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++ ...
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; }
View with comments / other sample translation results (contain complex results)
IL2C current status is experimental, read a simple "Getting started" for first step.
