This manual describes the performance and analysis tools available with Sun WorkShop(TM). Developing high performance applications requires a combination of compiler features, libraries of optimized routines, and tools to analyze and isolate code. Analyzing Program Performance With Sun WorkShop describes the third part of this development strategy, and shows you how to use these tools:
The Sampling Analyzer and Sampling CollectorLoopTool and LoopReportLockLintprof, gprof, and tcov
"Related Books" lists sources for information about Sun WorkShop compilers and performance libraries.
This manual is intended for programmers with a working knowledge of Sun WorkShop and some understanding of the Solaris(TM) operating environment and UNIX\256 commands. Some knowledge of performance analysis is also helpful in understanding how to use the data derived from the tools, but is not required for using them. The traditional profiling tools prof, gprof, and tcov, do not require a working knowledge of Sun WorkShop.
Chapter 1, "Performance Profiling and Analysis Tools," introduces the performance analysis tools, briefly discussing what they do and when to use them.
Chapter 2, "The Sampling Analysis Tools," describes the Sampling Collector and the Sampling Analyzer. You can use these tools to help you improve your program's use of resources.
Chapter 3, "Loop Analysis Tools," presents LoopReport and LoopTool, which help you analyze program loops that have been parallelized by your compiler.
Chapter 4, "Traditional Profiling Tools," covers the traditional profiling tools prof, gprof, and tcov, which help you find the parts of your program that are most heavily used, and determine how much of your program is being tested.
Chapter 5, "Lock Analysis Tool," documents LockLint, which assists you in analyzing locks and potential race conditions in multi-threaded programs.
Appendix A, "LockLint Command Reference," provides reference-style information on the LockLint commands.
The name of the latest Solaris operating environment release is Solaris 7 but code and path or package path names may use Solaris 2.7 or SunOS 5.7.
The Sun(TM) WorkShop(TM) documentation applies to Solaris 2.5.1, Solaris 2.6, and Solaris 7 operating environments on:
The SPARC(TM) platform
The x86 platform, where x86 refers to the Intel implementation of one of the following: Intel 80386, Intel 80486, Pentium, or the equivalent
The term "x86" refers to the Intel 8086 family of microprocessor chips, including the Pentium, Pentium Pro, and Pentium II processors and compatible microprocessor chips made by AMD and Cyrix. In this document, the term "x86" refers to the overall platform architecture. Features described in this book that are particular to a specific platform are differentiated by the terms "SPARC" and "x86" in the text.
