Managed Code vs Unmanaged Code: A Deep Dive into Performance, Control, and Safety
In the ever-evolving world of software engineering, developers frequently face trade-offs between control and convenience, performance and safety, raw...
Practical Examples and Debugging: Testing with Disassemblers and objdump
Testing is a critical phase in assembler development. Verifying that the output machine code matches the intended instructions ensures correctness and...
Practical Examples and Debugging: Encoding Debugger: Step Through Assembly → Machine Code
An essential tool for developing and debugging an x86-64 assembler is an encoding debugger—a specialized utility that enables the developer to step ...
Quantum Processors: A Fundamental Difference from Classical Architectures (x86, ARM, RISC-V)
Since the invention of computers, classical processors (like x86, ARM, and RISC-V) have gradually evolved to become smaller, faster, and more efficien...
Practical Examples and Debugging: Building Step-by-Step with Makefiles.
When developing an x86-64 assembler in C/C++, managing the build process effectively is essential to streamline compilation, facilitate incremental bu...
Practical Examples and Debugging : Writing a Full Sample Assembler in C/C++
Designing and implementing a full assembler in C or C++ is an excellent practical exercise to consolidate the understanding of assembler architecture,...
Assembler Internals: Design Decisions -> Custom Directives and Instruction Macros
1. Introduction Custom directives and instruction macros are powerful features within assembler design that enhance expressiveness, flexibility, and...
Assembler Internals: Design Decisions -> Label Resolution and PC-Relative Addressing
1. Overview Label resolution and PC-relative addressing are critical components in the design of an x86-64 assembler, deeply affecting code generati...
Assembler Internals: Design Decisions -> Symbol Resolution Strategies
1. Introduction Symbol resolution is a fundamental process within an assembler responsible for mapping symbolic names—such as labels, variables, a...
Assembler Internals: Design Decisions -> Macro Processors and Performance Tradeoffs
1. Introduction Macro processing is a powerful feature in assemblers that allows programmers to define reusable code templates or macros, which can ...
Assembler Internals: Design Decisions -> One-pass vs Two-pass Assemblers
1. Introduction A fundamental design decision when creating an assembler is choosing between a one-pass or two-pass architecture. This choice signif...
Object File Generation : Creating Relocatable Object Files -> Using Libraries (e.g., libelf, LLD) to Assist
Introduction Developing a complete assembler capable of producing valid relocatable object files compliant with ELF specifications involves signific...
