compiler

0. For environment, you need clang. For development, you need LLVM libraries. Compile the LLVM_IR_to_XML tool first

$ clang++ output.cpp -o output `llvm-config --cxxflags --libs --ldflags --system-libs` 

The tool is already compiled for x86-linux environment

1. To compile, you need the llvm ir bitcode file. Then use the LLVM_IR_to_XML tool to convert llvm ir bitcode file to xml file. You can use helper.py in test/ to do this

$ test/helper.py test/test_code_your_code/your.c

2. set the xml file in main.py

backend = Backend("test/test_code_your_code/your.xml")

3. Run python main.py

$ python main.py > test/test_code_your_code/your.subneg4

4. Run assembler

$ sim/assembler.py test/test_code_your_code/your.subneg4

5. Run simulator

$ sim/simulator.py test/test_code_your_code/your.subneg4.mem

OR you can use the JavaScript tool for assembler and simulator in x/ folder

Notes

1. Still in progress, so not much instructions are supported
