LR Parser in Compiler Design

LR Parser The most popular type of bottom-up parsing is LR(K) parsing. The LR() parser scans the input from left – to – right, which is the actual abbreviation of L in the LR(K) parser. However, the R in the LR() parser constructs the rightmost derivation in the...

Lexical Analysis in Compiler Design

Lexical Analysis It is the first phase of the compiler. As we know, it is also known as a scanner. The input for lexical analysis is source code. After taking source code as an input, it breaks them into valid tokens by removing whitespace, comment from source code....

Bottom-Up Parsing in Compiler Design

Bottom-Up Parsing A bottom-up parsing constructs the parse tree for an input string beginning from the bottom (the leaves) and moves to work towards the top (the root). Bottom-up parsing is a parser that reduces the string to the start symbol of the grammar....

Phases of Compiler

Phases of Compiler The compilation process of a compiler goes through various phases. Each phase of the compiler takes the output from the previous as an input. Here we will see all the phases of a compiler:  Linguistic/Lexical Analysis: The first phase of the...
