Added Virtual Stack Management and Symbol Tables

LOGICAL COMMANDS

Added Logical Commands

and , or , xor , lshift , rshift

Command Format :

and .data var1 var2 .result

and .value val1 val2 .xword

and .result val1 .result

and .xword val1 .result

Same format for or & xor commands

Generic Format : keyword flag operand1 operand2 output

(operand2 is unnecessary when flag is .result or .xword

Implementation :

The add , sub , mul , div , mod , and , or , xor operations use a quad_operand_line_parser() which does parses a line and generates 4 operands alongside storing the Bytecode

They are also executed via the unified_arithmetic_core() which arranges operands and resolves Keywords , Flags , Data , Outputs using switches

QUAD OPERAND PARSER

Parser Helper Function used for add , sub , mul , div , mod , or , and , xor , rshift , lshift

UNIFIED ARITHMETIC CORE

Arithmetic Handler Function for execution of arithmetic and logical operations

VIRTUAL STACK AND VARIABLES

Added Virtual Stack and Symbol table

user defined symbols i.e. 8-bit variables can be created in Micro Virtual - R

Commands :

.define

.assign

.copy

Format :

.define symbol : Define a variable

.assign symbol data : Assign 8-bit data to a defined variable

.copy symbol1 symbol1 : Copy data of one defined variable to another defined variable.

Behavior :
- - Only 10 Symbols can be defined , defining symbols with the exact same name produces undefined state (Needs Fix)
  - Symbols defined exactly the same as keywords will be treated as low priority in functions which accept both.
  - Symbols defined are always auto initialized to 0
