829 | per-architecture data. | |

834 | to maintain architecture specific data with gdbarch. |
835 | ||
836 | Pragmatics: | |
837 | ||
838 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
839 | didn't scale. | |
840 | ||
841 | The more traditional mega-struct containing architecture specific | |
842 | data for all the various GDB components was also considered. Since | |
0fa6923a | 843 | GDB is built from a variable number of (fairly independent) |
