The master branch has been updated by Tom de Vries <vries@sourceware.org>:

    [gdb/cli] Add maintenance ignore-probes

    There's a command "disable probes", but SystemTap probes, for instance
    libc:longjmp cannot be disabled:
    ...
    $ gdb -q -batch a.out -ex start -ex "disable probes libc ^longjmp$"
      ...
    Probe libc:longjmp cannot be disabled.
    Probe libc:longjmp cannot be disabled.
    Probe libc:longjmp cannot be disabled.
    ...

    Add a command "maintenance ignore-probes" that ignores probes during
    get_probes, such that we can easily pretend to use a libc without the
    libc:longjmp probe:
    ...
    (gdb) maint ignore-probes -verbose libc ^longjmp$
    ignore-probes filter has been set to:
    PROVIDER: 'libc'
    PROBE_NAME: '^longjmp$'
    OBJNAME: ''
    (gdb) start ^M
      ...
    Ignoring SystemTap probe libc longjmp in /lib64/libc.so.6.^M
    Ignoring SystemTap probe libc longjmp in /lib64/libc.so.6.^M
    Ignoring SystemTap probe libc longjmp in /lib64/libc.so.6.^M
    ...

    The "Ignoring ..." messages can be suppressed by not using -verbose.

    Note that as with "disable probes", running simply "maint ignore-probes"
    ignores all probes.

    The ignore-probes filter can be reset by using:
    ...
    (gdb) maint ignore-probes -reset
    ignore-probes filter has been reset
    ...

    For now, the command is only supported for SystemTap probes.
