The generated code now only checks the actionremaining count at control
points and after executing a large sequence of statements.
|
|
|
|
|
|

The old behavior was to check last_error all over the place, and if set,
jump to the out-label. Now it's changed to just jump to the out-label
directly after setting last_error.

./configure now accepts --enable-staticdw, which alters the link
settings so they work with static libdw.
Tested on Ubuntu Hardy.

The problem was caused by ptrdiff_t being a long on x86_64 and not
matching any of the overloaded definitions of dwfl_assert.

New dwarf_wrappers.h, dwarf_wrappers.cxx for for idiomatic access to
libdwarf and refactoring somethings out of the giant classes in tapsets.cxx.

* tapsets.cxx (enum utrace_derived_probe_flags): Redefined in
terms of probe types instead of utrace events.
(utrace_var_expanding_copy_visitor::visit_target_symbol): Uses new
utrace_derived_probes_flags values.
(utrace_builder::build): Handles new probe types and new
utrace_derived_probes_flags values.
(utrace_derived_probe_group::emit_probe_decl): Updated to handle
new utrace_derived_probe_flags values.
(utrace_derived_probe_group::emit_module_decls): Ditto. Also
correctly handles 'begin' events correctly by installing a quiesce
handler (instead of running the probe directly).
(register_standard_tapsets): Registers updated utrace probe
types.
2008-06-06 David Smith <dsmith@redhat.com>
* task_finder.c: Added some debug logic. Use
'-DDEBUG_TASK_FINDER' to enable.
(stap_utrace_attach): Renamed from '__stp_utrace_attach'.
(__stp_utrace_attach_match_filename): Calls callback with
notification that this is a process or thread event.
(__stp_utrace_attach_match_tsk): Ditto.
(__stp_utrace_task_finder_report_clone): Ditto.
(__stp_utrace_task_finder_report_exec): Ditto.
(stap_utrace_task_finder_report_death): Ditto.
(stap_start_task_finder): Ditto.
(stap_stop_task_finder): Added debug logic.
2008-06-06 David Smith <dsmith@redhat.com>
* systemtap.base/utrace_p4.exp: Updated for utrace probe changes.
* systemtap.base/utrace_p5.exp: Ditto.

hence systemtap build fails on s390. So use -fPIE which doesn't put limit on GOT size.
