L09: x86-64 Programming II. Conditionals and Control Flow. ? Conditional branch/jump. ? Jump to somewhere else if some condition is true.
Then jump if the condition is true or continue if it is false. Conditional jump instructions can be divided into four groups: 3. Jumps based on the value of a
Unconditional Jumps. • Two kinds of jumps/branches. • Conditional. – Jump only if a condition is true otherwise continue sequentially. – x86 instructions:
