Re: Compiling with GCC optimizations disabled

[Rania_d]

Hi, The gcc option -O enables different levels of optimization. Use -O0 to 
disable them and use -S to output assembly. -O3 is the highest level of 
optimization. Starting with gcc 4.8 the optimization level -Og is available. It 
enables optimizations that do not interfere with debugging and is the 
recommended default for the standard edit-compile-debug cycle.
