Sun Studio 8 New Features

Sun Studio 8 replaces the Sun ONE Studio 8, Compiler Collection. The Sun ONE Studio 8, Compiler Collection was a command-line only release of the C, C++, and Fortran compilers, libraries, and tools. Sun Studio 8 includes the same compilers and libraries released with the Sun ONE Studio 8, Compiler Collection release and adds an Integrated Development Environment (IDE) and an updated Performance Analyzer.

This chapter describes the following new Sun Studio 8 features.

Integrated Development Environment (IDE)

Performance Analysis Tools

Documentation

The Sun Studio 8 release includes the following compilers, libraries, and tools that are unchanged from the Sun ONE Studio 8, Compiler Collection release. New features for the compilers, libraries, and tools released with the Sun ONE Studio 8, Compiler Collection are described in Chapter 2.

C Compiler

C++ Compiler

Fortran Compiler

dbx Command-Line Debugger

Sun Performance Library

Interval Arithmetic

In most sections, there is a table that lists the new features of that component. The table has either two columns or three columns:

Two-column table. The left-hand column provides a short description of the feature, and the right-hand column has a longer description.

Three-column table. The left-hand column provides a short description of the feature, the middle column lists the relevant command or option, and the right-hand column has a longer description of the new feature.

Note - To find the Sun Studio 8 documentation described in this chapter, see the documentation index installed with the product software at /opt/SUNWspro/docs/index.html. If your software is not installed in the /opt directory, contact your system administrator for the equivalent path on your system or network.

Integrated Development Environment (IDE)

The Sun Studio 8 IDE provides modules for creating, editing, building, debugging, and analyzing the performance of a C, C++, or Fortran application. It includes a set of basic Java language support modules that can be enabled if needed for JNI (Java Native Interface) development.

This release of the IDE is available on the Solaris Operating System (Solaris OS) (SPARC Platform Edition) versions 7, 8, and 9; and the Solaris OS (x86 Platform Edition) versions 7, 8, and 9.

The Sun Studio 8 software consists of two major components:

The Sun Studio component, which includes the IDE, compilers, tools, and core platform

The Java 2 Platform, Standard Edition (J2SE) technology on which the Core Platform runs

The Sun Studio 8 component is installed by default in the /opt directory, but an alternate location can be specified during installation. The J2SE technology is installed by default in the /usr/jdk/j2sdk1.4.2_02 directory, but an alternate directory in /usr can be specified during installation.

The correct operation of the IDE depends IDE being able to find the core platform, and the core platform being able to find the J2SE technology.

Starting the IDE

The command to start the IDE is sunstudio. For details on this command, see the sunstudio(1) man page. (To display the sunstudio(1) man page, you must have /installation-directory/SUNWspro/man in your $MANPATH.)

Performance Analysis Tools

The following sections list the new data collection and presentation features in the Sun Studio 8, release of the performance analysis tools. For more information, see the following man pages:

analyzer(1)

collect(1)

collector(1)

er_print(1)

libcollector(3)

Data collection features

The following list describes new or changed data collection capabilities.

The Performance Analyzer can now be used as a NetBeans module, integrated into the IDE, as well as a command from the shell.

The Performance Analyzer now has a Collector window that allows selection of and recording of experiments from the GUI.

Data collection error detection and reporting have been enhanced.

For more information, refer to the collect(1), collector(1) and libcollector(3) man pages.

Data presentation features

The following list describes new or changed data presentation capabilities.

The Performance Analyzer shows a tick mark next to the scrollbar for annotated source and disassembly, indicating high-metric lines.

The Performance Analyzer has additional flexibility in setting colors for functions in the timeline.

The Performance Analyzer has additional flexibility in showing clock profiling data in the timeline for CPU idle states

er_print and the Performance Analyzer now can coalesce data types from different object files, so that the type reports and displays do not show repeated entries for the same structure. The er_print formatting of the report for an object type is improved. A new data_layout er_print command and corresponding Analyzer tab were implemented.

er_print now has an improved help message, with the commands listed in the same order as they appear on the man page.

For more information, refer to the analyzer(1) and er_print(1) man pages and the Performance Analyzer online help.
