| | | | | [AI summary] The article discusses the process of learning to read x86 assembly language, focusing on how it can be a useful skill for understanding low-level operations of microprocessors. It outlines the challenges of reading assembly, especially in debugging scenarios, and provides an example of translating Ruby code into x86 assembly using Crystal. The article also explains the syntax and structure of x86 assembly, including register usage, instruction suffixes, and the differences between AT&T and Intel syntax. It highlights the complexity of x86 assembly due to its historical evolution and the need for understanding register sizes and operand notation. | |

| | | | | [AI summary] The provided text is a detailed explanation of how to write a simple 64-bit Windows application in assembly language that calls the ExitProcess function from the KERNEL32.DLL library. It covers the following key topics: 1. **Memory and Register Basics**: Explains how memory and registers work in 64-bit Windows, including the use of the stack pointer (RSP), registers like RCX, RDX, R8, and R9 for passing arguments, and the importance of stack alignment for performance. 2. **Calling Conventions**: Details the 64-bit Windows calling convention, including how the first four integer or pointer arguments are passed in registers (RCX, RDX, R8, R9), how additional arguments are passed on the stack, and the requirement for the stack to be aligned to ... | |
