Hi,

Does RVCT 3.1 compiler is intelligent enough to identify which part of code can be NEON optimized and compiled in NEON?

Does it also give instruciotns while compiling, whether the code can be better optimized if we hand code it in NEON?

Regards,

Yes, if you have the --remarks flag specified it will tell you what it has vectorized.
