# 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
