| 主权项 | 1. A processing system, comprising: a stack pointer configured to reference a first return address stored on a stack; a return address buffer pointer configured to reference a second return address stored in a return address buffer; and a return address verification logic configured to: responsive to receiving a return instruction, compare the first return address to the second return address, andresponsive to receiving a return address buffer modification instruction, perform at least one of: storing a return address in the return address buffer or removing a return address from the return address buffer, wherein the return address buffer modification instruction is a privileged instruction. | ||
