This major open-source drop includes documentation, the complete development stack, which consists of the compiler itself, debugger, assembler, run-time, and standard libraries. While the compiler is now open-source, PathScale will continue to offer paid support for EKOPath as well as support options for AMD's Open64 compiler.
PathScale is using the GNU GPL license.
The EKOPath compiler has been popular within the industry and for those specialized in HPC (High Performance Computing) as this compiler suite is designed to deliver sheer speed on modern Intel and AMD hardware. EKOPath is capable of building (and booting) NetBSD and FreeBSD. This compiler should also build most major GNU programs, including Qt and KDE4 (possible bugs in KDE right now though) and all other important software components. The Linux kernel can even be built with this high-performance compiler after applying a trivial patch. PathScale makes a best effort to support all software.
