Compiler Design Assignment

Introduction

Compiler made to convert C like code to xsm executable. 
xsm executable can be directly run on xsm machine(https://exposnitc.github.io/). 

How?

Source code is converted to a Tree.

Source code undergoes lexical analysis in which we detect "is program syntatically correct.". 
If it not then exits with error.
If no error , a tree is constructed with root node as program(main program). 

Example

    Expression Node

            *
           / \
          4   5

Code Generated for each node recursively

Lexing program again?

XSM don't have labels like nasm and all. 
So labels should be changed according to program counter(instruction position).
