873 | Pragmatics: | |
874 | ||
875 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
876 | didn't scale. | |
877 | ||
878 | The more traditional mega-struct containing architecture specific | |
879 | data for all the various GDB components was also considered. Since | |
0fa6923a | 880 | GDB is built from a variable number of (fairly independent) |
