@subsection Static Probe Points
|
||||
|
||||
@cindex static probe point, SystemTap
|
||||
@value{GDBN} supports @dfn{SDT} probes in the code. @acronym{SDT} stands
|
||||
for Statically Defined Tracing, and the probes are designed to have a tiny
|
||||
runtime code and data footprint, and no dynamic relocations. They are
|
||||
usable from assembly, C and C@t{++} languages. See
|
||||
@uref{http://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation}
|
||||
for a good reference on how the @acronym{SDT} probes are implemented.
|
||||
|
||||
Currently, @code{SystemTap} (@uref{http://sourceware.org/systemtap/})
|
||||
@acronym{SDT} probes are supported on ELF-compatible systems. See
|
||||
@uref{http://sourceware.org/systemtap/wiki/AddingUserSpaceProbingToApps}
|
||||
for more information on how to add @code{SystemTap} @acronym{SDT} probes
|
||||
in your applications.
|
||||
|
||||
@cindex semaphores on static probe points
|
||||
Some probes have an associated semaphore variable; for instance, this
|
||||
happens automatically if you defined your probe using a DTrace-style
|
||||
@file{.d} file. If your probe has a semaphore, @value{GDBN} will
|
||||
automatically enable it when you specify a breakpoint using the
|
||||
@samp{-probe-stap} notation. But, if you put a breakpoint at a probe's
|
||||
location by some other method (e.g., @code{break file:line}), then
|
||||
@value{GDBN} will not automatically set the semaphore.
|
||||
|
||||
You can examine the available static static probes using @code{info
|
||||
probes}, with optional arguments:
|
||||
|
||||
@table @code
|
||||
@kindex info probes
|
||||
@item info probes stap @r{[}@var{provider} @r{[}@var{name} @r{[}@var{objfile}@r{]}@r{]}@r{]}
|
||||
If given, @var{provider} is a regular expression used to match against provider
|
||||
names when selecting which probes to list. If omitted, probes by all
|
||||
probes from all providers are listed.
|
||||
|
||||
If given, @var{name} is a regular expression to match against probe names
|
||||
when selecting which probes to list. If omitted, probe names are not
|
||||
considered when deciding whether to display them.
|
||||
|
||||
If given, @var{objfile} is a regular expression used to select which
|
||||
object files (executable or shared libraries) to examine. If not
|
||||
given, all object files are considered.
|
||||
|
||||
@item info probes all
|
||||
List the available static probes, from all types.
|
||||
@end table
|
||||
|
||||
@vindex $_probe_arg@r{, convenience variable}
|
||||
A probe may specify up to twelve arguments. These are available at the
|
||||
point at which the probe is defined---that is, when the current PC is
|
||||
at the probe's location. The arguments are available using the
|
||||
convenience variables (@pxref{Convenience Vars})
|
||||
@code{$_probe_arg0}@dots{}@code{$_probe_arg11}. Each probe argument is
|
||||
an integer of the appropriate size; types are not preserved. The
|
||||
convenience variable @code{$_probe_argc} holds the number of arguments
|
||||
at the current probe point.
|
||||
|
||||
These variables are always available, but attempts to access them at
|
||||
any location other than a probe point will cause @value{GDBN} to give
|
||||
an error message.
