Hi everyone,
I am using CCS 6.13 for my project. I was unable to make optimization option work. here is my setting in CCS:
it seems the configuration is done, but it did not seems to work. I had this issue when I used debug mode, and it worked when I used Release mode.( the execution time of one of my fuctions significantly reduced when it is working.). Now even if in Release model, it is not working any more. the performance advice file says the -g should be removed. as you can see in second image, no -g option there. following is the part of the performance advice file:

what could prevent optimization option working?
your help is highly appreciated!
