Integer Arithmetic Instructions

These instructions operate on registers or memory. S,D represent source and destination.[for ldiv, D must be %eax, and cdq must be used before the divide to sign-extend %eax into %edx, which of course changes %edx.] Usually, S is the rhs and D is the lhs.

addl		S,D		D + S → D
subl		S,D		D - S → D
imull		S,D		D * S → D
ldiv		S,D		D / S → D
cmpl		S,D		compare D - S , set condition
andl		S,D		D ∧ S → D
orl		S,D		D ∨ S → D
notl		D		¬ D → D
negl		D		- D → D

Note that arithmetic can be done directly on memory:
i := i + 1 can be one instruction:

   addl $1,-32(%rbp)
