Question

I can examine the optimization using profiler, size of the executable file and time to take for the execution.

I can get the result of the optimization.
But I have these questions,

• How to get the optimized C code.
• Which algorithm or method used by C to optimize a code.

Thanks in advance.

Answer 1

you can get an idea of optimization using the option -fdump-tree-optimized with gcc .
and you’ll get an optimised file. you cannot run the code but using that you can get an idea of optimization . dont forget to include -O2 or -O3 or some other level.
