3.1.4.6 Compiling the context ¶

Having finished looping over the blocks and populating them with statements, the context is complete.

We can now compile it, extract machine code from the result, and run it:

class compilation_result
{
public:
  compilation_result (gcc_jit_result *result) :
    m_result (result)
  {
  }
  ~compilation_result ()
  {
    gcc_jit_result_release (m_result);
  }

  void *get_code (const char *funcname)
  {
    return gcc_jit_result_get_code (m_result, funcname);
  }

private:
  gcc_jit_result *m_result;
};

  compilation_result compiler_result = fn->compile ();

  const char *funcname = fn->get_function_name ();
  toyvm_compiled_func code
    = (toyvm_compiled_func)compiler_result.get_code (funcname);

  printf ("compiler result: %d\n",
	  code (atoi (argv[2])));
