891 | to maintain architecture specific data with gdbarch. |
892 | ||
893 | Pragmatics: | |
894 | ||
895 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
896 | didn't scale. | |
897 | ||
898 | The more traditional mega-struct containing architecture specific | |
899 | data for all the various GDB components was also considered. Since | |
0fa6923a | 900 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
901 | components it was determined that the global aproach was not |
