GCCFSS
The GCC for SPARC Systems (GCCFSS) compiler uses GNU Compiler Collection's (GCC) front end with the Sun 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 Sun Studio compiler's back end. This greatly facilitates the porting of GCC-based applications to SPARC systems.
GCCFSS 4.2 adds a new functionality as a cross compiler; SPARC binaries can be generated on an x86 (or x64) machine running Solaris.
