[cfe-dev] Targeting ARM with Clang

[Daniel Dunbar]

Right, this is the most accurate answer.

The main answer to a lot of the questions posed in this thread is "no
one has done it yet". There is no real reason we can't support -arch
on non-Darwin, I just haven't done the driver work for it. As with
many things, it is on my TODO list, but it hasn't made it to the top.

As for supporting targeting ARM, my official position on this is:
 (a) Yes, you can kind of do it with -ccc-host-triple.
 (b) This isn't a supported usage model. If it works for you, great,
but I don't think we should tell users to try it.
 (c) We should do the universal driver work to create a real cross
compilation model that actually works.
