Just a side note for people who may be interested in creating high performance code to take advantage on NEON instruction set but wish to use NEON intrinsic instaed of coding assembly.
Compiler won't generate NEON opcode unless application use the NEON intrinsic explicitly.

Basically, you need ARMv7 build enviroment, so compiler can emit NEON opcode.
Intrinsic prototype can be found in public\COMMON\sdk\inc\arm_neon.h and that is all you got.
If you ever find an NEON opcode does not have corresponding intrinsic, you still need to use the old trick - write that part of code in assembly.
