svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm

* Checkout Clang:
cd where-you-want-llvm-to-live
cd llvm/tools
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang

* build

cd where you want to build llvm
mkdir build
cd build
cmake <path to llvm sources>
make -j12

1. copy DOPModule in Custom folder into LLVM_PATH/lib

2. add folder DOPModule into the CMakeLists.txt in LLVM_PATH/lib

   add_subdirectory(DOPModule)

3. run cmake;make in your build folder

Usage:

/path/to/opt -load /path/to/LLVMDOPModule.so -dop-module /path/to/LLVM_IR_FILE 

optional arguments:

-dyn-dop <file>:
    dynamic assist takes in a file of lines containing
    <function name> <line no>
    it will check if line number in the function is contained within a loop,
    if yes, it will search for gadgets within it.

-function-list <file>:
    takes in a path to the file containing functions to track

-details 
    will print the detailed information about the gadgets
