| | Symbol table - Wikipedia, the free encyclopedia |
 | | In computer science, a symbol table is a data structure used by a language translator such as a compiler or interpreter, where each symbol in a program's source code is associated with information such as location, type and scope level. | | | A symbol table can be a transient structure used only during a language translation process and then discarded, or it can be embedded in the output of that process for later exploitation, for example, during an interactive debugging session, or as a resource for formatting a diagnostic report during or after execution of a program. | | | A hash table implementation of a symbol table is common and the table is usually maintained throughout all phases of translation. |

| | CS 434 Lecture Notes -- Symbol Tables vs. Symbol Table Organization |
| | In the "symbol table is a hash table" view of a compiler, detecting undeclared and multiply declared identifiers becomes a task split between the scanner, parser and symbol table routines. | | | The hash table (or whatever else is used) is simply a mechanism that enables the scanner to associate symbol table entries with the character string form of identifiers it processes. | | | The standard approach to explaining symbol table organization, however, adds additional complexity by failing to properly distinguish the role of the scanner in building the symbol table from that of the semantic analysis routines in completing it. |

| | STABS - Symbol information in symbol tables |
| | Symbol table entries with n_type fields containing a value greater or equal to 0x20 originated as stabs generated by the compiler (with one random exception). | | | Those with n_type values less than 0x20 were placed in the symbol table of the executable by the assembler or the linker. | | | The variable is represented by the following two symbol table entries in the object file. |

| | Symbol Table Library |
| | A structure is defined in a separate symbol table and variables of that type may be handled by passing a smart pointer with the table fork pointing to the symbol table and the object fork pointing to a table. | | | The symbol table library provides a means of writing object oriented code in C. It allows you to define classes and methods which operate on those classes. | | | Overlays Allow one symbol table to be placed on top of another in such a way that the result is the combination of two tables with one overiding the other. |

| | Symbol Table Management |
| | The symbol table carries the collected information about each named object in the program to other phases of the compiler. | | | The table lookup needs to be as fast as possible. | | | As soon as a named token is found, depending on the token type, a call to the symbol table routines is made. |

| | 7.5 Other Symbol Table Techniques |
| | Symbol table information or pointers to symbol table information can be attached to the nodes of the parse tree or abstract syntax tree. | | | Thus the symbol table structures such as a stack, which can discard the table information for nested procedures as soon as they are processed, are useful. | | | Thus, the symbol table implementation is dependent on the language constructs found in this language. |

| | Symbols |
| | When the symbol table successfully matches something from the input, the data associated with the matching entry in the symbol table is reported to the semantic action. | | | On success, the matching portion of the input is added to the symbol table. | | | Traditionally, symbol table management is maintained seperately outside the BNF grammar through semantic actions. |

| | Java Symbol Table Design Issues |
| | The symbol table and the semantic analysis code that checks the Java AST returned by the parser must be able to resolve whether a symbol definition is semantically correct. | | | The term "symbol table" is generic and usually refers to a data structure that is much more complex than a table (e.g., an array of structures). | | | The symbol table must also be efficient so compiler performance is not hurt by symbol table lookup in the front end. |

| | A symbol table is an instance of class SymTab whose find function returns a pointer to the item in which its input symbol is stored. | | | The function insert performs the same function as find except that it always returns a pointer to the item instance for the symbol because it creates a new instance of item for a symbol that is not stored in the table, and then stores it in the table before returning. | | | Of course, the information for this print out is retrieved from the symbol table generated by the processing of InSymbols. |
