Deflat.py removal tool installed and used to control the flow planarization

Just for the record, it seems to have expired. . . . . . too difficult

Installation Accessories

First of all you want to install virtualenvand virtualenvwrapper:

#安装virtualenv
pip install virtualenv

#安装virtualenvwrapper
pip install virtualenvwrapper

After installation, configure the environment variables
```
export WORKON_HOME=$HOME/Python-workhome
```
Which $HOME/Python-workhomeis next going to store the address of the virtual environment

Startup script

source /usr/local/bin/virtualenvwrapper.sh

virtualenvwrapper related operations command
```
# 创建环境
mkvirtualenv NewEnvName

# 显示当前已有环境
workon

# 切换环境
workon EnvName

# 退出环境
deactivate

# 删除环境
rmvirtualenv EnvName
```
For example (FIG mac is mounted on a presentation, but not installed on angr life and death, to get a long time, and finally changed mounted in ubuntu16.04) :)
Here, we use the command to create a virtual environment called angrenv to complete the remaining operations
```
mkvirtualenv deflatEnv
```

On macOS installation, an error would be crazy, what is the main unicornproblem, toss a long time, and finally moved to Ubuntu, once the installation was successful. . . . . .

From BARF on github repository , find the installation guide, use the following command to install

mkdir barf
cd ./barf
git clone https://github.com/programa-stic/barf-project
cd ./barf-project
sudo python setup.py install

README.md mentioned, you need to install Z3 and CVC4, but did not install the BARF also successfully finished installation. . Besides there is a problem

Using the following command to install deflat

mkdir deflat
cd ./deflat
git clone https://github.com/SnowGirls/deflat.git
cd ./deflat

The github deflat of content may be performed to control the flow flattening removal work using the following command
```
python deflat.py check_passwd_flat 0x400530
```
Which 0x400530is the address of the correlation function IDA
However, I will perform it will complain, look again, according to the control flow flattening tool deflat.py repair remove description, has been modified
Executed again, or error, then see the contents of the issue, it should be a problem because the versions do not match the lead, and the last afternoon to no avail. . . (Used to do the reverse, found not find the main function, casually looking, to see the control flow flattening, the Internet is the same kind of solution - use deflat, first toss on mac, toss on ubuntu, last no fruit in the afternoon, I too hard)
