[Bug translator/3555] New: systemtap timing option (-t) is broken

["wcohen at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

The testsuite/systemtap.base/bench.stp fails because the build fails. End up
with lots of errors of the form.

/tmp/stapjohndu/stap_4b1a4da52601e6e3194a1345ee026b3d_17168.c: In function
'systemtap_module_init':
/tmp/stapjohndu/stap_4b1a4da52601e6e3194a1345ee026b3d_17168.c:1093: error:
'time_probe_2' undeclared (first use in this function)
/tmp/stapjohndu/stap_4b1a4da52601e6e3194a1345ee026b3d_17168.c:1093: error: (Each
undeclared identifier is reported only once
/tmp/stapjohndu/stap_4b1a4da52601e6e3194a1345ee026b3d_17168.c:1093: error: for
each function it appears in.)

Looking through the test archives it broke between Oct 27 and Nov 1. The
following changes in the translator are listed in ChangeLogs:

>       Probe registration rework.  Offline dwarf processing for better
>       cross-instrumentation.
>       * elaborate.h (derived_probe): Remove registration-related code
>       generation API.  Add new function sole_location().
>       (derived_probe_group): Reworked this and associated classes.
>       * session.h (systemntap_session): Create individual per-category
>       derived_probe_groups.
>       * elaborate.cxx (derived_probe_group): Reworked.
>       (alias_derived_probe): Switch to new derived_probe API.
>       (semantic_pass_symbols): Ditto.
>       * translate.cxx (mapvar init): Check for array initialization error.
>       (emit_module_init): Handle such failures, at least in theory.
>       (emit_module_exit): Switch to new derived_probe_group API.  Call
>       cpu_relax() during shutdown busywait.
>       (emit_common_header): Elide context variables for elided handler fns.
>       (c_unparser::emit_probe): Implement new, improved duplicate
>       elimination technique for probe handlers.  Leave two older ones
>       behind as compile options for education.
>       * tapsets.cxx (*): Reworked all probe registration code, moving
>       it from derived_probes into derived_probe_groups.  Shrunk output
>       code.  Temporarily disabled probe timing and perfmon/mark probes.
>       (dwflpp): Use offline reporting, so that module matching and
>       relocation is performed at run time.
>       (dwarf_query): Remove flavour logic, now supplanted by other
>       duplicate elimination code.
>       (dwarf_derived_probe): Reworked construction, centralized
>       module/section/offset computations.
>       * tapsets.h (all_session_groups): New little helper.
>
>       * main.cxx (main): For pass-2 message, print number of embeds too.
>       * systemtap.spec.in: Add a "BuildRequires: dejagnu" for make check.
>       * configure.ac: Bump version to 0.5.11.
>       * configure: Regenerated.
>
> 2006-10-23  Li Guanglei <guanglei@cn.ibm.com>
>
>       * lket.5.in: Rearranged the sections, add more details.
>
> 2006-10-30  David Smith  <dsmith@redhat.com>
>
>       * stap.1.in: Added notes about new caching feature.
