Let's Learn x86-64 Assembly! Part 3 - Arithmetic and Logic
4.6 parsecs away

Travel
| | [AI summary] The text provides an in-depth exploration of various x86-64 instruction set architectures, focusing on arithmetic operations (ADD, SUB, MUL, SMUL, DIV, SDIV), logical operations (AND, OR, XOR, NOT), and control flow instructions. It details the implementation of these instructions in the QBX virtual machine, emphasizing how they emulate real x86-64 instructions while managing the flags register and handling different operand sizes (8-bit and 16-bit). The text also discusses the nuances of flag handling, register operations, and macro-based code generation to streamline instruction implementation.

Assembly's Perspective of C - Stephen Marz
24.4 parsecs away

Travel
| [AI summary] The text provides an in-depth explanation of how C programs are compiled into assembly and machine code, focusing on various aspects such as data types, memory sections, control structures, and the role of the compiler in making decisions about load/store operations and shifts. It covers topics like data type conversions, padding in structures, global variables, and branch instructions for conditions and loops. The text also mentions the importance of understanding assembly for learning how compilers work and the use of tools like objdump for analyzing compiled code.
