About
======================================================================
This program simulates a compiler for the language PL/0. It parses
the syntax of an input file with PL/0 code and generates assembly
code that is interpreted by a virtual machine.
The compiler will generate errors and will fail to compile if the
given code is not syntatically correct. Otherwise, the compiler
prints a confirmation that the code is syntatically correct.
Note that the compiler is not fully representative of PL/0 as there
are several functions (e.g. procedures) that are not implemented in
its current form.

How to execute
======================================================================
compile: gcc -std=c99 compiler.c
execution: ./a.out <optional flags>
flags:
----------------------------------------------------------------
-f <filename> : Takes a specified input file. *
-l : Prints list of lexemes/tokens.
-a : Prints generated assembly code.
-v : Prints virtual machine execution trace.
* Default input file found at constant 'IN' in compiler.h
