New commands `enable probe' and `disable probe'.
This patch adds the above-mentioned commands to the generic probe
abstraction implemented in probe.[ch]. The effects associated to
enabling or disabling a probe depend on the type of probe being
handled, and is triggered by invoking two back-end hooks in
`probe_ops'.
In case some particular probe type does not support the notion of
enabling and/or disabling, the corresponding fields on `probe_ops' can
be initialized to NULL. This is the case of SystemTap probes.
gdb/ChangeLog:
2015-02-17 Jose E. Marchesi <jose.marchesi@oracle.com>
* stap-probe.c (stap_probe_ops): Add NULLs in the static
stap_probe_ops for `enable_probe' and `disable_probe'.
* probe.c (enable_probes_command): New function.
(disable_probes_command): Likewise.
(_initialize_probe): Define the cli commands `enable probe' and
`disable probe'.
(parse_probe_linespec): New function.
(info_probes_for_ops): Use parse_probe_linespec.
* probe.h (probe_ops): New hooks `enable_probe' and
`disable_probe'.
gdb/doc/ChangeLog:
2015-02-17 Jose E. Marchesi <jose.marchesi@oracle.com>
* gdb.texinfo (Static Probe Points): Cover the `enable probe' and
`disable probe' commands.
