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.

'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.
