The C++ team is committed to making your C++ coding experience as safe as possible. In the last couple of releases, we added new safety checks based on the requests of internal customers like the Windows group. Below is the overview of the new checks. For additional information for each of the checks, please refer to the linked help documents. C6395: Helping migration to C++17 and above Consider the following snippet: a[++i] = i; The meaning of the code depends on the order in which we evaluate the subexpressions. In case we evaluate the left-hand side of the assignment first, the code store ..read more

Our previous blog post about OpenMP support in Visual Studio announced support for the loop collapse feature in version 17.8.  In the meantime, we have continued working on improving the feature and, in Visual Studio 2022 17.10, we have added a new, more efficient algorithm for partitioning work of certain types of collapsed triangular loops supported by the OpenMP Standard 5.2. All this work continues to be accessible if you are using the -openmp:llvm switch (see the Improved OpenMP Support for C++ in Visual Studio blogpost for details about this switch). In this blog we will describe th ..read more
