commit 832f100d34c6e16222b5a380fbc87270c9cc488e
Author: Josh Stone <jistone@redhat.com>
Date: Tue Oct 11 16:55:59 2011 -0700
tracepoints: Add support for CONDITION events
These are events that check a condition before raising callbacks, but
take no hit for the condition when not tracing. We don't have to do
anything special in stap except handle the new macro, as the condition
is handled at the trace site.
* tapsets.cxx (tracepoint_builder::get_tracequery_modules): Add a
definition for DECLARE_TRACE_CONDITION. Also settle the macro-
arg wrappers to PARAMS().
commit a52d2ac00e1452cc3d2870f60523067ba766a791
Author: Josh Stone <jistone@redhat.com>
Date: Tue Oct 11 15:04:13 2011 -0700
tracepoints: Support reading enum parameters
* tapsets.cxx (resolve_tracepoint_arg_type): Treat enum like any other
numeric base type, simply casted to int64_t.
(tracepoint_derived_probe::build_args): Log parameter availability.
commit 8aa43b8d32dcd728a88250a9a53f803d37aaaab5
Author: Josh Stone <jistone@redhat.com>
Date: Tue Oct 11 14:15:27 2011 -0700
tracepoints: Skip identical headers from the build and source trees
In preparing the tracequery source, we normalize paths containing
"include/" to just the suffix part, so the header will be found by the
normal -I path. However, the debuginfo source tree usually contains
at least the same headers found in the build tree. We were thus
building effectively the same tracequery twice for headers that are
present in both the build and source trees. Stop that!
* tapsets.cxx (tracepoint_builder::init_dw): Build the header list with
knowledge of the "include/" normalization to avoid extra work.
commit 8e0a2563be208daf319d8eb720fc6236e211537d
Author: Josh Stone <jistone@redhat.com>
Date: Tue Oct 11 13:42:04 2011 -0700
tracepoints: Avoid building tracequery.ko targets
Since we're now only using the tracequery.o intermediates, we can forgo
building the tracequery.ko modules altogether. This saves about a third
of the processing time on my machine.
* buildrun.cxx (make_any_make_cmd): New, the common make_cmd base.
(make_make_cmd): The normal case targets "modules".
(make_make_objs_cmd): New, build only stage-1 objects.
(make_tracequeries): Call make_make_objs_cmd.
commit 2a0e62a892c4d3f4bbab29fac9105ec98594a2d1
Author: Josh Stone <jistone@redhat.com>
Date: Tue Oct 11 13:21:34 2011 -0700
tracepoints: Work with the tracequery's .o rather than .ko
The intermediate object files are slightly smaller, since they don't
have any of the module boilerplate compiled in yet. It still has what
we need though, just the basic stapprobe_* function definitions.
* buildrun.cxx (make_tracequeries): Return .o filenames rather than .ko.
* hash.cxx (find_tracequery_hash): Use .o for cached filenames.
* tapsets.cxx (tracepoint_builder::get_tracequery_modules): Update
comments and variable names to refer to objects instead of kos.
commit c252fca28cedf267799abdb2698abbb3e4f051ca
Author: Josh Stone <jistone@redhat.com>
Date: Tue Oct 11 13:13:40 2011 -0700
tracepoints: Cache an empty file for failures
When a tracepoint header doesn't compile for any reason, we'd like not
to keep trying on subsequent runs. This patch restores previous
behavior that would save an empty file in the cache, signaling that
we've tried this header before and can't get anything from it.
* tapsets.cxx (tracepoint_builder::get_tracequery_modules): When reading
from the cache, note and skip empty files. When saving to the cache,
copy /dev/null for those that failed to compile.
