Yes, it works (except for wget not being available, which can easily be solved by using curl). Here is the script I ran and the assembly file it generates: http://people.freedesktop.org/~ranma42/ios-neon-asm/ I'm running XCode 4.2.1, which ships with: $ clang --version Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn) Target: x86_64-apple-darwin11.3.0 Thread model: posix I just noticed that there is also a newer XCode version (4.3). I'll upgrade and check if anything breaks.
