Steps to compile and run the code : 1. Make sure that llvm-config is visible in your path. Type ' which llvm-config' and check that you get the path to your llvm config. The version I have tested this code for is llvm-3.6.1. 2. Type 'make' and the executable 'reg_pressure' should be generated. 3. Type ' ./reg_pressure ./sample/example.ll ' to obtain reg pressure for some example LLVM IR file.
