Abstract

See full text

An apparatus for monitoring changes to a block of data is disclosed. A first hardware watchpoint is set to monitor changes to the block of data at a current location of the block of data in memory and a second hardware watchpoint is set 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, a new location of the block of data in the memory is identified based on the change that triggered the second hardware watchpoint. Subsequent to identifying the new location of the block of data, the first hardware watchpoint is reset to monitor changes to the block of data at the new location of the block of data.
