The Contemporary Dominance of AArch64
Parent section: Architectural Set Selection: The Prerequisite Choice for Assembly
AArch64, ARM’s 64-bit architecture, represents a pragmatic middle ground2. It powers nearly the entire global mobile ecosystem, modern Apple Silicon, and an increasing share of energy-efficient cloud infrastructure (such as AWS Graviton instances)2.
AArch64 implements a modern, streamlined RISC load-store architecture with 31 general-purpose 64-bit registers and fixed 32-bit instruction widths, avoiding the accumulated design debt of x86-64 while providing native execution on modern ARM workstations2.
For a developer operating on modern Apple hardware, AArch64 provides the smoothest path to native, bare-metal assembly experimentation2.

| ID | Severity | Evidence | Status | Location | Problem |
|---|---|---|---|---|---|
| D01-m4 | minor | KNOW | open | L126 | AArch64 on Apple = “bare-metal” experimentation. User space on macOS is not bare metal. Also, the Apple syscall interface is not a stable public ABI. |
