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