sdb,xdb: breakpoint on variables?

[Philip Abraham]

Is there a way in sdb or xdb to set up a breakpoint on a variable?
Execution should stop when that variable has been altered or
accessed (dereferenced). The man page (hp-ux 9.0) does
not specify any way to do this.
email preferred please. I will post summary.
Thank you in advance.

I think that dbx has "trace" and "when" commands which act on program
variables or at least my dbx has them.

gdb also has a watch command. However, all these options are
increadibly slow. If you have the cash, I highly recommend purify.
All in all an excellent tool, and includes in it's many capabilities
efficient watchpoints.
