Much of this work has variables with static initialization semantics. What is precisely the nature and origin of this run-time penalty?

const int x = 0 ; for both static as a linkage and a storage class specifier (i.e. inside and outside a function). The phrase "static semantics" now plays a role analogous to that played by "semantics" up to the beginning of the 1970s; it tends to be a catch-all term, covering all that is not part of the dynamic semantics, just as "semantic analysis" once covered all compiler activities other than lexical and syntactic analysis. The static semantics of a belief theory T is the set of all formulae which belong to the static completion T of T. 7 In agreement with Minker’s Generalized Closed Word Assumption GCWA) [Min82] and with McCarthy’s Circumscription [McC80], a formula F is believed to be true in the static semantics if and only if it is minimally entailed by T. associate rich static semantics with this notation, provide a realization of this notation by translating programs written in it into a “lower-level” language, and link the static semantics of the custom notation with those of the lower-level language. The framework allows this by providing a macro system with two major features: Tasks of the Semantic Analyzer •Find the declaration that defines each identifier instance •Determine the static types of expressions •Perform re-organizations of the AST that were inconvenient in parser, or required semantic information •Detect errors and fix to allow further processing Static semantic rules are enforced by a compiler at compile time Implemented in semantic analysis phase of the compiler Context-free grammars are not powerful enough to describe certain rules, such as checking variable declaration with variable use Static Semantics Most programming languages exhibit a phase distinction between the static and dynamic phases of processing. The static phase consists of parsing and type checking to ensure that the program is well-formed; the dynamic phase consists of execution of well-formed programs.

Lexical Semantics - Lexical semantics deconstruct words and phrases within a line of text to understand the meaning in terms of context. This can include a study of individual nouns, verbs, adjectives, prefixes , root words , suffixes , or longer phrases or idioms . Sometimes, we refer to static typing as the static semantics of XQuery and the determination of the meanings of expressions as the dynamic semantics. Static typing is a way of determining the data types of XQuery expressions without considering any specific data values. It includes: the static semantics, which is the part that can be ascertained at compile time, including data typing, whether all dynamic semantics, which is what actually happens when the program is executed.
The static completion¯P can be defined as the least fixed point of a naturalminimal model operator and can be constructed by means of a simpleiterative procedure. The semantics defined by the static completion¯P is called thestatic semantics ofP. It coincides with the set of sentences that are true inall static expansions ofP. The static semantics is specified by generic hypothetical judgements of the form x 1: τ 1 [χ 1], . . .

The semantics formally specifies the static semantics, which is the part that can be ascertained at compile time, including data typing, whether all variables are declared, which declaration applies to which variable in the case of scoping, what their type is, whether functions and methods are called with correct calling sequences, whether assignments are type-compatible, etc., and STATIC SEMANTICS N.

Attribute Grammar •A device used to describe more of the structure of a programming language than can be described with a context-free grammar •It provides a formal framework for decorating parse trees •An attribute grammar is an extension 2014-10-15 Static objects are constructs (identifiers, statements, expressions etc.) in the text of the program, and have no meaningful existence beyond compile-time. Dynamic objects are (instances of) values, locations and the like, which live and move and have their being inside the computer at run-time.

The static semantics defines restrictions on the structure of valid texts that are hard or impossible to express in standard syntactic formalisms. For compiled languages, static semantics essentially include those semantic rules that can be checked at compile time.
