| Abstract(in English) | This article presents random testing of C compilers focusing on arithmetic optimization. It tests if code generation and optimization are properly performed for integer arithmetic expressions containing various integer type variables and implicit casting. The types and the initial values of the variables are randomly selected and the arithmetic expressions are randomly composed to form a test program. The expected values of the expressions are precomputed by the random test program generator so that the comparison between the computed values and the expected values is done within the test program. During the preparation of the expected values, all the intermediate values are tested so that the generator do not produce programs that results in undefined behavior by zero division, overflow, nor left-shift of negative values, etc. An implemented random test system successfully detected a bug in GCC 4.1.2 for x86. |
