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