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

To analyze assembly output using Clang, you can use the -S option to generate assembly code and the -fverbose-asm option to include additional comments in the assembly output. This can be particularly useful for understanding how your high-level C++ code translates into assembly instructions. Here's a step-by-step guide on how to do this:

In the example above, `example.cpp` is your C++ source file, and `example.s` is the resulting assembly file. The `-fverbose-asm` flag adds comments to the assembly output, providing insights into the corresponding C++ code.

You can then open the `example.s` file in a text editor to analyze the generated assembly instructions and understand the optimizations performed by the compiler.
