GHC ARM Hackathon (Re: Haskell on ARM )
It may not be long before most of the computing world has gone mobile.

Would anybody be interested in a "GHC on ARM Hackathon" in San Diego this year? When is 6.10 estimated to come out? Do we really need to wait for it? Jeremy Apthorp said:
it'll also require that I significantly strip down the runtime system, as the current RTS won't fit in 4M
Do you have a plan for how to do this? Maybe we can invite a Simon to teach us the innards of the RTS and help guide us? Thanks, Greg

Definitely. (Conveniently, I live in La Jolla).

According to this Release plan, the plan to release 6.10 around ICFP2008. http://hackage.haskell.org/trac/ghc/wiki/Status/Releases We wouldn't need a final release to get started, just something where the back-end changes are in place and working. One important item from the release plan is: * GHC now uses libffi to implement parts of the FFI, replacing some of the home-grown and very architecture-specific code we had to do this. Amongst other benefits, this will ease the task of porting GHC in the future. And possibly: * Substantial changes to the back end are likely, now that John Dias is here as an intern. John Dias, Simon PJ, Norman Ramsey It sounds like the changes to libffi might already be in 6.9. So, maybe we can start now ? j.

Unfortunately that's a bit of a reach for me; I live in southern Ontario and will be in New York City from September to December. So, I will likely be unable to attend, though I'll certainly see if I can pull it off. I'd be paying out of pocket for the travel, unfortunately. I definitely want to contribute what I can to this project, both because I want its result and because I want to learn more about GHC and the RTS. As to waiting for 6.10, I won't be able to contribute much work here before late August anyway, by which point much of 6.10 will likely be solidified in the HEAD 6.9. Certainly there are experiments and other parts of the project that can be worked on while waiting for the 6.10 release in late September. I'll post the results of any experiments and any thoughts in the GHC-on-ARM wiki. Notably, a page on what devices the developers have comes to mind. Braden Shepherdson shepheb
