How do I analyze assembly output (-S, -fverbose-asm) with MSVC?

To analyze assembly output using MSVC, you can use the /FAs option along with the /FAs flag to produce assembly code with a verbose output. This will help you understand how your C++ code is translated into assembly language. The generated assembly files can provide insights into optimizations and performance characteristics of your functions.

Here is an example of how to compile a simple C++ program to generate assembly output:

// To analyze assembly output using MSVC, follow these steps: // 1. Open your Visual Studio project. // 2. Open the project properties: Right-click on your project in Solution Explorer, then select "Properties". // 3. Select C/C++ -> Output Files from the left panel. // 4. Set "Assembler Output" to "Assembly With Source Code (/FAs)". // 5. Save your changes and build the project. // 6. Check the output directory for the generated .asm file.
