486 | GDB targets (*-tdep.c) can register an interest in a specific | |

488 | per-architecture data. | |

497 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
498 | didn't scale. | |
499 | ||

501 | data for all the various GDB components was also considered. Since | |
502 | GDB is built from a variable number of (fairly independant) | |
