Testing of Optimization Performance of Android DEX Compilers Based on Native Code Comparison

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a method for testing optimizing performance of Android DEX compilers based on comparison of resulting native codes. By comparing object codes generated from class files by DEX compilers dx and d8, detection of missed optimization by the newer d8 is attemted. The code comparison is made on native codes
which are produced by the back-end compiler of the ART (Android Runtime) from the byte codes generated by dx and d8. The test class files to dx and d8 are obtained by compiling random Java programs generated by Orange4. A test system based on the proposed method has successfully detected missed optimization in $x86_64$ native codes originated from d8.
