"ptxas fatal" error for variable assignement

Hi,

I have this error by changing static value in the kernel by arg value :

Log = ptxas application ptx input, line 57; error : Argument 1 of instuction ‘selp’: must be register

ptxas application ptx input, line 57; error : Argument 2 of instuction ‘selp’: must be register

ptxas fatal : Ptx assembly aborted due to errors

error : Ptx compilation failed: gpu=‘sm_13’, device code=‘anonymous_jit_identity’

: Retrieving binary for ‘anonymous_jit_identity’, for gpu=‘sm_13’, usage mode=’’

: Considering profile ‘compute_10’ for gpu=‘sm_13’ in ‘anonymous_jit_identity’

: Control flags for ‘anonymous_jit_identity’ disable search path

: Ptx binary found for ‘anonymous_jit_identity’, architecture=‘compute_10’

: Ptx compilation for ‘anonymous_jit_identity’, for gpu=‘sm_13’, ocg options=’’

My kernel :

Code:

#define TYPE short

__kernel void threshold(__global const TYPE *inputBuffer, __global TYPE *outputBuffer, const TYPE insideValue, const TYPE outsideValue, const TYPE thresholdHighValue, const TYPE thresholdLowValue)

{

int location = get_global_id(0);

TYPE pixel ;

if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)

{

pixel = insideValue; // works if pixel =1000

}

else

{

pixel = outsideValue;

}

outputBuffer[location] = pixel;

}

The following codes work if pixel value is static:

Code:

if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)

{

pixel = 1000;

}

else

{

pixel = 0;

}

Code:

if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)

{

pixel = insideValue;

}

else

{

pixel = 0;

}

Code:

if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)

{

pixel = 1000;

}

else

{

pixel = outsideValue;

}

, but not with both, insideValue, outsideValue together.

Every part of code for “insideValue, outsideValue, thresholdHighValue, thresholdLowValue” are the same and all values are read well before sending to GPU.

GPU : GTX 285

Did you have any idea on this issue.

Thanks.
