In effect, these new analysis techniques enable the compiler to critique high level C or C++ source code in order to combine optimizations more judiciously for maximum effect. To describe how some of the latest optimization and analysis techniques work, we will examine the following leading edge techniques and illustrate their effect with demonstrative code fragments. This can manifest itself in a number of ways. Code might become stuck in a loop while polling hardware, multi-threaded code might exhibit strange behavior, or optimization might result in the removal of code that implements deliberate timing delays.
