Binutils

Covers the bread and butter of binary post-processing: creating static libraries with ar, stripping debug info while keeping separate symbol files, converting crash addresses to source lines with addr2line, and demangling C++ symbols. The objcopy examples are especially practical, like embedding binary data as linkable symbols or separating debug info so GDB can find it automatically. You'll reach for this when dealing with release builds, crash logs, or embedded targets where binary size matters. The cross-compilation prefix reminders are a nice touch since that's where these tools really earn their keep. Assumes you already know why you need to strip or demangle something, just shows you the exact incantations.
