# Simple fuzzing tool by disassembling random code. By Nguyen Anh Quynh, 2014
# Syntax:
# ./suite/fuzz.py --> Fuzz all archs
# ./suite/fuzz.py x86 --> Fuzz all X86 (all 16bit, 32bit, 64bit)
# ./suite/fuzz.py x86-16 --> Fuzz X86-32 arch only
# ./suite/fuzz.py x86-32 --> Fuzz X86-32 arch only
# ./suite/fuzz.py x86-64 --> Fuzz X86-64 arch only
# ./suite/fuzz.py arm --> Fuzz all ARM (arm, thumb)
# ./suite/fuzz.py aarch64 --> Fuzz ARM-64
# ./suite/fuzz.py mips --> Fuzz all Mips (32bit, 64bit)
# ./suite/fuzz.py ppc --> Fuzz PPC
