Abstract: Performance of a program written in dynamic languages is improved through the use of a compiler that provides type inference for methods having a user-defined element. The user-defined element may be an input in a user-defined type. Though, the user-defined element may reflect that the method is user-defined. Type inference may be performed based on a user-defined mapping, relating input types to output types for one or more methods. The mapping may be specified as a data table provided to the compiler or as one or more functions that register with the compiler such that, as the compiler processes portions of a source program and detects a method with a user-defined element, the compiler may access the mapping and infer the type of an output of the method. The inferred type may then be used to optimize code dependent on that output.

Abstract: A reusable expression graph system and method that generates reusable expression graphs that can be used with potentially different input parameters in order to achieve computational efficiency and ease of programming. Reusable expression graph mitigate the need to rebuild an expression for each new value. This is achieved in part by creating a node called a “parameter node.” The parameter node acts as a generic placeholder for a leaf node in the expression graph. In addition, the parameter node acts as a proxy for a bindable term of the leaf node, and the bindable term can be either a value or one or more additional expressions. The parameter node then is bound to the bindable term and the expression is evaluated with that bindable term instead of the placeholder. The parameter node created by embodiments of the reusable expression graph system and method works across many different programming languages.

Abstract: A system and method for analyzing a concurrent program employ asynchronous function calls for communication and recursion. A control flow graph is constructed based on a context-sensitive pointer analysis, whereupon encountering a function pointer, a points-to set of the function pointer is computed in a context-sensitive fashion to determine a set of potential function calls. The context-sensitive pointer analysis is terminated when no new potential function calls are encountered and where the potential function calls may contribute new data races other than those that exist in the contexts traversed thus far. To decide this, a characterization of pointer aliasing based upon complete update sequences is employed. A set of contexts that may contribute to different data races are enumerated by tracking update sequences for function and lock pointers and pointers that are shared or point to shared memory locations. Data race detection is carried out on the control flow graph.

Abstract: Disclosed are embodiments a computer-implemented method, a system and an associated program storage device that provide for automatic programming language grammar partitioning to solve the “code too large” problem. The embodiments partition a particular programming language grammar into logical subsets based on a set of partitioning heuristics and using a dependency graph that is preprocessed so as to be devoid of any cyclically connected grammar rule nodes. For each logical subset, textual code for a corresponding portion of a parsing program can be generated and then converted into machine-readable code for that corresponding portion of the parsing program. Thus, small amounts of textual code for portions of a parsing program are discretely converted into machine-readable code, thereby avoiding the “code too large” problem. The machine-readable code for all portions of the parsing program can then be merged and the parsing program can be executed in order to parse a corpus.

Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for selecting a first grammar rule in a programming language grammar. The grammar is used for determining a syntax validity of a programming code statement in a text editor and the first grammar rule includes a hard-to-type symbol that is syntactically correct for the programming code statement. A second grammar rule for the grammar is created. The created second grammar rule is substantially identical to the first grammar rule but the hard-to-type symbol is replaced with an easy-to-type symbol that is syntactically incorrect for the programming code statement. An action is associated with the grammar and is performed upon satisfying the second grammar rule. Performance of the second grammar rule causes the easy-to-type symbol in the programming code statement in the text editor to be replaced with the hard-to-type symbol.

Abstract: There is described a method of compiling source code for a computer program into corresponding object code. The source code includes several declared variables. The method comprises, for each declared variable in the source code, including in the object code a declaration statement indicating an associated memory location for that variable and indicating the position in the object code of the next declaration statement.

Abstract: Declarations from an input source code are serialized into a stream of tokens produced by following each branch of a preprocessor conditional directive statement that interrupts a declaration. Tokens are labeled with a parsing path indicator corresponding to a parsing path induced by branches of a preprocessor conditional directive. The declarations that are formed along the different parsing paths are serialized by fetching the tokens that belong to the first parsing path in a first pass, and passing the tokens on to a next phase of a compiler. The pointer that marks the next token is repositioned to return to the start of the declaration. The declaration may be serialized again through the second parsing path in a second pass. The operation may be repeated until each of the parsing paths induced by the presence of branches of the preprocessor conditional directives in the source code is exhausted.
