1. get a copy of our modified llvm from here and build it
2. modify Makefile to set CONFIG to /path-to-custom-built-llvm/bin/llvm-config
3. do make

If you don't want to build LLVM, you can checkout executables from this repo as well (ug, create-server, add.bc, mul.bc, id.bc). WARNING: These executables were only tested on OS X Yosemite.

1. compile testcase to llvm bitcode file. For example, you can do this

clang -c -emit-llvm add.c -o testcase

2. run the superoptimizer like this

# in this case `add` is name of the function you would like to optimize
./ug -fadd testcase.bc
