I wrote a program using MCUXpresso.
I found my code performs quite differently in different optimization settings. Is there any way to know what has been optimized while compiling the program?
Environment:
IDE: MCUXpresso 10.3.1
Compiler: arm-none-eabi-gcc
This describes the optimisation levels

(Also available in the docs supplied with MCUXpresso)
