[Lightning] Using Lightning for iOS

[Iain Merrick]

Hi lightning folks,

Good to see there's some recent activity on this list, and discussion
of Lightning 2.0!

I'm interesting in writing some JIT-based code to target iOS. Apple
imposes some heavy restrictions on dynamic code generation, so it
occurs to me that Lightning be a better fit than LLVM, as Lightning is
much simpler and should be easier to tweak. (The main requirement
seems to be setting code pages to r-x before trying to execute them;
rwx is banned. Good explanation here: good summary here:
http://www.stuartcarnie.com/2011/03/executable-pages-in-ios-43.html)

What's the current level of ARM support?
http://www.gnu.org/software/lightning/ says "the available backends
cover the i686, x86_64, mips, arm, ppc, and sparc architectures", but
links to the download for Lightning 1.2, which only seems to contain
i386, ppc and sparc. Is there newer code somewhere?

Thanks!

Iain
