So, in the development of such programs, size reduction is often in need, but manual reduction is costly. In order to reduce the size automatically, many optimizations have beed invented, and one of them is procedural abstraction. Procedural abstraction reduces the size by summarizing instruction sequence repeatedly apper in the program. Because it uses a call instruction to transfer the control to the summarized instruction sequence, it needs methods to manage the side effects the call instruction causes. In this paper, we present the method for architectures whose call instruction puts the return address on the stack. We implemented our method for one of the architectures, namely the RL78 microcontroller, and evaluated using practical programs to show that our method reduce the code size by 0.95%.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"10","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-01-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"15"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":214568,"updated":"2025-01-19T16:33:49.610716+00:00","links":{},"created":"2025-01-19T01:15:22.759252+00:00"}
