Optimizing XL compiler applications

The XL compilers provide a powerful portfolio of optimizing transformations available on an array of supported hardware and operating system platforms. The following sections provide background information on the portfolio, guidance on using the optimization features of the XL compiler family, and details some common optimization techniques and transformations. For best results, defer optimization until after thorough debugging and testing of your application. To better prepare your code for the optimization process, consult Compiler-friendly Programming Techniques.
