It's well-known that employee turnover rates come as a high cost to companies, however very few discuss the true extended costs and the multiple ways that it impacts the business. It's important that successful business not only find the best employees, but keep them engaged as well.
Commonly, compilers generate code for a machine architecture augmented with operating system routines and run-time language support routines. To use such a program, a particular operating system must be used and a collection of run-time support routines (I/O, storage allocation, mathematical functions, etc.) must be available. The combination of
Turning on optimization flags makes the compiler attempt to improve the performance and/or code size at the expense of compilation time and possibly the ability to debug the program. The compiler performs optimization based on the knowledge it has of the program.
