Disassembly View<\/h2>\n

We\u2019re excited to announce that Disassembly View\u2014 our #1 upvoted GitHub issue (#206<\/a>)\u2014 is publicly available in VS Code Insiders! Disassembly View allows you to debug assembly code corresponding to the instructions created by your compiler. It\u2019ll be available in the 1.59 release of Visual Studio Code in August, but in the meantime you can download VS Code Insiders<\/a> and try it out!<\/p>\n

To open Disassembly View while debugging, right click your source code and select Open Disassembly View. <\/strong><\/p>\n

\"Image<\/a><\/p>\n

In the Disassembly View, the yellow hollow marker represents the current instruction. For each instruction, you\u2019ll see the memory address (left column) and the machine language instructions displayed as hex (middle column) and as assembly language (right column). You can navigate between instructions, step over (F10<\/strong>) and step in to (F11<\/strong>) instructions.<\/p>\n

\"Image<\/a><\/p>\n

To set a breakpoint in the Disassembly View, hover over the instruction and click the red filled circle that appears to the left of the memory address.<\/p>\n

\"Image<\/a><\/p>\n

Unset the breakpoint by clicking the red dot again, or by unchecking the box in the Breakpoints section of the Debug pane.<\/p>\n

Macro Expansion<\/h2>\n

With this latest release of the C++ extension, you can expand macros inline (GitHub issue #4183<\/a>), making it easier to read and understand your code. To expand a macro inline, click on it, select the lightbulb, and then click Inline macro.<\/strong><\/p>\n

Windows ARM64 Debugging<\/h2>\n

Last year, we announced support for running the C++ extension on Windows ARM64 architecture, giving Surface Pro X users access to C++ IntelliSense, code navigation, and build support. With the July 2021 update of the C++ extension, you can debug projects on Windows ARM64, completing the end-to-end Surface Pro X C++ development experience in VS Code.<\/p>\n

What do you\u202fthink?<\/h2>\n

Download the C++ extension for Visual Studio Code<\/a>\u202ftoday, give it a try, and let us know what you think. If you run into any issues, or have any suggestions, please report them in the\u202fIssues section of our GitHub repository<\/a>. You can also join our Insiders program and get access to early builds of our release by going to\u202fFile<\/strong>\u202f>\u202fPreferences<\/strong>\u202f>\u202fSettings<\/strong>\u202fand under\u202fExtensions<\/strong>\u202f>\u202fC\/C++,<\/strong>\u202fchange the \u201cC_Cpp: Update Channel<\/strong>\u201d to \u201cInsiders<\/strong>.\u201d Then under\u202fFeatures\u202f<\/strong>>\u202fExtensions<\/strong>, enable \u201cExtensions<\/strong>:\u202fAuto Update<\/strong>.\u201d<\/p>\n
