The article details an experiment in minimizing the size of Zig-compiled ELF binaries, starting from a 2180KB 'do nothing' program and reducing it to just 12KB through various optimization techniques like stripping debug info and using ReleaseSmall mode. While significant reductions were achieved, the binary remains far from the theoretical 80-byte minimum for ELF executables, highlighting the inherent overhead in Zig's runtime and standard library. The technical walkthrough provides valuable insights for developers working on size-constrained embedded systems or CTF challenges.
Background
Zig is a general-purpose programming language designed for robustness, optimality, and clarity, with a focus on systems programming. ELF (Executable and Linkable Format) is a common standard file format for executables, object code, and shared libraries on Unix-like operating systems.
