IL2C - A translator for ECMA-335 CIL/MSIL to C language.

Intermediate language everywhere!

What's this?

  • IL2C is a translator (transpiler) of ECMA-335 CIL/MSIL to C language.

  • We're aiming for:

    • Better predictability of runtime costs
      Better human readability of C source code translated by IL2C.
    • Very tiny footprint requirements
      We're thinking about how to fit from large system with many resources to tiny embedded system. (KB order for the non-OSes system)
    • Better code/runtime portability
      Minimum requirement is only C99 compiler. The runtime minimum requires only the heap, CAS instructions, (POSIX) signal and setjmp/longjmp. Additional better feature is threading API (Win32, pthreads and FreeRTOS.)
    • Better interoperabilities for existed C libraries
      You can use the standard .NET interop technics (like P/Invoke.)
    • Containing seamless building systems for major C toolkits
      for example: CMake system, Arduino IDE, VC++ ...

Simple hello-world like code

Original C# source code:

public static class HelloWorld
{
    public static void Main()
    {
        Console.WriteLine("Hello world with IL2C!");
    }
}

Translated to C source code (all comments are stripped):

IL2C_CONST_STRING(string0__, L"Hello world with IL2C!");

void HelloWorld_Main()
{
    struct
    {
        const IL2C_EXECUTION_FRAME* pNext__;
        const uint16_t objRefCount__;
        const uint16_t valueCount__;
        System_String* stack0_0__;
    } frame__ = { NULL, 1, 0 };
    il2c_link_execution_frame(&frame__);

    frame__.stack0_0__ = string0__;
    System_Console_WriteLine_10(frame__.stack0_0__);
    il2c_unlink_execution_frame(&frame__);
    return;
}
