Although programmers are using assembly languages or intrinsic routines on coding hot spots of the programs to exploit the SIMD instructions, compilers should generate SIMD codes automatically for portability and maintainability of the programs. “Integral promotion” rule in a high level language often becomes an obstacle for discovering code fragments which can be translated into appropriate SIMD instructions. If compilers obey the rule strictly, they cannot translate the fragments into the SIMD instructions as the programmers does in assembly languages, etc. In this paper, we present a code analysis method based on “data size inference”. It increases translatability and parallelism in using the SIMD instructions, while it guarantees the same result as the integral promotion rule is strictly obeyed.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"11","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":"2004-05-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG05(PRO21)","bibliographicVolumeNumber":"45"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":16682,"links":{}}
