I have used Intel C++ compiler (Intel® oneAPI DPC++/C++ Compiler to be precise) for computationally intensive applications and I have found its performance to be top-notch. As you proceed through this blog post you will understand why a lot of other C++ compilers want to base their code on this open-source platform. The current version of Clang/LLVM, version 12.0, currently supports C++17 fully and has experimental support for C++20. I had detailed the architecture of this compiler and described how the LLVM backend makes it easy to add new optimizations to the compiler. In one of my recent blog posts, I had compared GCC vs Clang. Notably, GCC 11 also includes some features of the draft C++23 standard which is the next revision of the C++ standard after C++20. It also has experimental support for almost all of the C++20 language and library features, except for some minor features in Modules. The current version of GCC, GCC 11, has full support for C++17 core language features as well as C++17 library features. It is a tool that can be used to compile multiple languages and not just C or C++. The GNU compiler collection, GCC, is one of the most famous open-source tools in existence. Checkout this nice video to learn more on this topic. Although the Visual C++ compiler is primarily used for Windows development, using the windows subsystem for Linux (WSL) integration, it can be used to develop native Linux applications too.
It is expected that Visual Studio 2022 – which is currently in the preview version – will include a Visual C++ compiler that will fully support the C++20 features. The current compiler version, bundled with Visual Studio 2019 version 16.10, is 4, which supports both the C++17 core language features as well as C++17 library features completely and the C++20 features partially.
This is the C and C++ compiler that Microsoft bundles with Visual Studio. Top C++ compilers for hosted environments One day, I shall write a blog on development under freestanding environments for C++, but this blog is about the compilers I consider to be top-notch in their game. There are many requirements to run under such an environment which you can check out here. Lack of an Operating System makes a freestanding environment very restricted.
When a C++ program executes without the help of an Operating System, it is running under a freestanding environment. Normally, we compile and run C++ code for a platform (or a host) which is known as the hosted environment. In the same way, there are many C++ IDEs, but I discuss that in a different blog post. So naturally, there are a lot of C++ compilers out there. One of the things I love about C++ is the fact it’s such an ‘open’ programming language that allows anyone to implement their own compiler.
