About this book

The ARM® Compiler Compiler User Guide provides information for users new to ARM Compiler 6.

Using this book

This book is organized into the following chapters:

Chapter 1 Getting Started

This introduces ARM® Compiler 6 and helps you start working with ARM Compiler 6 quickly. You can use ARM Compiler 6 from ARM DS-5, Keil MDK, or as a standalone product.

Chapter 2 Using Common Compiler Options

There are many options that you can use to control how ARM® Compiler 6 generates code for your application. This section lists the mandatory and commonly used optional command-line arguments, such as to control target selection, optimization, and debug view.

Chapter 3 Writing Optimized Code

To make best use of the optimization capabilities of ARM® Compiler, there are various options, pragmas, attributes, and coding techniques that you can use.

Chapter 4 Using Assembly and Intrinsics in C or C++ Code

All code for a single application can be written in the same source language. This is usually a high-level language such as C or C++ that is compiled to instructions for ARM® architectures. However, in some situations you might need lower-level control than what C and C++ provide.

Chapter 5 Mapping Code and Data to the Target

There are various options in ARM® Compiler to control how code, data and other sections of the image are mapped to specific locations on the target.

Appendix A Supporting reference information

The various features in ARM Compiler might have different levels of support, ranging from fully supported product features to community features.
