In most cases, these compilers have been developed by modifying runtime system or by re-implementing runtime system. Therefore a large amount of development cost is needed to develop compilers for scripting languages. On this background, we developed CastOff, a compiler for the Ruby scripting language. By using features in Ruby, we developed CastOff without modifying the Ruby runtime system. CastOff has a lot of functions such as runtime compilation, reuse of compiled codes, profiling execution, annotation support, deoptimization and re-compilation. CastOff is a Ruby compiler with the above features provided as a Ruby's C extension library. In this paper, we show the detailed design and implementation of CastOff, how we implemented functions of CastOff by Ruby's C extension library. Moreover, we discuss functions required in the runtime system for developing a compiler as a library like CastOff.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"22","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":"2012-08-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"5"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:36:59.428343+00:00","id":83510,"links":{}}
