GCC 9.1 Released Version 9.1 of the GCC compiler suite is out. " In this release C++17 support is no longer marked experimental. The
C++ front-end implements the full C++17 language (already previous GCC
major version implemented that) and the C++ standard library support is
almost complete. The C++ front-end and library also have numerous further
C++2a draft features. GCC has a new front-end for the D language.
GCC 9.1 has newly partial OpenMP 5.0 support and almost
complete OpenACC 2.5 support." See this page for an extensive list of changes. | | 2:40p |

dav1d 0.3.0 released The Alliance for Open Media developed the AV1 patent-free video codec and sponsors the development of dav1d, a reference optimized decoder for AV1. The 0.3.0
release of dav1d is now available. " This third release continues to increase the ARM and SSSE3 speed, with more optimizations, as announced, and we get between 12 and 25% speed increases on those CPUs, depending on the samples.
However, more surprisingly, we got a speedup on AVX-2 CPU, by optimizing the MSAC (entropy decoding), while we did not find a good solution in the past. This brings 4-5% speed improvements, which is quite huge, knowing the maturity of the AVX-2 code." |
