The various kinds of intermediate representations for intermediate code generation:a) Syntax treesb) Postfix notationc) Three address code
a) Re targeting is facilitated; a compiler for a different machine can be created by attaching a back end for the new machine to an existing front end.b) A machine-independent…
In many compilers the source code is translated into a language which is intermediate in complexity between a high-level programming language and machine code. Such a language is therefore called…
If G is a grammar with start symbol S, then G’, the augmented grammar for G, is G with a new start symbol S’ and production S’ ->S. It is…
A grammar whose parsing table has no multiply-defined entries is said to be LL(1).
A predictive parser is an efficient way of implementing recursive_descent parsing by handling the stack of activation records explicitly. The predictive parser has an input, a stack , a parsing…
A parser that uses a set of recursive procedures to recognize its input with non backtracking is called a recursive-descent parser. The recursive procedures can be quite easy to write.
The problems in top down parsinga) Left recursion.b) Backtracking.c) The order in which alternates are tried can affect the language accepted.
The grammars have the property that no production right side is E(absolon)or has two adjacent non terminals is called operator grammar.
