Added tests for 'process(PID)' variants. This commit makes changes to the VFS tapset. The changes include deprecation of syscalls2.stp: Add sys_renameat. Only probe lines once for the :* wildcard line pattern. Revert checking address in runtime bz451707: fix conversions.exp test $name Cleanup in tapsets.cxx Added powerpc support to runtime/syscall.h.

| | | | | | | | | | | | | | | | | | | | | | | 2008-05-28 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_derived_probe_group::emit_probe_decl): Instead of adding clone handlers, just call the probes directly. (utrace_derived_probe_group::emit_module_decls): For syscall probes, on exec detach the parent's utrace engine from the child. 2008-05-28 David Smith <dsmith@redhat.com> * task_finder.c (__stp_utrace_attach_match_filename): Added register_p parameter, which is passed on to the callback. Only adds death notification if register_p is 1. If register_p is 0, removes death notification. (__stp_utrace_attach_match_tsk): Moved code from __stp_utrace_task_finder_report_clone that handles the details of grabbing a task's path. (__stp_utrace_task_finder_report_clone): Calls new __stp_utrace_attach_match_tsk(). (__stp_utrace_task_finder_report_exec): Notifies upper layer that it might need to detach from newly exec'ed process.`

| | | | | | | | | | | | | | | | | | | 2008-05-21 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_derived_probe_group::emit_module_decls): Added new 'event_flag' parameter to task_finder callback. Only calls probe handlers if we received the correct event. 2008-05-21 David Smith <dsmith@redhat.com> * task_finder.c (__stp_utrace_attach_match_filename): Added event_flag parameter of event to pass to callback. (__stp_utrace_task_finder_target_death): Ditto. (__stp_utrace_task_finder_report_clone): Calls __stp_utrace_attach_match_filename() with new argument. (__stp_utrace_task_finder_report_exec): Ditto. (stap_start_task_finder): Calls callback with an invalid event_flag since this callback call isn't related to an event.
