In order to achieve higher performance on such devices, compiler optimization is effective. However, if the original source code is not available, optimization cannot be applied. In this paper, we propose a method to convert ARM64 machine code into code written in LLVM IR, which is an intermediate representation used in LLVM compiler infrastructure, for the purpose of optimizing 64-bit ARM machine language binaries. This method transforms ARM64 machine code into LLVM IR with easy to analyze and transform loops, by analyzing the offset and size of stack variables on each function, and by simplifying the calculation of whether conditional branches are taken or not.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-06-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2024-ARC-257"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":234549,"updated":"2025-01-19T09:46:25.171242+00:00","links":{}}
