-## ZAFL
- ZAFL is a static rewriting platform for fast, space-efficient, and inlined
- binary fuzzing instrumentation. It currently supports x86-64 C and C++,
- stripped and unstripped, and PIE and non-PIE binaries of all sizes and complexity.
- Beyond conventional instrumentation, ZAFL's API enables transformation passes
- for more effective/efficient fuzzing. Some built-in transformations include
- laf-Intel-style constraint unrolling, Angora-style context sensitivity, and
- InsTrim-style CFG optimizations.

- ZAFL's baseline instrumentation speed averages about 90-95% that of afl-clang-fast's
- conventional LLVM instrumentation (but is even faster when enabling CFG optimizations).
