c++ - Compile small functions by DM C++ Compiler

I have a small function, likes that:

float my_func(float x)
{
return x*x*x;
}

How I can compile this into machine codes by DM C++ Compiler?
PS: full functions likes main() i can compile.

I think this should do the trick:
dmc -cod -c float.cpp

I don't have obj2asm so I can't really test it.

After that operations I get *.obj - file. I dont now that I will do with this
file!!! I am stupid??? Describe me please!

Symply, I want:
I have any code on C++ language:
for axample:

float my_fync(float x, float y, float z)
{
return (x*y+z*x)*sin(x);
}

And I want to get machine code likely this:

00000	d9 44 24 04	           fld	 DWORD PTR _time$[esp-4]
00004	d8 89 08 04 00  00     fmul	 DWORD PTR [ecx+1032]
0000a	d9 99 04 04 00  00     fstp	 DWORD PTR [ecx+1028]
00010	c2 04 00	           ret	 4
(Generated by MSVC++)

BUT generated by DM C++ Compiler!!!

Help me PLEASE!!

PS: Sory for my english.

You wrote that you were able to get the machine code when you have
an main, my fix is only to get it without the main.

To get the machine code you need obj2asm from the "Extended Utility
Package":

Sorry for mine, my first language is danish.
