I am finishing my thesis in which I made significant improvements to
"watchpoints" in GDB. Watchpoints are "data breakpoints": memory
locations that when changed cause the program to stop and give control to
As part of the research I need to compare with other debuggers. If you
know of other debuggers that implement watchpoints, please let me know.
In any case, if you know the debugger or can cite a reference for the
debugger on these OS's, please respond. Thanks!

Specifically I would like to know:
1. Does the debugger provide data breakpoints?
2. If it does, must you watch specific memory locations or can you
watch an arbitrary expression?
3. How is it implemented: single stepping, virtual memory, monitor
registers, code patching, other?
