The system consists of:• a syntax-directed transducer, which embodies the principle of compositionality,• a type checker, which is extremely useful in debugging semantic definitions, and• an interface to the yacc parser-generator, which allows the system to use concrete syntax rather than the often cumbersome abstract syntax for its programs.In this paper, we discuss the design of the system, its implementation, and discuss its use.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127519107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A scope stack and an unstructured name space are used to facilitate separate compilation and ensure that each Ada declaration takes a constant unit of time. Visibility issues affect practically every aspect of semantic analysis in Ada: declarations, statements, expressions, and separate compilation. The design of the symbol table package is, thus, a critical one. In this paper, I discuss the design goals of the symbol table for the Ada Integrated Environment (AIE) bootstrap compiler front end, and how they were influenced by the Ada language. Since the compiler is being heavily used by the AIE project, we have ample data with which to measure symbol table performance.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123340395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sub-protocol-evaluators can be built for any non-circular attribute grammar; this paper describes how to construct them for absolutely noncircular grammars [4]. Sub-protocol-evaluators are most easily understood as a simple optimization of another evaluator we call the protocol-evaluator. The protocol-evaluator has elements in common with the tree-walk evaluator of Kennedy-Warren [4] and with Nielson's direct evaluator [6]; it can be viewed as a refinement of each of these. Furthermore, the uniform AGs, proposed by Warren [9], and the ordered AGs, proposed by Kastens [3], are both subclasses of grammars for which especially efficient protocol-evaluators can be built.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129976288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A TT-grammar contains context-free grammars for describing the syntax of both languages. The transformation between the languages is described by a relationship of productions from the grammars. The TT-grammar is supported by an automated tool. SSAGS -- a translator writing system based on attribute grammars -- has been extended to support certain classes of TT-grammars. SSAGS analyzes TT-grammars and automatically generates Ada source programs implementing the transformation specified by the TT-grammar. Experience with two different restricted forms of TT-grammars is described with respect to their practical application. The experience demonstrates the readability, ease of development, and additional verification available through the use of TT-grammars.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132869175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
