Symbol table. In computer science, a symbol table is a data structure used by a language translator such as a compiler or interpreter, where each identifier (or symbol), constant, procedure and function in a program's source code is associated with information relating to its declaration or appearance in the source.
Compiler structure; Lexical analysis (including regular expressions and finite automata) Syntax analysis (including context-free grammars, LL parsers, bottom-up parsers, and LR parsers) Syntax-directed translation; Type checking (including type conversions and polymorphism) Run-time environment (including parameter passing, symbol tables and ...
Abstract syntax tree. An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a type of intermediate representation (IR) where each variable is assigned exactly once. SSA is used in most high-quality optimizing compilers for imperative languages, including LLVM, the GNU Compiler Collection, and many commercial compilers.
One of the most important difference between C and Pascal is the way they handle the parameters on stack during a subroutine call : This is called the calling convention : PASCAL-style parameters are pushed on the stack in left-to-right order. The STDCALL calling convention of C pushes the parameters on the stack in right-to-left order.
Calling convention. In computer science, a calling convention is an implementation -level (low-level) scheme for how subroutines or functions receive parameters from their caller and how they return a result. [1] When some code calls a function, design choices have been taken for where and how parameters are passed to that function, and where ...
In computer programming, a parameter or a formal argument is a special kind of variable used in a subroutine to refer to one of the pieces of data provided as input to the subroutine. [ a ][ 1 ] These pieces of data are the values [ 2 ][ 3 ][ 4 ] of the arguments (often called actual arguments or actual parameters) with which the subroutine is ...
ISBN. 0-201-00022-9. Principles of Compiler Design, by Alfred Aho and Jeffrey Ullman, is a classic textbook on compilers for computer programming languages. Both of the authors won the 2020 Turing award for their work on compilers. It is often called the " green dragon book " [1] and its cover depicts a knight and a dragon in battle; the dragon ...
