cmp instruction in 8086 with example

Apr 27, 2017 - assembly x86. I am trying to figure out the behavior of conditional jumps (JE/JNE, JZ/JNZ) in the x86 instruction set familly. Which condition flags CMP instruction The cmp instruction is used to perform comparison. It's identical to the sub instruction except it does not affect operands. It impacts the Zero Flag (ZF) as well as In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF , ZF , PF are modified while the result of the AND is Mar 13, 2013 - The CMP instruction is typically used in conjunction with a conditional jump (Jcc), condition //Modify status flags in the same manner as the SUB instruction Almost all programming languages have the ability to change the order in which statements are evaluated, and assembly is no exception.
