Excerpts from Simon Marlow's message of Sun Aug 25 12:56:06 -0700 2013:
You can arrange that all the indirections end up next to each other by putting them in a special section. Then you can traverse the contents of the section so long as you have a symbol at the beginning and the end, or something like that. There are other ways to do it, such as having the module initialisation code register something with the RTS.
If I understand correctly, this is not true if you do something like dynamic linking, in which case each dynamic library will have its own indirection region. So in that case, every library should register its boundary symbols with the RTS.
Yes, sorry I forgot to mention that. Alternatively having each module register its table might be easier. Cheers Simon
