Static vs Dynamic Typing Why Static Type Systems Are Safer, and Why Dynamic Languages Are Adopting Them
Static vs Dynamic Typing: Why Static Type Systems Are Safer, and Why Dynamic Languages Are Adopting Them Programming languages can be broadly classified into two categories based on their type systems: statically typed and dynamically typed. This classification refers to when the language checks the types of variables…

Practical Examples and Debugging Testing with Disassemblers and objdump
Practical Examples and Debugging: Testing with Disassemblers and objdumpTesting is a critical phase in assembler development. Verifying that the output machine code matches the intended instructions ensures correctness and robustness. One of the most effective approaches for validating assembled output is using…

Architecture of an Assembler Data Structures in Assembler Design - Instruction Table
Architecture of an Assembler: Data Structures in Assembler Design -> Instruction TableThe instruction table is the core reference structure that an assembler uses to map mnemonic representations of machine instructions to their corresponding binary encodings, operand patterns, and encoding rules. It acts as the bridge…

Architecture of an Assembler Code generation converting tokens to binary
Architecture of an Assembler: Code generation: converting tokens to binaryThe code generation phase is the assembler’s core responsibility—translating the parsed instructions and directives into raw machine code. This involves converting high-level symbolic tokens into binary encodings that conform precisely to the…

Architecture of an Assembler Symbol resolution and backpatching
Architecture of an Assembler: Symbol resolution and backpatchingAfter code generation has constructed the initial binary stream, an assembler must resolve all symbolic references to their actual numeric addresses or offsets. This is the symbol resolution phase, which ensures correctness of jumps, calls, data accesses,…

RISC-V The Open Architecture Revolution for Low-Level Developers
RISC-V: The Open Architecture Revolution for Low-Level Developers1. Introduction to RISC-VRISC-V (pronounced "risk-five") is a free, open, and extensible instruction set architecture (ISA) based on reduced instruction set computing (RISC) principles. It was created at the University of California, Berkeley, in 2010…

Understanding Executable File Headers Across Platforms (Windows, Linux, macOS) — With Hex Analysis
Understanding Executable File Headers Across Platforms (Windows, Linux, macOS) — With Hex AnalysisWhen a program is compiled into an executable, it carries a binary header at the beginning. This header is crucial — it tells the operating system how to load and run the program. These headers differ across platforms and…

Apple Silicon M4 processor ARMv9.2-A architecture
Apple Silicon M4 processor ARMv9.2-A architecture General-Purpose Registers (GPRs)The ARMv9.2-A architecture, which the Apple M4 adheres to, defines 31 general-purpose 64-bit registers, named X0 through X30. Each can also be accessed as 32-bit W0–W30. Register X31 serves as the zero register (when used as a source) or…
