Here is some GCC benchmarks of real-life scenarios.
There are three applications (A,B,C) built for cortex-m3 ARM architecture using
several GCC versions with two optimisation sets (Debug (D) and Release (R)).
One may find the details in attached file [GCC_Benchmarks.txt];
Here is an summary of Application C build artifacts.
