Created attachment 87554 [details] piglit test showing importance of parameter order The order of parameters for long seems to matter. Output for the attached piglit test (failing tests on top): > Running kernel test: Arg0 = a + b Using kernel add0 Setting kernel arguments... Running the kernel... Validating results... Expecting 3 (0x3) with tolerance 0, but got 12884901888 (0x300000000) Error at long[0] Argument 0: FAIL PIGLIT:subtest {'Arg0 = a + b' : 'fail'} > Running kernel test: Arg1 = a + b Using kernel add1 Setting kernel arguments...
