The NEON_2_SSE.h file is intended to simplify ARM->IA32 porting It makes the correspondence (or a real port) between ARM NEON intrinsics (as defined in "arm_neon.h") header and x86 SSE(up to SSE4.2) intrinsic functions as defined in corresponding x86 compilers headers files
To take advantage of this file just include it in your project that uses ARM NEON intinsics instead of "arm_neon.h", complile it as usual and enjoy the result
