Demo:
	ARM

Take a look at appendix B if you haven't already

Midterm review guide
	Make sure you understand the book up through chapter 10

Register review:
	eax, ebx, ecx, edx:  Main general purpose registers
	esi, edi:  source index and data index, actually general purpose
	esp, ebp:  Stack and base pointer.  esp modified automatically
		Could use ebp as a general purpose register, I guess
	eip:  Instruction Pointer
	eflags:  Flags, set with a lot of operations including cmp

The call stack, and functions and such:
	"call stack" as opposed to "a stack"
	It's a stalactite
		Not a stalagmite (the heap is)
	How big can it be?
		We could always check...
		At some point it'll segfault

Let's look at a couple functions and see what gcc does:
	We can practice drawing the stack
	With and without -fomit-frame-pointer
	With an inline function
	With optimization

Pointers:
	Everybody loves pointers!
	Can we have a function that prints an array as a bar graph?
	How about pointers to variables?
		Only works if the variable is in memory!
		Registers don't have memory addresses on x86
			DEC PDP-11 and IT-9900 apparently had them
	So we can't use write to write data from a register
		Only from
		We need to have a pointer for it
		Example from network programming

Where should buffers be?
	Example:  getcwd and get_current_dir_name
		Did we bring our own coffee mug?
