Hi,Sir, S32 design studio for power architecture version 2017.r1 compiler optimization level O1, what specific optimization has been done, and can optimization be enabled?

Found in the actual project: 1 For the same 200m main frequency, mpc5744 takes more than twice as long as tc275!!!

2. However, when the optimization above O1 is enabled, the operation efficiency is significantly improved

Hi, 

s32ds uses gcc compiler - the optimization level description you can find here:
