Fortran + MASM (using SSE2)

[desmo3re]

Solution: a previous MUL operation used edx also if there was no overflaw. So I rewrite the correct address in edx and there are no more access violations! :U
Now I have to write some value in the vector to test if the routine writes the result in the corrept positions!

How can I calculate the absolute value of a double precision floating stored in the low part of an XMM register? I've seen that there are FABS and PABSB/D/W instructions, but FABS acts on ST(0) and PABS only on integer values.
Do you have any suggestion?

Should just be a simple bitwise AND with 7FFFFFFFh on float32's ..

Yesterday night I thought to this simple solution, but I was no more in front of my computer to see the manual. So I can write the correct 128 bit mask in a XMM register and perform an ANDPD instruction with my data contained in another XMM register. I think that this should be the right solution, I will make a test.
Thank you one more time Rockoon!
