Daedalus is an LLVM Pass that maps Instructions to Program Slices. Our end goal is to use program slices as a unit of program compression, by outlining common slices; hence, making code shorter.

The preferred way to build Daedalus is as an out-of-tree LLVM pass. You can do the following to compile and install it as a library:

mkdir build
cd build
cmake -DLLVM_DIR={path_to_llvm_project} ../
make
cd ..
opt -load-pass-plugin build/lib/libdaedalus.so -passes=daedalus -disable-output tests/test1.ll

After building Daedalus, you can extract program slices using a script we have: comp.sh. This script will compile a C program and invoke Daedalus on it:

chmod +x comp.sh
./comp.sh {path_to_test_file}
# ex
./comp.sh tests/test1.ll

If, otherwise, you prefer to load and run the pass directly, you can simply do:

cd build
make
cd ..
opt -load-pass-plugin build/lib/libdaedalus.so -passes=daedalus -disable-output {path_to_test_file}

But, in this last case, remember that you must apply Daedalus onto a program written in the LLVM IR.
