In the Summer of 2013, Facebook engineers started a major redesign of the HHVM JIT compiler that brought an overall 15% reduction of CPU usage on Facebook’s web servers. Facebook engineer Guilherme Ottoni has recently described how Facebook achieved that result by backing profile-guided optimizations (PGO) into their JIT compiler.
Microsoft continues to refine their new extension for Visual Studio 2015 which provides developers with the ability to write C/C++ code in VS2015 and then transfer it to a remote machine running Linux for compilation and debugging. This combines the benefits of Visual Studio's IDE with advantages of a Linux deployment environment.
Go 1.7 significantly improves both compile times and runtime performance, says Google engineer Chris Broadfoot. It also adds hierarchical tests and benchmarks and official support for Linux on IBM z Systems (s390x).
Newly released Rust 1.10 introduces a new approach to bootstrapping that aims to be friendlier to open-source distributions. Additionally, it adds a new cargo option for handling panic that improves compiler performance and reduces binary size, a new format for shared libraries, and many performance improvements.
The full release of Visual Studio 2015 Update 3 has been made. Update 3 places a great emphasis on improving the stability of the product and reducing the amount of memory used by the IDE for solutions of all sizes. Other changes include better C++ support and better handling of product activation.
Microsoft has open sourced Checked C, a research project meant to add bounds checking to C and C++.
Visual Studio 2015 users have a new way to write C++ code for non-Windows environments. Thanks to the Visual C++ for Linux extension, VS2015 supports writing C++ code under Windows and then deploying that code to a Linux machine for compilation, execution, and debugging. New features increase the usefulness by adding a Linux Console Window and fixing several bugs.
Microsoft's code-based multiplatform editor Visual Studio Code has sought to be a go-to choice for developers whether they use Windows, Mac OS X, or Linux. One aspect that has limited the editor is the lack of proper C/C++ support beyond basic syntax highlighting. A new Microsoft extension seeks to narrow the feature gap while providing several C/C++ focused tools.
The main reference in compiler construction, Compiler: Principles, Techniques, and Tools, also know as the Dragon Book, was first published in 1986. Anders Hejlsberg, known for his work on Turbo Pascal, Delphi, C# and TypeScript, explains in a Channel 9 interview how compiler construction today is different from how it was done 30 years ago.
Five months after the introduction of version 1.60, Boost hits version 1.61, adding several new libraries and updating many more.
Version 6.1 is the first major GCC release in about one year. It contains substantial new functionality, says GCC maintainer Jakub Jelinek, including new C++17 features, full support for OpenMP, and improved support for OpenACC.
When Go 1.7 development cycle has still about a couple of weeks to go, Go committer Dave Cheney has reported on the team efforts to improve the toolchain for the coming release.
Microsoft has announced the first preview of Visual Studio 2015's successor. Even more impressive is a new extension available now that provides VS2015 with the ability to create and develop C++ projects for Linux and UNIX based systems.
Android N introduces a hybrid runtime using compilation + interpretation + JIT to obtain the best compromise between installation time, memory footprint, battery consumption and performance.
