Sun Studio
From Cppwiki
Sun Studio (formerly Sun WorkShop, Forte Developer and Sun ONE Studio) is a compiler and IDE for Solaris and Linux platforms released by Sun Microsystems. Until version 12 (currently in beta), Studio only provided a compiler on Solaris; the Linux version was purely an IDE and debugger. Version 12 will include a C/C++/Fortran compiler for both platforms. Studio is free to use for both non-commercial and commercial use; Sun offers paid support for commercial users.
Although a capable C compiler, Studio C++ is a fairly limited C++ compiler, having problems with several features of the C++ language. Improvements have been made with Studio 10 and 11, and the development team is currently working on improving Boost compatibility in the compiler, leading to overall better C++ support.
Studio C++ provides two standard libraries: the Rogue Wave standard library (default), an old version of the Rogue Wave library for binary compatibility with older versions of the compiler, and STLport.
Studio is the preferred compiler for SPARC platforms, usually providing noticably better performance than GCC.
