In Visual Studio 2022 17.14, we are introducing the switch, which generates and links with out-of-line atomics that select Armv8.1+ Large System Extension (LSE) atomic instructions based on CPU support. This switch is on by default for Armv8.0 and off for Armv8.1+. Outlining is necessary in Armv8.0 because this version's interlocked intrinsics ...

Visual Studio 2022 17.11 brings new optimizations, intrinsics, features, and improvements to the MSVC backend. Check out the highlights below:  ...

Visual Studio 2022 17.10 brings new optimizations, intrinsics, features, and improvements to the MSVC backend. Check out the highlights below: Do you want to exp...

In Visual Studio 2022 17.10 Preview 2, we’re including a small quality-of-life improvement that results in the Watch/Locals window displaying local variables correctly for any arbitrary frames in the call stack in debug builds. To try it out, please install the recently released Preview. For more information, read on.  The problem: missing varia...

Since Visual Studio 2022 version 17.3, we have continued to improve the C++ backend with new features, improved support for arm64 and OpenMP, and new and improved optimizations across all architectures.

This post provides a behind-the-scenes look at how we test MSVC's backend, which is responsible for optimization and code generation. Many people worldwide use our compiler and expect it to provide a high-quality experience in terms of correctness (compiled code behaves as written), performance (speed of the compiled code), and throughput (speed...

Visual Studio 2022 17.8 has been released recently (download it here). While there is already a blog “Visual Studio 17.8 now available!” covering new features and improvements, we would like to share more information with you about what is new for the MSVC ARM64 backend in this blog. In the last couple of months, we have been improving code-generat...

In Visual Studio 2022 version 17.6 we added a host of new ARM64 optimizations. In this 2nd edition of our blog, we will highlight some of the performance improvements to MSVC ARM64 compiler backend, we will discuss key optimizations in the Visual Studio 2022 version 17.7 for both scalar ISA and SIMD ISA (NEON). We started introducing these performa...

In the last couple of months, the Microsoft C++ team has been working on improving MSVC ARM64 backend performance and we are excited to have a couple of optimizations available in the Visual Studio 2022 version 17.6. These optimizations improved code-generation for both scalar ISA and SIMD ISA (NEON). Let’s review some interesting optimizations in ...

This blog post presents some of the optimizations the backend team has implemented for Visual Studio 2022.
