Syntax defines what programs are—their "shape" or "structure". Semantics defines what programs mean—how they behave, how they evaluate. We saw that we can represent the syntax of a program as an ...

To support syntax-directed, or modular, program development and analysis a semantics needs to be compositional. In addition to its role in validating program correctness, semantics can provide a firm ...

Implementation of the lexical, syntax and semantic analysis stages of a typical C/C++ compiler. The program is able to read a sample C/C++ code and process and analyze the source file to find errors ...

We present an algorithm for specifying and sampling from distributions over programs via a perturb-max approximation. Prior work is generally limited to sampling from priors over program syntax (for ...

Novel techniques have been proposed to compute syntactically minimal program fixes, but the smallest syntactic fix to a program can still significantly alter the original program’s behavior. We ...
