--function definitions--
if input is the main function - process

otherwise if input is not main function -process

main process
	check function declaration for accuracy
	open a fresh scope if needed
	set flags if needed
	generate code

not main process
	if name exists in symbol table and is a function
	check function definition against declaration/usage
	if all check went through
		open a fresh scope if needed
		set flags if needed
		create all parameters and install in symbol table
		generate code
		
		
--function declarations--

if input is the main function then -- process

otherwise if another function then -- process

main process
	check function definition accuracy for main
other function process
	if function doesn't already exist in symbol table
		create a new function table entry
		install into symbol table
	if a similar symbol was found in the symbol table
		check symbol table existing against new
		making sure declarations match
