[rust-dev] iOS cross compilation

Hi, So finally Rust can cross-compile for iOS (armv7 only for now). BTW, it also means that Rust now can be used both for iOS and Android low-level development. Short instructions are available here: https://github.com/mozilla/rust/wiki/Doc-building-for-ios Unfortunately LLVM patch for supporting segmented stacks on armv7 was declined by Apple (it used kind of private API) and therefore there is no stack protection at all. It still could be enabled by compiling with a patched LLVM (I can provide a patch and instructions if needed). Everything else should "just work" but let me know if you have any problem. -- Valerii
