Abstract (in Japanese) (See Japanese page) 
(in English) Recently, mobile devices and embedded devices equipped with processing devices such as multicore processor and GPU are becoming popular. In order to make full use of these devices, it is necessary to optimize the program according to the environment of the device. We are developing a LLVM based system that automatically optimizes ARM binary code according to the environment of the device. Optimization processing of LLVM is performed for LLVM IR. Therefore, ARM machine code front end which translates ARM machine code into LLVM IR is important. For later optimization, the translated LLVM IR needs to be an expression that can be optimized but it is not self explanatory. In this paper, we considerate translation method that generate IR equivalent to IR generated from source code and show the result of applying the method.
