[Bug translator/10995] on-the-fly enabled/disabled probes


http://sourceware.org/bugzilla/show_bug.cgi?id=10995

--- Comment #2 from Frank Ch. Eigler <fche at redhat dot com> 2012-12-11 20:23:14 UTC ---
bug #6503 added a derived_probe_group code generation function to
emit_module_refresh().  The code this generates would need to be extended with
per-probe predicate/registration-status bits in the runtime, and with code to
do any sort of lightweight arming/disarming that the probe system permits.  The
predicate-status bits would be mutexfully maintained by other code that
re-evaluates the probe predicate expressions periodically, or whenever the
input globals are suspected to change value.
