890 | ||
891 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
892 | didn't scale. | |
893 | ||
894 | The more traditional mega-struct containing architecture specific | |
895 | data for all the various GDB components was also considered. Since | |
0fa6923a | 896 | GDB is built from a variable number of (fairly independent) |
