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
