686 | ||
687 | GDB targets (*-tdep.c) can register an interest in a specific | |
688 | architecture. Other GDB components can register a need to maintain | |
689 | per-architecture data. | |
690 | ||

697 | ||
698 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
699 | didn't scale. | |
700 | ||
701 | The more traditional mega-struct containing architecture specific | |
702 | data for all the various GDB components was also considered. Since | |
703 | GDB is built from a variable number of (fairly independant) | |

727 | doesn't reconize the selected architecture; an existing \`\`struct | |
728 | gdbarch'' from the ARCHES list - indicating that the new | |
