srciror

SRCIROR (pronounced sorcerer) is a SRC and IR mutatOR. It performs mutations on source code written in C/C++ and on the LLVM IR.

BUILDING:

0. Need dependencies: python python3 clang lib32z1-dev

1. Build LLVM locally (if you do not already have it built). You can execute the provided script:
   ./llvm-build.sh
   This creates llvm/ and llvm-build/ directories.

2. Build the SRC mutator. To build SRC mutator, see SRCMutation/README.

3. Build the IR mutator. To build IR mutator, see IRMutation/README.

4. Build the IR instrumentation code:
   cd IRMutation/InstrumentationLib/; ./build-lib.sh

5. Set up the environment variables needed by SRCIROR.

   export SRCIROR_LLVMMutate_LIB=${PATH_TO_LLVM_BUILD}/Release+Asserts/lib/LLVMMutate.so

   export SRCIROR_SRC_MUTATOR=${PATH_TO_SRCIROR_DIR}/SRCMutation/build/mutator

   export SRCIROR_LLVM_BIN=${PATH_TO_LLVM_BUILD}/Release+Asserts/bin/

   export SRCIROR_LLVM_INCLUDES=${PATH_TO_LLVM_BUILD}/Release+Asserts/lib/clang/3.8.0/include/

   export SRCIROR_COVINSTRUMENTATION_LIB=${PATH_TO_SRCIROR_DIR}/InstrumentationLib/SRCIRORCoverageLib.o

Either set environment variables PATH_TO_LLVM_BUILD and PATH_TO_SRCIROR_DIR, or replace them with the corresponding values in the statements above.
