cctools 65 — Quick Reference & Usage Guide

• ld (Linker): The "Link Editor." It takes object files (.o) and combines them into a final executable. The cctools ld is distinct from the GNU ld because it understands Mach-O specifics.
• as (Assembler): Assembles assembly code into machine code for ARM (arm64, armv7) and x86 architectures.
• otool: The "Object Tool." This is the standard utility for displaying specified parts of object files or libraries (similar to readelf on Linux or dumpbin on Windows).
• nm: Lists symbol table entries (function names, variables) from object files.
• lipo: Used to create, view, or manipulate "Universal Binaries" (fat binaries that contain code for multiple architectures, like arm64 and x86_64 in one file).
• codesign_allocate: A helper tool used to allocate space for code signatures within a binary.
