Understanding Annotated Source and Disassembly Data

Annotated source code and annotated disassembly code are useful for determining which source lines or instructions within a function are responsible for poor performance, and to view commentary on how the compiler has performed transformations on the code. This section describes the annotation process and some of the issues involved in interpreting the annotated code.

This chapter covers the following topics:

• How the Tools Find Source Code

• Annotated Source Code

• Annotated Disassembly Code

• Special Lines in the Source, Disassembly and PCs Tabs

• Viewing Source/Disassembly Without an Experiment
