Hi, I whant to know, how the C++/CLI compiler works, I generate 5 tree dumps of one simple code in C++/CLI

3 tree dumps I generate with this simple code ( pure, safe CLR):

using namespace System;

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");
    return 0;
}

so, but, when I compile the code with a ' printf '... the code generate of CLR and PURE use this instruction:

|___[STM] printf : vararg int32 modopt([mscorlib]System.Runtime.CompilerServices.CallConvCdecl)(int8 modopt([mscorlib]System.Runtime.CompilerServices.IsSignUnspecifiedByte) modopt([mscorlib]System.Runtime.CompilerServices.IsConst)*)

The IL code generate is this:

//000008: 	printf("Ola mundo\n");
  IL_000a:  /* 7F   | (04)000001       */ ldsflda    valuetype '<CppImplementationDetails>'.$ArrayType$$$BY0L@$$CBD/*02000002*/ modopt([mscorlib/*23000001*/]System.Runtime.CompilerServices.IsConst/*01000002*/) '?A0x1af50272.unnamed-global-0' /* 04000001 */
  IL_000f:  /* 28   | (0A)000004       */ call       vararg int32 modopt([mscorlib/*23000001*/]System.Runtime.CompilerServices.CallConvCdecl/*01000001*/) printf(int8 modopt([mscorlib/*23000001*/]System.Runtime.CompilerServices.IsSignUnspecifiedByte/*01000006*/) modopt([mscorlib/*23000001*/]System.Runtime.CompilerServices.IsConst/*01000002*/)*) /* 0A000004 */
  IL_0014:  /* 26   |                  */ pop

So, In my attempt of development of one compiler with this style, I found one compiler called pnetC, of NetGnu, this compile mix C Native code with MSIL,but, the compiler use one dll with all .h files...

So, I would like techniques information of this compiler style, how I can generate this mixed code ?

So, basically, I need ideias for this, and technical informations of this...

Thanks
