How to debug the function that the compiler emited

[hbc...@126.com]

the compiler can emit function that I want and the result is right. But when I want to debug the function that compiler emited with visual studio, I found that I can't debug it.

Does anyone know how to debug the function that the compiler emited.

this is my test code.

int add(int value1, int value2)

{

cout << "arg1: " << value1 << "  arg2: " << value2 << endl;

return value1 + value2;

}

int main(int argc, char* argv[])

{

int value3 = add(1, 2);

cout << value3 << endl;

X86Compiler c;

FileLogger Logger(stdout);

c.setLogger(&Logger);

c.newFunc(kX86FuncConvDefault, FuncBuilder1<void, int>());

GpVar result(c.newGpVar());

c.push(Imm(9));

c.push(Imm(10));

c.call((void*)add);

//c.mov(dword_ptr(result), eax);

c.endFunc();

typedef void (*myfun)(void);

myfun fun = asmjit_cast<myfun>(c.make());

fun();

__asm{

mov value3, eax

}

cout << value3 << endl;

MemoryManager::getGlobal()->free(fun);

return 0;

}

Put it in an X86 emulator.

When your hammer is C++, everything begins to look like a thumb.

Or just step into the “fun()” call with the disassembly view open; so that you’re stepping into the actual call instruction.

Can't believe I didn't think of that...

I can step into the "fun()" call, but I can't see the actual call instruction.

I can only see a lot of question marks.

I have the same problem with VS2012. Sometimes it shows questionmarks instead of emitted code. This usually happens at the beginning of emitted code, but after few bytes it shows code properly.

This seems to be some bug of VS.
