Oracle Developer Studio, formerly named Oracle Solaris Studio, Sun Studio, Sun WorkShop, Forte Developer, and SunPro Compilers, is Oracle Corporation's flagship software development product for the Solaris and Linux operating systems. It includes optimizing C, C++, and Fortran compilers, libraries, and performance analysis and debugging tools, for Solaris on SPARC and x86 platforms, and Linux on x86/x64 platforms, including multi-core systems. Oracle Developer Studio is downloadable and usable at no charge; however, there are many security and functionality patch updates which are only available with a support contract from Oracle. Version 12.4 adds partial support for the C++11 language standard. All C++11 features are supported except for concurrency and atomic operations, and user-defined literals. Version 12.6 supports the C++14 language standard. Languages C C++ Fortran Supported architectures SPARC i86pc (x86 and x86-64) Components The Oracle Developer software suite includes: C, C++, and Fortran compilers and support libraries dbx and frontends lint A NetBeans-based IDE Performance Analyzer Thread analyzer Sun performance library Distributed make Compiler optimizations A common optimizing backend is used for code generation. A high-level intermediate representation called Sun IR is used, and high-level optimizations done in the iropt (intermediate representation optimizer) component are operated at the Sun IR level. Major optimizations include: Copy propagation Constant folding and constant propagation Dead code elimination Interprocedural optimization analysis Loop optimizations Automatic parallelization Profile-guided optimization Scalar replacement Strength reduction Automatic vectorization, with -xvector=simd OpenMP The OpenMP shared memory parallelization API is native to all three compilers. Code coverage Tcov, a source code coverage analysis and statement-by-statement profiling tool, comes as a standard utility. Tcov generates exact counts of the number of times each statement in a program is executed and annotates source code to add instrumentation. The tcov utility gives information on how often a program executes segments of code. It produces a copy of the source file, annotated with execution frequencies. The code can be annotated at the basic block level or the source line level. As the statements in a basic block are executed the same number of times, a count of basic block executions equals the number of times each statement in the block is executed. The tcov utility does not produce any time-based data. GCCFSS The GCC for SPARC Systems (GCCFSS) compiler uses GNU Compiler Collection's (GCC) front end with the Oracle Developer Studio compiler's code-generating back end. Thus, GCCFSS is able to handle GCC-specific compiler directives, while
