| 882 | architecture. |
| 883 | |
| 884 | GDB targets (*-tdep.c) can register an interest in a specific |
| 885 | architecture. Other GDB components can register a need to maintain |
| 886 | per-architecture data. |
| 887 | |
| 888 | The mechanisms below ensures that there is only a loose connection |
| 889 | between the set-architecture command and the various GDB |
| 890 | components. Each component can independently register their need |
| 891 | to maintain architecture specific data with gdbarch. |
| 892 | |
| 893 | Pragmatics: |
| 894 | |
| 895 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It |
| 896 | didn't scale. |
| 897 | |
| 898 | The more traditional mega-struct containing architecture specific |
| 899 | data for all the various GDB components was also considered. Since |
| 900 | GDB is built from a variable number of (fairly independent) |
| 901 | components it was determined that the global aproach was not |
| 902 | applicable. */ |

| 906 | |
| 907 | Register support for the specified ARCHITECTURE with GDB. When |
| 908 | gdbarch determines that the specified architecture has been |
| 909 | selected, the corresponding INIT function is called. |
| 910 | |
| 911 | -- |
| 912 | |
| 913 | The INIT function takes two parameters: INFO which contains the |
| 914 | information available to gdbarch about the (possibly new) |
| 915 | architecture; ARCHES which is a list of the previously created |
| 916 | \`\`struct gdbarch'' for this architecture. |

| 918 | The INIT function parameter INFO shall, as far as possible, be |
| 919 | pre-initialized with information obtained from INFO.ABFD or |
| 920 | previously selected architecture (if similar). |
| 921 | |
| 922 | The INIT function shall return any of: NULL - indicating that it |
| 923 | doesn't recognize the selected architecture; an existing \`\`struct |
| 924 | gdbarch'' from the ARCHES list - indicating that the new |
| 925 | architecture is just a synonym for an earlier architecture (see |
| 926 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' |
| 927 | - that describes the selected architecture (see gdbarch_alloc()). |
| 928 | |
