761 | architecture. | |
762 | ||
763 | GDB targets (*-tdep.c) can register an interest in a specific | |
764 | architecture. Other GDB components can register a need to maintain | |
765 | per-architecture data. | |
766 | ||
767 | The mechanisms below ensures that there is only a loose connection | |
768 | between the set-architecture command and the various GDB | |
0fa6923a | 769 | components. Each component can independently register their need |
104c1213 JM |
770 | to maintain architecture specific data with gdbarch. |
771 | ||
772 | Pragmatics: | |
773 | ||
774 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
775 | didn't scale. | |
776 | ||
777 | The more traditional mega-struct containing architecture specific | |
778 | data for all the various GDB components was also considered. Since | |
0fa6923a | 779 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
780 | components it was determined that the global aproach was not |
