The May 2020 update of the Visual Studio Code C++ extension is now available. This latest release offers brand new features—ARM and ARM64 IntelliSense modes and C++ language-specific code folding—along with a bunch of enhancements and bug fixes. To find out more about all the changes, check out our release notes on GitHub.

ARM and ARM64 IntelliSense modes

With the May 2020 update, you can configure the C++ extension to provide proper IntelliSense when cross-compiling for ARM and ARM64. This means you’re compiling for a different architecture than your host development machine. All you need to do is set your compiler path and IntelliSense mode.

Your compiler path and IntelliSense mode configuration are stored in your project’s c_cpp_properties.json file. Edit these settings by selecting C/C++: Edit Configurations (UI) from the Command Palette.

Under Compiler path, enter the path to the compiler compatible with your target architecture. For example, “/usr/bin/arm-none-eabi-g++” if compiling for ARM from a Linux machine.

Then set IntelliSense mode to the architecture-specific variant of the compiler you are using. The May 2020 update provides the following new IntelliSense modes: clang-arm, clang-arm64, gcc-arm, gcc-arm64, msvc-arm, and msvc-arm64. For example, select “gcc-arm” if you’re using GCC to compile for ARM.

Now you’re all set to enjoy IntelliSense while cross-compiling for ARM! To learn more, see Configure IntelliSense for cross-compiling.

Code folding

The May 2020 update provides C++ language-specific code folding, enabling you to easily collapse and expand blocks of code. The code folding provided by the C++ extension addresses the buggy behavior of the previous non-language-specific code folding experience. Specifically, code folding now works as expected for #if statements, #include statements, and block comments.
