Compilers lab, Jan'16 - Apr'16

There were total 4 assignemnts in this lab.

#Assignment 1 Designed a simple grammer with the following features:

(i)		assignments, id := expr

(ii)	condistions, if expr then expr2

(iii)	loop, while expr do stmt

(iv)	compound statement, begin opt_stmts end

(v)		Arithmetic and relational operator.

And developed a simple compiler that generates x85 code.

#Assignment 2

Part(a) Write a C code to convert a regular expression into minimised DFA.

Part(b) Write a Grammer for the compiler and do its lexical analysis.

#Assignment 3 Perform changes in the grammer if needed. Perform Parsing of the grammer developed in Assignment 2.

#Assigment 4

Build Complete Compiler for the grammer previously decided. Perform Syntax, semantic analysis and Did Code generation (to x86).

Code Refactoring is Required.
