DYNAMIC HARDWARE WATCHPOINT

摘要

A method and apparatus for monitoring changes to a block of data is disclosed. A computer sets a first hardware watchpoint to monitor changes to the block of data at a current location of the block of data in memory and a second hardware watchpoint to monitor changes at a selected location in the memory where a reference to the block of data is located. Responsive to the second hardware watchpoint being triggered by a change at the selected location where the reference to the block of data is located, the computer identifies a new location of the block of data in the memory based on the change that triggered the second hardware watchpoint. Subsequent to identifying the new location of the block of data, the computer then resets the first hardware watchpoint to monitor changes to the block of data at the new location of the block of data.
