We know that setting up tasks.json and launch.json to run and debug C++ files isn’t always fun. Number of hardware supported data breakpoints The table below shows how many registers are available to use per architecture. This limitation comes from the fact that the architecture that your program runs on has a limited number of hardware data breakpoints it can use. This is because the string type is 32 bytes, and there’s a limitation on the size we can set data breakpoints on. In this same example program, if you set a data breakpoint on msg of type string, you might see an error message in the Debug Console that says: Unable to set data breakpoint: Value does not fall within the expected range.
Sure enough, execution breaks when i changes value from 1 to 2. Use the debug control panel to continue running the program. In this example, if we continue running the program, the next time it breaks will be when local variable i changes value. Immediately, you’ll see the data breakpoint listed in the Breakpoints section of the debug pane. To set a data breakpoint while debugging in VS Code, right click on a variable in the debug pane and select Break on Value Change. Data breakpoints break execution when a value stored at a specified memory address changes. In case you missed it, version 1.8.4 of the C++ extension brought support for data breakpoints (#1410) while debugging C++ programs with GDB in VS Code. Give it a try and let us know what you think! If you run into any issues, please follow up on the GitHub tracking issue (#7035). With this latest release of the C++ extension, you can seamlessly debug C++ programs when running VS Code on the M1 chip. At the time, the C++ extension’s debugger binaries did not run natively on the M1 chip. Last year, we enabled language server support for Apple Silicon ARM64 architecture, which meant you could run the C++ extension’s language server (responsible for things like IntelliSense, code navigation, and autocomplete) natively on the Apple M1 chip. It’s been a minute since our last blog post about C++ in VS Code, but we’ve been working hard on new features and bug fixes! Today, we’re excited to fill you in on the latest and greatest C++ debugger improvements in VS Code, including support for the Apple M1 chip, data breakpoints, and a new run/debug play button!
