WebControl flow predictions determined by the actions of code in the target execution context or contexts appearing in program order before the instruction cannot exploitatively control speculative execution occurring after the instruction is complete and synchronized. WebSoftware interrupts are triggered by the instruction int. For example, the instruction "int 14h" triggers interrupt 0x14. The processor then stops the current program, and jumps to the code to handle interrupt 14. When interrupt handling is complete, the processor returns flow to the original program.
