Disassembler Benchmarks

Building

All included code is cross platform compatible, currently benchmarks assume x64.
Build scripts for Visual Studio are included until I get around to cmake

Windows

From a Visual Studio Command Prompt with git in your %PATH%:

git clone https://github.com/moflow/disassembler-benchmarks.git
cd disassembler-benchmarks\src && build.bat

Note this will check out src and attempt to build all decoder libraries and benchmarks.
This currently takes about 7 mins and takes 350 MB for the build trees.

Benchmarks

Current benchmarks supported

• decode to struct
• decode to ascii instruction string
• print address and instruction to null device
• decoder accuracy

The current input is 1 MB taken from the kernelbase.dll .text section generated via:
dd if=/mnt/c/Windows/System32/KernelBase.dll of=kernelbase.text bs=1 skip=0x400 count=$((1024*1024))
