  2. Semantic analysis (compilers) - Wikipedia

    en.wikipedia.org/wiki/Semantic_analysis_(compilers)

    Semantic analysis or context sensitive analysis is a process in compiler construction, usually after parsing, to gather necessary semantic information from the source code. [1] It usually includes type checking , or makes sure a variable is declared before use which is impossible to describe in the extended Backus–Naur form and thus not ...

  3. Roslyn (compiler) - Wikipedia

    en.wikipedia.org/wiki/Roslyn_(compiler)

    The compilers are available via the traditional command-line programs but also as APIs available natively from within .NET code. Roslyn exposes modules for syntactic ( lexical ) analysis of code, semantic analysis, dynamic compilation to CIL , and code emission.

  4. Lexer hack - Wikipedia

    en.wikipedia.org/wiki/Lexer_hack

    Lexer hack is frowned upon in modern compilers as it creates tight coupling between otherwise largely independent steps in the compilation process. Instead, identifier-like tokens are tokenized as identifiers and later disambiguated by the parser, allowing cleaner separation of concerns .

  5. Semantics (computer science) - Wikipedia

    en.wikipedia.org/wiki/Semantics_(computer_science)

    Denotational semantic descriptions can also serve as compositional translations from a programming language into the denotational metalanguage and used as a basis for designing compilers. Operational semantics, [7] whereby the execution of the language is described directly (rather than by translation).

  6. Compiler - Wikipedia

    en.wikipedia.org/wiki/Compiler

    Compiler analysis is the prerequisite for any compiler optimization, and they tightly work together. For example, dependence analysis is crucial for loop transformation. The scope of compiler analysis and optimizations vary greatly; their scope may range from operating within a basic block, to whole procedures, or even the whole program. There ...

  7. Abstract syntax tree - Wikipedia

    en.wikipedia.org/wiki/Abstract_syntax_tree

    The AST is used intensively during semantic analysis, where the compiler checks for correct usage of the elements of the program and the language. The compiler also generates symbol tables based on the AST during semantic analysis. A complete traversal of the tree allows verification of the correctness of the program.

  9. DIANA (intermediate language) - Wikipedia

    en.wikipedia.org/wiki/DIANA_(intermediate_language)

    It was originally designed as an interface between the compiler front end (syntactic analysis) and middle end (semantic analysis) of the compiler on the one hand and the compiler back end (code generation and optimization) on the other.
