摘要：
A processor of an aspect includes a decode unit to decode an instruction. The processor also includes an execution unit coupled with the decode unit. The execution unit, in response to the instruction, is to determine that an attempted change due to the instruction, to a shadow stack pointer of a shadow stack, would cause the shadow stack pointer to exceed an allowed range. The execution unit is also to take an exception in response to determining that the attempted change to the shadow stack pointer would cause the shadow stack pointer to exceed the allowed range. Other processors, methods, systems, and instructions are disclosed.
