We introduce compiler optimization report, a useful tool if you wish to speed up your program by looking at what the compiler failed to optimize.

We introduce compiler optimization report, a useful tool if you wish to speed up your program by looking at what the compiler failed to optimize.
We try to answer two questions related to compiler optimizations: how can you help the compiler do a better job and when does it make sense to do the compiler optimizations manually.
We investigate what are the techniques your compiler employs to make your loop run faster.
