should not issue an error in lexical and syntax analysis phase, as it is lexically and structurally correct, but it should generate a semantic error as the type of the assignment differs. These rules are set by the grammar of the language and evaluated in semantic analysis. The following ...
When an error occurs, the compiler deletes input tokens until it finds a safe symbol, and then “backs the parser out” (e.g., returns from recursive descent subroutines) until it finds a context in which that symbol might appear. Phrase-level recovery improves on this technique by ...
Furthermore, runtime errors are possible in SQL, e.g., in some contexts, SQL queries or subqueries must return not more than one row. The occurrence of this error depends on the database state (the data), therefore it is not necessarily found during testing. Certainly it would be good ...
A set of functional queries are made over the semantic objects302by the semantic analysis engine202. Examples in a compiler may include the binding of a name or the set of members of a type. In response to a query, the engine interrogates a cache206where the answer would reside. If an ...
Profilers may be part of an Integrated Development Environment (IDE) which also includes a compiler, a debugger, an editor, and other program development tools.Although application programs are often profiled, other kinds of “programs” (in a broad sense of the word, which is used herein) ...
Smart contracts are programs running on cryptocurrency (e.g., Ethereum) blockchains, whose popularity stem from the possibility to perform financial transactions, such as payments and auctions, in a distributed environment without need for any trusted th
In this study, we use a strategy of SLR accomplished by the methodology proposed by [44].Figure 4shows the SLR steps. We define the review requirements and research questions during the planning process. We identify, select, and analyze the related studies in the searching phase. Then, the ...
Distinguishing features of DSMLs are—Concrete syntax is often graphical, structures of phrases are often defined with metamodels instead of CFGs, and often used in an earlier software development phase (design phase instead of implementation phase). The MetAmodel Recovery System (MARS) [29] was...
