摘要：
A method for identifying memory modifications includes designating a first portion of a first memory as read-only. An abort condition is identified responsive to receiving a write instruction having a target address within the first portion. In response to the abort condition, a second portion of the first memory including at least the target address is flagged as being modified. The write instruction is executed.
