Conditional Jumps Instructions No high-level control structures in assembly language The most common way to transfer control in assembly language is to use a conditional jump This is a two-step process: 1 First test the condition 2 Then jump if the condition is true or continue if it is false |
What is an unconditional jump instruction?
Unconditional jumps are the simplest form of jump instructions. As the name suggests, the execution will always flow to the target location specified. Following is the syntax of an unconditional jump instruction. Conditional jumps are used to take jumps based on the value of status flags.
What are conditional jumps?
All of the conditional jumps (like jne, jl, and many more) will jump based on the current setting of one or more of the bits in the FLAGS register. Besides the cmp instruction, there are many more instructions that will modify some of these bits in the FLAGS register (like test, add, and many more).
What is conditional execution in assembly language?
Conditional execution in assembly language is accomplished by several looping and branching instructions. These instructions can change the flow of control in a program. Conditional execution is observed in two scenarios − This is performed by the JMP instruction.
