* Fix powerpc dwarfless argument accessAnanth N Mavinakayanahalli2008-05-291-0/+7

* Handle bug #6500 fallout.David Smith2008-05-282-30/+93
| | | | | | | | | | | | | | | | | | | | | | | 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.`
* Minor improvement to multi-threaded support.David Smith2008-05-282-8/+33
| | | | | | | | | | | | | | | | | | | 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.
* Add prototypes for using the 2.6.26 probe_kernel_* functions.Josh Stone2008-05-273-35/+105
| | | | | | | | | For now, the autoconf for the new code is disabled, because it shows poorer performance than our existing dereferencing functions. This is probably because ours get inlined and optimized. The code is being committed so that we may re-evaluate its usefulness in the future. This addresses bugzilla 6432.

| | | | | | | | | | | | | 2008-05-16 David Smith <dsmith@redhat.com> PR 6499. * task_finder.c (stap_register_task_finder_target): Added error check. (__stp_utrace_task_finder_report_clone): Ditto. (stap_utrace_detach_ops): Uses do_each_thread/while_each_thread instead of for_each_process (which only iterated among process group leaders instead of all threads). (stap_start_task_finder): Ditto.

(__stp_utrace_attach_match_filename): New function. (__stp_utrace_task_finder_report_clone): Calls __stp_utrace_attach_match_filename() to attach to newly cloned threads.

|\ \ | |/ |/| | | PR 4311 - Function boundary tracing without debuginfo: Phases 1 and 2
| * Replaced [u_]arg() with [u]int_arg(), [u]long_arg(), {s|u}32_arg(),Jim Keniston2008-05-051-9/+66
| | | | | | | | | | | | | | {s|u}64_arg(), etc. Added asmlinkage(), fastcall(), regparm(). Dealt with some surprises -- e.g., rax is ZERO-extended eax. Seems to work well with -m32 and -m64 user apps, and with a (small) dwarfless subset of syscall.stp.
