π The symbol table is used by various phases of the compiler to store information gathered from the analysis phase and used in the synthesis phase.
π The symbol table manager gathers information from the analysis phase and stores it in the symbol table for use by the synthesis phase.
π» The symbol table allows for various operations to be performed, such as adding, retrieving, and modifying entries.
π The symbol table is maintained by compilers to store information about entities such as variables and functions.
π During lexical analysis, the symbol table is used to create entries for identifiers.
π§ The symbol table is updated and used by different phases of the compiler in order to generate target code.
π The symbol table is used during intermediate code generation, code optimization, and target code generation phases.
π‘ The symbol table stores information about identifiers, such as their names, data types, and sizes.
π₯οΈ The symbol table is essential for generating target code using the address information of identifiers.
π The 'dimension' attribute holds the dimensions of arrays.
π€ The 'line of declaration' attribute stores the line number where the identifier is declared.
π’ The 'line of usage' attribute stores the line numbers where the identifier is used.
π The symbol table is used to keep track of variables and their attributes in a program.
π Variables can have different attributes such as name, type, and size.
π’ The size of an array can be determined by counting the number of characters it contains.
π The symbol table is a data structure used in programming languages to store information about variables and identifiers.
π‘ The size of the symbol table is dynamically allocated during compile time to prevent wasted space.
π In non-block structured languages like Fortran, variables have a global scope and can be inserted or accessed in the symbol table.
π In C, variables can be declared multiple times within different blocks using curly braces for block structure.
π The symbol table allows for insert and lookup operations to handle variable declarations.
π The set and reset operations define and redefine the scopes of variables declared multiple times.
