your messy code in and get a nice optimized binary out. The hallway philosophers
will often start a debate on which language features or compiler flags to use
in order to capture the full power of the compiler’s magic.
If you have ever seen the GCC codebase, you would really believe it must be doing
some magical optimizations coming from another planet.
Nevertheless, if you analyze the compiler’s output you will found out that
the compilers are not really that great at optimizing your code. Not because
