It's Been Five Years Since The Open64 5.0 Compiler Release

This week marked five years since the release of the Open64 5.0 compiler in what is the latest and likely last-ever release of this once-promising code compiler.

Open64 5.0 was released back in 2011 and unfortunately there hasn't been a release since. Last year we wrote how the Open64 project vanished. A few days after that article, it was said back on 27 March 2015, "The websites and SVN servers are down for maintenance and will be back soon."

A year and a half later, hasn't returned and the project still seems to be discontinued/abandoned without any official communication. Their mailing list also remains a virtual ghost town.

AMD's Open64 compiler suite they previously maintained for AMD CPUs also hasn't seen a release since 2013 and appears abandoned as well.

Somewhat related, the Portable C Compiler (PCC) has also been virtually silent. There has been some relatively recent developments at least as of the beginning of 2016 and in 2015 they enabled C11 support by default, but no release since 2014. Their FishEye source code development viewer to show any new development activity has also been offline for an unknown amount of time while the official project site remains quite bare.

At least GCC and LLVM/Clang continue providing competition to one another and keep advancing in-step as open-source, well-supported compilers. Promising commercial but closed compiler efforts remain from the likes of Intel and PathScale.
