regarding C6000 compiler optimization

Hi All

In the process of doing optimization of cycle count..

Initially I set optimization level as -O3 in Build ->C6000 compiler ->optimization. cycle count reduced to a decent number.

But i wanted to optimize cycles further.

Thus I also set 'optimize for speed' level as 5(Build ->C6000 compiler->Advanced options ->Advanced Optimizations), along with -O3.

Then cycle count reduced to the expected cycle count :)

My question is : what is the difference between -O3 and 'optimize for speed' level 5?

'optimize for speed' does cycle count optimization??

Please answer to my question.

Thanks & Regards

Veera
