Visual C++ 6.0 Compiler settings

[BSODMASTER]

So I want to know how to compile this code:

void AddToCentre(float a0,float & a1,float & a2)
{
	if(-50.0f >= a2 && 50.0f >= a2 && -50.0f >= a0 && a0 >= 50.0f && a0 > a1 - 2.0f && a0 > a1 + 2.0f )
	{ 
		a2 = a0;
		a1 = a0;
	}
	else
	{
		a2 = 0; 
		a1 = a0; 
	}
}

To look like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

If you know what you want the assembly to look like, why not just stick that right in there?

Btw use some decent compiler, not VS6, it's from 1998 for god's sake :(

[kbw]

Why not write the function in assembler? If you use SP5 on VS6, you can install the Processor Pack that has masm.

You maybe not understand me right. I want to configure the VC++ 6.0 Compiler to produce the same asm code in the 1st ASM snapshot made with IDA PRO. Those 2 ASM snapshots are made on EXEs compiled both with VC++ 6.0 without inline ASM (I think). The difference is that I don't have the project and the source for the first exe. Any help? I tried using full optimization but no luck, maybe other compiler setting or new SP or the source code is not that?

[BSODMASTER]

Anyway I Installed the Processor Pack and the problem sloved but now I want to ask something - how to install the intel compiler on VC++ 6.0 SP5 to compiler programs with SSE instructions for Pentium 3 or for Pentium 4. The compiler need to be about 2000~2003 year released. Please help.
