pragma unroll texture Windows vs Linux

Hi!

I’m doing the following code:

uchar4 pixel;

#pragma unroll 4

for(i = 0; i < 32; i++)

{

  (...)

   pixel = tex2D(...)

  (...)

}

In Linux (Ubuntu):

–> error: Loop was not unrolled, inline assembly

In Windows (Win7-64):

–> it Compiles and executes perfectly. Moreover, if you see the PTX code, this is unrolled and the loop in ptx have 8 iterations as we are waiting.

I thought that a loop couldn’t be unrolled if it had texture calls but, to Windows don’t mind it! Does Anyone know anything about this?

Thanks in advance,

Regards.
