Assembly & Related Notes

These notes are focused on assembly language and related tooling (linkers, loaders, etc).

Speficially, those used on the following machines:

• Modern personal computers (MS Windows, Linux, or Mac)
• Video Game Consoles (fourth gen and up)

Tools

Order by interest. My preference was on simple tools written in a C-like, data-oriented, or procedural way. I don't want to deal with low level tooling marred by dense language abstractions.

Zydis

• ZASM (Zydis frontend, not to be confused with Z80 assembler...)

YASM (Rewrite (on some) of Netwide in C)

• Design
• User Manual
• libyasm

DynASM

AssemblyLine

AsmJit

• AsmTK

VASM

FASM

TASM

HLA

Assemblers below are just noted to exist but I don't care for.

xbyak

Keystone assembler framework

MASM

Netwide Assembler

GAS

Exectuable Formats

• PE Format
• ELF
• Mach-O
