JitBox

Ultra lightweight header-only jit with no external dependencies.

Example:

Given this simple c function as an example:

   int square (int i)
   {
     return i * i;
   }

This is how you might generate this function in jitbox:

    jitbox::Module module = jitbox::Module("square_test");

    jitbox::ValueType return_type = jitbox::ValueType::i32;
    jitbox::Function* func = module.new_function("square", return_type);
    jitbox::Value* x = func->new_param("x", jitbox::ValueType::i32);

    func->begin_block("entry");
    func->end_block_with_return(func->mul(x, x));

    module.compile();

    typedef int (*square_proto)(int);
    square_proto square = (square_proto)func->get();

    cout << "5 * 5 = "   << square(5) << endl;
    cout << "3 * 3 = "   << square(3) << endl;
    cout << "9 * 9 = "   << square(9) << endl;
    cout << "16 * 16 = " << square(16) << endl;

Build and run examples:

g++ -std=c++11 examples/helloworld.cpp -Ijitbox/ -o hello
./hello
g++ -std=c++11 examples/square.cpp -Ijitbox/ -o square
./square
