Compiler Design

Syntax analyzers follow production rules defined by means of context-free grammar. The way the production rules are implemented (derivation) divides parsing into two types : top-down parsing and bottom-up parsing.…

In the Above Chapter of compiler design Semantic Analysis we have learnt how a parser constructs parse trees in the syntax analysis phase. The plain parse-tree constructed in that phase…

Compiler Design Code Optimization is a program transformation technique, which tries to improve the code by making it consume less resources (i.e. CPU, Memory) and deliver high speed. In optimization,…

Compiler Design Code generation can be considered as the final phase of compilation. Through post code generation, optimization process can be applied on the code, but that can be seen…

A source code in compiler Intermediate code generation can directly be translated into its target machine code, then why at all we need to translate the source code into an…

Compiler Design Symbol table is an important data structure created and maintained by compilers in order to store information about the occurrence of various entities such as variable names, function…

In Compiler Design Run-time Environment a program as a source code is merely a collection of text (code, statements etc.) and to make it alive, it requires actions to be…

A parser should be able to detect and report any Compiler Design error recovery in the program. It is expected that when an error is encountered, the parser should be…

Compiler Design Bottom-up parser starts from the leaf nodes of a tree and works in upward direction till it reaches the root node. Here, we start from a sentence and…

We have learned in the last chapter of Compiler design Top-down parser that the top-down parsing technique parses the input, and starts constructing a parse tree from the root node…
