| The INIT function takes two parameters: INFO which contains the |
| information available to gdbarch about the (possibly new) |
| architecture; ARCHES which is a list of the previously created |
| \`\`struct gdbarch'' for this architecture. |
| |
| The INFO parameter is, as far as possible, be pre-initialized with |
| information obtained from INFO.ABFD or the previously selected |
| architecture. |
| |
| The ARCHES parameter is a linked list (sorted most recently used) |
| of all the previously created architures for this architecture |
| family. The (possibly NULL) ARCHES->gdbarch can used to access |
| values from the previously selected architecture for this |
| architecture family. The global \`\`current_gdbarch'' shall not be |
| used. |
| |
| The INIT function shall return any of: NULL - indicating that it |
| doesn't recognize the selected architecture; an existing \`\`struct |
| gdbarch'' from the ARCHES list - indicating that the new |
| architecture is just a synonym for an earlier architecture (see |
| gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' |
| - that describes the selected architecture (see gdbarch_alloc()). |
| |
| The DUMP_TDEP function shall print out all target specific values. |
| Care should be taken to ensure that the function works in both the |
| multi-arch and non- multi-arch cases. */ |
