AMD & Others No Longer Seems To Enjoy Open64

AMD's Open64 compiler hasn't seen a release in nearly one year while for the upstream Open64 project it's been over two years since the last upstream release.

With all of the AMD Kaveri articles on Phoronix in the past two weeks there's been many requests for different Linux / open-source benchmarks, among which a some been about Open64 compiler testing... While most of the compiler tests we do at Phoronix are with GCC and LLVM/Clang, a few Kaveri requests have come in about Open64. However, there's little upstream activity these days on Open64.

AMD's version of Open64 is available from the AMD developer area but it hasn't seen a release in nearly one year. AMD hasn't put out a release since the initial Piledriver CPU support. Thus there's no new release of AMD Open64 with any optimizations for the Steamroller micro-architecture found on Kaveri APUs nor any other compiler improvements in the past year like improved C/C++ support, new code generation optimizations, etc.

In terms of the upstream Open64 compiler project, it's even more dormant with no release since Open64 5.0 that happened in November of 2011. There's also little upstream mailing list activity (from zero to a handful of mailing list messages per month on the user and developer lists). The last SVN modification to the Open64 code was one month ago and in going through their SVN log there hasn't been any really interesting commits in ages.

So, no, Open64 isn't going to be tested on Kaveri/Steamroller unless there's some magical AMD Open64 release in the near future. In terms of the more interesting GCC and Clang, there were some initial benchmarks I published already while further cross-compiler and optimization testing is forthcoming on Phoronix.
