968 | GDB targets (*-tdep.c) can register an interest in a specific | |
969 | architecture. Other GDB components can register a need to maintain | |
970 | per-architecture data. | |

104c1213 JM |
975 | to maintain architecture specific data with gdbarch. |
976 | ||
977 | Pragmatics: | |
978 | ||
979 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
980 | didn't scale. | |
981 | ||
982 | The more traditional mega-struct containing architecture specific | |
983 | data for all the various GDB components was also considered. Since | |
0fa6923a | 984 | GDB is built from a variable number of (fairly independent) |
