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 it is also able to take advantage of the compiler optimizations in the compiler's back end. This greatly facilitates the porting of GCC-based applications to SPARC systems.

GCCFSS 4.2 adds the ability to be used as a cross compiler; SPARC binaries can be generated on an x86 (or x64) machine running Solaris.

Research platform

Before its cancellation, the Rock would have been the first general-purpose processor to support hardware transactional memory (HTM). The Oracle Developer Studio compiler is used by a number of research projects, including Hybrid Transactional Memory (HyTM) and Phased Transactional Memory (PhTM), to investigate support and possible HTM optimizations.
