Hi everyone,

I've been wasting hours trying to get my project to build, and nothing
seems to be working...

To summarize,

I copied the source code from:
http://clang.llvm.org/doxygen/arm__neon_8h-source.html

Into a file called "arm_neon.h"

added that to my project...

In the C++ file that is using intrinsics, I did #include "arm_neon.h"

When I build, I get a bunch of errors "Use of undeclared identifier
'__builtin_neon_vaddl'; did you mean '__builtin_neon_vpaddl_v'?"

These errors are in the arm_neon.h file on the lines such as:

  // vector long add
  INTTYPES_WIDENING(vaddl, __builtin_neon_vaddl)

What am I doing wrong?  How do I get NEON intrinsics to properly build
in Xcode?

I am using Xcode 7.2.1
