-/* However, some addresses may not be profitable to use hardware to watch,
- or may be difficult to understand when the addressed object is out of
- scope, and hence should be unwatched. On some targets, this may have
- severe performance penalties, such that we might as well use regular
- watchpoints, and save (possibly precious) hardware watchpoints for other
- locations.
-
- On HP-UX, we choose not to watch stack-based addresses, because
-
- [1] Our implementation relies on page protection traps. The granularity
- of these is large and so can generate many false hits, which are expensive
- to respond to.
-
- [2] Watches of "*p" where we may not know the symbol that p points to,
- make it difficult to know when the addressed object is out of scope, and
- hence shouldn't be watched. Page protection that isn't removed when the
- addressed object is out of scope will either degrade execution speed
- (false hits) or give false triggers (when the address is recycled by
- other calls).
-
- Since either of these points results in a slow-running inferior, we might
- as well use normal watchpoints, aka single-step & test. */
