Before we start, I want to make sure you understand that the code we write is quite unsafe and is not a “best practice” when writing Rust. I want to
Note The actual addresses you get will be different every time you run the program. In other words, the values 240, 205, 252, 56, 67, 86, 0, 0 represent the
Tip As we end the program in an endless loop, you’ll have to exit by pressing Ctrl + C. OK, so what happened? We didn’t call the function hello at
Options The last thing we need to introduce to get a minimal understanding of Rust’s inline assembly for now is the options keyword. After the input and output parameters, you’ll
Now, this is where it gets a little difficult. On the x86-64 instruction set, there is no way for us to manipulate rip directly, so we have to use a
As mentioned earlier, this architecture of the CPU features a set of 16 general-purpose 64-bit registers, 16 SSE registers with 128-bit width, and 8 floating point registers with 80-bit width:
To find the architecture on your current system, run one of the following commands in your terminal: On Linux and MacOS: arch or uname -m On Windows PowerShell: $env:PROCESSOR_ARCHITECTURE On
